  1. Hi guys. the boat was inspected and was found this: "no continuity was found between the aluminum fuel tank and the vessel's DC negative/engine. Investigate further and correct as necessary ensuring the fuel tank is grounded to the vessel DC negative engine resistance between the two is less than one ohm. ABYC H24" Soooooo.... 1) what am I looking in here? 2) a broken wire? 3) DO I have to make one? 4) what am I looking for? 5) or where should I look for? 6) is this wire should be connected to the tank itself or the sender or somewhere else? 7) my fuel gauge seems not too accurate. in the water shows something different than on the trailer. ex: in the water shows 1/2 on the trailer full! so, could this be the problem? or a sender problem? or a gauge problem? all the above? thank you guys! this is a 2004 Chap 260 Signature
  2. I have a 2008 Signature 310 with Mercruiser 5.0 engines and Bravo 3 drives, I have only operated the boat on inland lakes and am planning a trip from South Florida to the Bahamas. Can anyone give me an idea of typical fuel flow and perhaps fuel economy and suggested cruising speed. I know the fuel flow that shows on the instrument panel but was hoping someone had “real world” experience. Thanks
  3. Hello all,This is my first time posting and trying to work on my fathers boat (and keep it out of the shop)We have what I believe is a fuel pressure issue on his 2002 Chaparral 242 Sunesta with a 5.7 GI Volvo Penta Dual Prop I/O. It just started this year after pulling out of storageSymptoms:- The engine will start no problem but can be felt chugging at low RPMS. At higher RPMs it is less noticeable but the boat is still only getting about 50% power (used to do 45mph now tops out at 25mph)- The engine responds and increases throttle but if you throw it back to idle or neutral the engine dies out.Troubleshooting:- We replace the fuel/water separator (no change)- Clean spark plugs. These did not appear to be in bad shape. Normal discoloration (no change)- Added seafoam to gasoline (no change)- Used a screwdriver to feel that all injectors were firing. Some felt lighter than others but all could be felt clicking- Checked the fuel pressure on the rail. The fuel pressure bounced between 50-54 PSI when under load so it was not stable which i would expect it to be.- Replaced the fuel pressure regulator. When we did this, the boat would not start at all unless we gave it throttle and would not stay running unless we kept the throttle up. I got this part from a dealer so I would hope they gave me the right one.- Reinstalled old fuel pressure regulator since the new one seemed to make the issue worse.- Checked the impeller. It is in good shape.Next steps:I've done a ton of digging but can't find any other examples of where the pressure was not stable at the rail. I would like to say the fuel pump itself needs replaced but if the pump is outputting anything higher than 50 psi I would expect the pressure regulator should hold it stable. So I am at a loss.Thanks for any suggestions-Kyle
  4. We purchased last Spring (2016) a brand new Vortex 223 VRX. First - I do love this boat, there are pros and cons (Dang this boat is LOUD), but right now the pros outweigh the cons. But since purchasing the boat, I have had fuel gauge accuracy issues on the Medallion Screen. The first issue was literally topping off the fuel and the medallion screen will never registered a full reading. Always off by about 1/4 of a tank right at the fuel dock. Obviously underway and moving the gauge will creep towards full before the boat planes off, but when the boat is plane, parked, at the dock, or on the lift - the gauge will never reach Full, only 3/4. Is this normal for others who own this make/model? The Chaparral dealer considered ordering a new "sending unit", but their tech tried some other adjustments that appeared to help for about one weekend, but then returned to the inaccuracies soon afterwards. I just decided, I could probably live with the inadequacy, but this summer (2017) the problem seems to be worse and I get low fuel warnings frequently after having filled the boat up earlier in the day. I have documented pretty well the gauge reading and warnings and how much fuel we add after those readings and warning to estimate how much fuel is actually left. Before disclosing those readings, I was hoping to get some documented response from Chaparral on a few questions in regards to the gauge reading on a 2016 vortex 223 vrx with medallion screen. So - My boat specs say I have a 52 gallon tank. 1st question for Chaparral or other vortex owners with the same specs as I ... Do other owners also have issue that after they top off their boat with fuel, their fuel gauge is reading closer to 3/4 full instead of full? 2nd question: When your gauge reads 1/2 of fuel - how many gallons of fuel would you expect to be left or how many gallons would you expect to add to the boat to fill it up? (seems logical with a 52 gallon tank, but my experience is anything but). 3rd question: When the "low fuel warning" comes on (usually around 1/4 of a tank), about how many gallons of fuel would be expected to be in the tank? So in other words Chaparral and other Vortex Owners - at a 1/4 and/or when the "low fuel warning" is displayed on the medallion screen - how much fuel would you estimate would still be in your 52 gallon tank at this point? I know answers will vary, but I am just needing to find averages to go on so that I can determine if this is an actual problem, or if the gauges on fuel in this boat are this inaccurate and unreliable. This is not my first boat, I have owned about a dozen different makes and models over my lifetime, and some have had accurate and dependable gauges for fuel, others - not so much. I just sort of expected a boat of this caliber and technology to have something a little more accurate and dependable. So fellow Vortex owners or Chaparral reps/techs, please let me know your thoughts and experience with this. I need to know if I need to press for a repair or warranty concern, or if it "is what it is" scenario. Thank you, SM
  5. Our 2004 Chaparral 290 Signature is undergoing surgery! The fuel tank has to be replaced due to a persistent leak identified last October. Fiberglass workers have already removed the Aft cabin floor to expose the tank (and ventilate). Talks now indicate that further cuts will be necessary to get the tank out. They are proposing to remove the bulkhead in the engine compartment (mid cockpit) in order to be able to maneuver the tank out but at additional cost and time and obvious surface area intrusion. So the question to the forum is,: 1) Does this seem extreme for those who have been successful with replacing a leaking fuel tank? 2) Has Chaparral provided any guidance for the task that was helpful? We plan to reach out tomorrow to headquarters. 3) Has insurance covered the extensive work required? At this point they are balking and challenging to whether we just total the boat and receive a check. Appreciate any relevant replies and personal experience to shed light on our challenges. Thanks
  6. I have a 2016 H20 sport 21' and in the ski storage locker located between the captain and passenger seat will not drain. There is a drain in the aft wall however the problem is that the fuel tank is pushed up so close to the drain hole that it prevents any water from exiting into the bilge. I have contacted Chaparral about this and they sent me an email with pictures of how to fix. They show to drill a hole in the locker floor board just in front of the hole on the wall and that should do it. However, I have drilled into the floor 3 1/2" and it did not open up. I did not want to drill any deeper. Its so frustrating and now I have a 3" deep hole in my locker. Has anyone else had this problem? It appears that someone didn't take the time to make sure the tank was moved back away from the hole. Any help would be appreciated.
  7. Hi, I recently had fuel stolen from my boat while it was in storage. I have a 2018 H2O Surf. I had a half tank left in the boat. Went to take it out 4 days later and my fuel gage said 2%. I live in Gilbert AZ. The storage unit is next to an area where it looks like some one would take advantage of the situation. Is there a solution fir a lockable Fuel cap for my boat? Thank you!!! Th
  8. I have a 2003 chaparral signature, I bought in April, it has run great and haven't had any problems until yesterday. I was moored on the beach and when it was time to leave my boat would start then immediately die It did this about 10 times, then we pushed the throttle down and got it to start. was able to get back to my dock, shut is down and it started back up. let it sit without shore power for about an hour tried starting it and it immediately died. Hooked it up to shore power left it over night, went to start it up and it started right up with no problems. I am afraid to take it out on lake Michigan if I can't trust it. I thinking it could be a fuel issue as I hear my fuel pump run constantly when I turn on my batteries ( is this normal) , or a battery issue. ( am I supposed to switch from shore to AC main when I am out on the water?) Any help would be appreciated.
  9. I have a 1994 Mariner 75hp 3 cylinder OB and it will run for a while just fine but then when you go to restart it you have to keep pushing in the key to keep the motor running. Even after a short warm up. When the key is pushed in the idle with pick up 2k and run fine for a little while then it will start to bogg down again.
  10. I just bought my first boat and did not know what to look for. Once I started playing around with all the issues I noticed the previous owner had covered up the ski locker where the fuel sending unit is located. I'm ready to drill in and access port but I'd like to make it right over top of the sending unit and only drill one hole. Could somebody please help me out locating this on a 1994 1830 SS? Not only is the gas gauge now working but the water temp gauge doesn't work either. Must be the gauge our wiring sense I replaced the sender. Any help with pictures or measurements would be greatly appreciated.
  11. I have an 1997 Chaparral 1830SS with an 4.3 liter V6 Mercruiser engine. The gas tank holds 30 US gallons according to info. from several online sources. I want to use up as much of the current ethanol additive gas now in the tank before I fill up with NON-ethanol. My question is assuming my gas tank sending unit & gas gauge are "reasonably" accurate, how much should I use up before refilling to get maximum benefit from the non-ethanol diluting the current ethanol blend. Next question: Is it likely the gas gauge will drop by 1/4 when 1/4 tank of gas is actually used. Meaning how much can I or you trust the gas gauge to not let us run out of gas assuming we pay attention to it's reading. Obviously running out of gas would really ruin our day. The ladies especially. My objective is to maximize the benefits of at least an occasional fill up with non-ethanol gas without running out of gas. Thank you for your comments.
  12. I am having fuel delivery trouble with my 1990 Chaparral 1800 SL. So far I have replaced what I believe is a perfectly good fuel pump with a new one. I removed the out line from inside the fuel cell and checked the screen type filter on the bottom end and it is clear of all obstruction. I have replaced the fuel hose with the upgraded fuel hose from tank to pump, (just in case the line was breaking down internally.) I have completely discarded the fuel filter, (at least until I get this fuel delivery issue resolved.) Now this brings me to the forward, 151A, (late model), carburetor. There is a vacuum line that routes from the flange of the forward carb down to the fuel pump. The forward carb has very low vacuum and when adjusted for balance it runs like junk. The rear carb has terrific vacuum and can be adjusted like normal. I can find no vacuum leaks. OK, now the past symptoms are as follows; Drop boat in water. Fire off the engine and it fires right away. Sounds really good Take boat out on the water and run it hard or easy for 15 to 20 minutes. Stop engine and fish for an hour or so. Engine will not fire again and there is no fuel in the lines and/or carbs. I dont understand that vacuum hose from forward carb to fuel pump. What is that vacuum line supposed to do? Is that vacuum line there to assist the fuel pump ..... Kind of like a mechanical over vacuum (or vise versa) fuel pump? Why can I not get any measurable vacuum in the forward carb?
  13. I see some of the smart tab manufacturers make claims of ~10% savings in fuel when using smart tabs. Anyone have any experience with them?
  14. I am dealing with a problems with my 290 Signature. About a month ago, I opened my engine room hatch and discovered raw fuel in the bilge (about 2" deep). The boat has been secured and all of the fuel has been pumped out of the tank and through a series of tests we have confirmed it is the tank leaking. Chaparral and the dealer both say that the generator and both engines have to be removed and the forward firewall and aft berth floor cut and removed to get at the tank. Does anyone have any experience with replacing the tank in this model? Method? Pictures? Thanks, Goula Guy
  15. I've got a 2013 196ssi that I can't seem to get more than a gallon in at a time. It's got a fuel filler cap on both sides but both only take a little bit at a time. Any help would be appreciated.
  16. My current routine is to go the gas station down the street and fill two 6 gallons canisters with high-dollar E-free fuel. When someone asked me why I did this, I responded that it had something to do with corroding the fuel tank if it had ethanol. After the words fell from my mouth I started questioning the veracity of that statement. So two things: 1) Can anyone definitively say just exactly WHY I have to use ethanol free fuel in my 2006 SSI 260? (Mercruiser) 2) Is there a scenario whereby I could use regular gas in my tank? If it's a corrosion thing, is there a method/kit to switch out the tank? What is this madness!? Thanks.
  17. I am thinking about buying a 2007 280 signature. Does any one have any fuel consumption data?
  18. 2007 Chaparral 210 SSi with Mercury Mercuiser 5.0 MPI engine (260 hp) – 160 hours The problem I’m experiencing happens after we’ve been doing water sports by pulling a person on a tube or wakeboard. Once somebody is finished with their water sport, I stop the boat engine to let the person back on board the boat. Most times the boat starts and runs fine. But then sometimes the boat will start and the engine will quit after a second or two. On subsequent attempts, the same thing happens: the boat starts but then only runs for a second before the engine quits. We’ve been towed back three times last year due to this problem. The next day, the engine starts and runs fine. I took my boat to the Chaparral dealer for repair twice. They did the following maintenance: · Change pickup in gas tank. · Clean out anti-sip valve. · Scan engine for fail codes. · Installed new impeller kit. · Replace water pump housing. · Check fuel and replace fuel filter. Notes: This is an intermittent problem which is very difficult to reproduce. It seems to only occur after stressing the engine from pulling people. After the engine has cooled for a long enough time, the engine will run. If you have any ideas on what this problem might be, please let me know. Thank you.
  19. Fuel/surging problem; any help would be appreciated. 2001 216SSI, Merc 5.0L EFI. Serious surging RPM issues when i can get it started--which is about every 5th attempt. It will sometimes run in idle but low (600 RPM) and very rough, for maybe a minute; then will sputter and die when I try to fast idle the RPM up. I've added good additive to the fuel, trailered the boat a little to agitate it in the tank, and changed the fuel filter twice. When I added clean fuel to the new filter, the boat ran normal until the fuel in the new filter was burned up, then back to surging or no start. I talked to my Mech briefly, who said check the anti-siphon valve, and tried to talk me through that as a last resort before I have to take it to him and let it sit for a month before he can get to it. Here's my lamen's dilema: Is the valve attached to the tank line underneath the edge of the floorboard (ie, take the floor up to get to it?), or is it the valve where the line comes into the top of the fuel fitler assembly, on my 5.0L engine? Thought I'd try the forum avenue for any info--much appreciated.
  20. I can not locate which fuel is recommended for a 2006 256 SSI. have heard different views on this, so more confused than ever. looking for any info. Thanks
  21. I just bought a 2006 sunesta 254 Volvo penta 5.7 76 hours and took it out on the water today. Backed it down in the water and it started right up. Eased away from the dock and once I was out side of the wake zone throttled up. At about 3000 rpm it died. Started it right back up and tried again and it did the same thing at around 3000 rpm. It started right up for the third time so this time I throttled up slower and did not have any issue getting up on plan. Drove at about 3700 for about 2 min and then made a left turn and it did again. This time it would not start or do anything. The fuel gauges show that it is complete full of full but I was beging to have my doughts. I pulled the fuel filter and it looked like it was only about half full of fuel. I called the dealer that I had just left and told him of this issue just to make a point. Then called sea tow which was given from the dealer. I a asked if they could bring me some gas thinking that I had run out of gas. They brought me 15 gallons of gas and started dumping it in. on the last can of gas I had about 2.5 gal left in the can and gas start to over flow out of the tank. I stopped pouring gas and waited a couple of mins think that I had and air issue with the tank. Went and started it up and it started right up. When back and tried to add the remainder of the gas (2 gal) but the tank just would not take any more. We decided to go and stay out for a while and see what happens. After 2.5 hours of running and pulling a tube we put it back on the trailer with no other issues. Does anyone know if these tanks have an extension hose on the fuel tank that can come off in the tank and cause it not to be able to pick up fuel unless complete full of fuel. Thanks for any help.
