    propeller size & pitch

    I am running a 14.5x17 aluminum on my 1995 2335 5.7 4 barrel alpha one generation 2. I reach WOT 4400-4600 at about 42 miles a hour. My boat is a little bigger and heavier. That 14.5 makes a big difference from a 15x17 on my boat. Just a guess maybe a 14.5 x 19 for you? I would continue to look around and get some other input. I would think a boat that size with a 5.7 fuel injections should make 50+ mph with the correct prop. Maybe you can borrow a few to see what works best. Let us know what works

    WOT range for 1999 5.7 injected

    Ingalp01, A half quart seems to be a lot for an Alpha one gen 2. (just a thought, maybe it was not done correctly) It is important when changing outdrive oil that it is pumped in from the bottom with the vent open in the top. I pump it in until it comes out the vent and fill the reservoir afterwards. I always notice the reservoir drops between 1 and 2 inches after running for a few minutes and top off. At that point it should find its level.

    WOT range for 1999 5.7 injected

    Ingalp01, Drive oil should never drop with the exception if you just changed the drive oil and the oil has not found it's level from the drive to the reservoir. Another possibility is reservoir leakage (if your lucky) otherwise, it may be down under the waterline not a good thing. The first thing I alway do when I get the boat in the driveway is to pull the drive drain plug to check for white milky oil. I am running a Alpha one Gen 2 outdrive that is 22 years old and preparing for the worse. I consider myself very lucky. I been looking to see what the solution will be when it finally goes. The boat has been well maintained, but for it's age it maybe more economical to use a cheap "knock-off drive" or one that have been rebuilt by professional. Good luck

    WOT range for 1999 5.7 injected

    Ingalp01, A little to high for my liking.. I have a 1995 2335 5.7. I get goose bumps at 4500 rpm. I am getting 45 mph with GPS and aluminum prop. 14.5 x 17. I don't keep it there for more than 30 seconds. I can cruise at 30 mph at about 3000 rpm. It is a good number because the secondaries do not kick in and you can save some gas. Don't quote me but I would say 6 gallons a hour. I believe the boat weighs in at 4650 lbs empty.

    WOT range for 1999 5.7 injected

    My 1995 2335 5.7 has 4200-4600 it is identified right above the flame arrestor (see picture) My manual say's 4400-4600 rpm. The original engine was changed to a 260 hp but I would say they must be about the same.

    More fuel issues

    Just a thought, on the secondaries. Just a quick check. I had someone punch the throttle in neutral fast and hard while I video recorded it. It was to dangerous to squeeze my face over the throttle plates (no head room). You should be able to see the secondaries kick in and open. I did not exactly record the opening rpm but I was alway under the impression they open at 3200 rpm's ( I sure it is in the manual somewhere) They definitely opened up. This was on a 350 magnum 1995 with a Weber 4 barrel.

    More fuel issues

    What is it a "check valve" ?
  12. I have a 1995 Chaparral Extended plane-anniversary edition 2335 350 Mercruiser. I was browsing engine spec's in Sea Loc and could not help but note there is a 5.7L 4 Barrel carb Alpha one (235 hp) and a 5.7 Magnum (250 hp) 4 barrel carb alpha one. Does anyone know how to identify the difference?
  13. To all, I want to personally thank Wing Nut for all the information he sent me yesterday. I knew the guy was a "stand out" and had a lot of knowledge with Mercruiser's The Chaparral blog is really a great place to get information and meet new friends. Yesterday I did both.. Best of wishes to the membership, Allen arowles@comcast.net

    Trim not reacting properly

    Funny topic, I was out today and put a few hours on the boat and I noticed the trim switch up does not work up but the trailer switch up works, and the down works fine. Just when I thought I would get a break from the next repair. "BOOM" the next thing need repairs. I don't hear the solenoid clicking up. I do have an extra Quicksilver Controller 3000 trim switch in the garage from the last repair maybe 2 years ago when the controller handle broke. Been there done that before. I really use the trim switch a lot because of low tide in the harbor demands triming up at low tide coming into the dock. If I remember correct you have to test for control voltage on the up solenoid. I don't remember if the "trailer switch" goes thru the trim switch or not (I don't think it does because the motor will grunt up if you are using the trailer switch. At any rate, as all you may know.... most boat need continued repairs and maintenance.

    Mechanical Issues on motor

    Poverty 88, You may want to look at the neutral kill switch adjustment and/or function. Personally speaking I have a 5.7 Mercruiser 1995 and once in a great while I have "center" the controller. i.e. reverse to forward and find the sweet spot (neutral) You would be surprised. I have assisted a few out on the docks that had the same problem. Technically speaking, the neutral switch on the carburetor kills the engine as you go from forward to reverse- Reverse to forward for a split second. A bad adjustment could have some impact. Just a little adder; Wingnut most likely has it. Its been some long since the neutral kill switch acted up I can not remember if it takes out the ignition including starter cranking or just the ignition. Let us know what you find...

    Alpha one Gen2 trim limits

    On my Alpha one Gen 2, It obviously will stop in the up position until it gets the trailer point. Going down you watch the gauge and listen for the pump to grunt. I grunt it down before I accelerate and get ready to come out of the water. Being up just a little can really have a impact on coming up on plane.
  17. Hi Everyone, Now that I got my overheating issue resolved I would like to get my alarms working. I grounded out my temperature sensor and not getting any alarm. I tried to get a picture of the buzzers. There appears to be two grouped together. Does anyone know where to buy replacements buzzers. Additionally I do not get the short alarm when the key is turned on. I tried to take a picture of the part number without much luck.

    Instrument lighting

    In my opinion, dim lights on a 12 volt system could be a high resistance connection somewhere. My instrument panel uses a common ground (black). If they are all dim I would look into the common issues. Get the wiring diagram and check on terminal points, splices or connectors. The degradation-corrosion of connections is elevated especially if the boat spends a lot of time in an salt environment. Just some simple thoughts.

    1995 2335 Boat alarms Temperature and oil

    I changed the alarm buzzer and reworked two splices next to the buzzer to insure they were not high impedance connections. Now working. It appears no holding circuit if the engine is not running you get an alarm. I would take an educated guess; no oil pressure running or not an alarm state happens. Still have not tested the overtime alarm but that is another day. I still have not figured out the gauge issue on the blue lights issue may Cyclops 2 may be right.... The gauges appear to have an additional wire on them that does not show up on the instrument panel wiring diagram. Once again, another day's project. Dig in take pictures of the colors on the wires, back of gauges and figure it out. The gauges work, the bezels light up, maybe i am imagining the blue light issue. Although we have an extra undetermined wire on each gauge. I did about 12 hours over the last three days without any problems and the boat is running pretty good. But we all know how that works...

    1995 2335 Boat alarms Temperature and oil

    Duane, That was pretty helpful. I have had the boat about 12 years and don't remember any alarms. As discussed previously, twice I remember the dashboard lighting up with blue lights on the gauges momentarily during daylight hours. The bezels light up at night normally with the navigation lights (if that is normal) I have a feeling I may have a wire off or open ground somewhere. As discussed with Wing Nut I have to dig into this a little deeper. It appears on your boat setup the oil pressure chimes the alarm until you start the engine. (just speculation) and there is no timer holding circuit. The wiring diagram I saw indicated the holding circuit control may or may not be installed. I am hoping to look into this this week sometime.

    1995 2335 Boat alarms Temperature and oil

    Wing nut, 1995 2335 Chaparrel 5.7 Mercruiser with Alpha One Generation 2. Quicksilver single station controller. I have a Sealoc subscription and they say ground out the wire to the water temp and watch for upscale activity. (it pegged) Maybe I made an assumption if you ground out the "over temperature wire at the thermostat the alarm would go off as well. I now feel guilty for bringing this to the blog without doing enough research. I was really looking for a supplier of the buzzers and/or buzzer controllers. I need to dig deeper in the dash board, and figure out which wiring diagram is correct for the installation. The gauges work with the key on and the emergency switch on. The gauge lights work with the navigation lights. I mention in a previous post about twice seeing blue lights on the gauges (during the daylight) and it goes away. These appear to be different that the night illumination of the gauges. Sorry for taken your time. I feel it would be a little more appropriate to look for loose or broken wires. high impedance ground connections and compare it with the correct diagram in case the wiring has been hacked as Soldier 4402 indicated. As always, Thanks for being there. Allen

    1995 2335 Boat alarms Temperature and oil

    Wingnut, I guessed on the oil pressure sensor. I started with the Water switches by grounding them out. No alarm. I saw the oil pressure switch on another post somewhere and kinda remember seeing a typical oil sensor on the block, just don't remember what side and did not test it. Sorry if I mislead you or anyone else. Trying to start with one warning at a time. I figured if it is buzzers they would be common to water and oil. Someone else mentioned, disconnection because a nuisance. That would be another to follow up as well if someone joy rigged it. I'll get in there under the dash in the coming days and cut all the wire ties so I can figure things out. I have a wiring diagram if it is the correct one. I am electrical contractor/inspector this should be electrical 101 but nothing in a boat seems easy. I have worked on lots of stuff in my life. Working around that 5.7 Mercruiser is all cameras, mirrors, and mostly "feel" The motor is really stuffed in there. Half above the bilge half below and half of engine under the extended plane portion of the boat. Another issue, I noticed on a rare occasion (twice) I was getting blue background lights on gauges. It was during daylight hours. The gauges back ground light work at night. Does anyone have lights on the gauges that work during the day with the navigation lights off? I like these blog sites, lots of knowledgeable people, and certainly lots of "hard knocks" education. Best of wishes,

    1995 2335 Boat alarms Temperature and oil

    Well, You can see the two buzzers in picture. Water wise, I have a sender to gauge and a alarm for over temperature. Both sides of the thermostat housing. Oil pressure is down near the starter. I noticed nearly all the boats in the marina have a short blast of under 10 seconds when the key is turned on. I figured the buzzers could not be much more then 20 bucks each and pretty easy to change out once I cut all the wire ties holding them in under the dash board. Gauges for Oil and water temp working. I am not sure if one is a buzzer and the other is a timer/buzzer . I guess I got to remove them to see what the heck I got....
  24. Gentlemen, More school of hard knocks. I took the lower foot off the Alpha one. I used a lot of Silcone (Ultra Blue permatex) There is a small casting wall between the rubber dam and the casting needed some filler in the corners. (Right side of picture) This is where it was sucking air at 3200 rpm's The clear hose really defined the problem to the outdrive. Problem solved and a little smarter.
  25. Hi Everyone, Looking for some new ideas; 5.7 Mercruiser- Alpha one generation 2 overheating above 3000 rpm. I have doubled checked the seawater pump, changed the 3/4 hose between outdrive. Checked for obstructions in Y pipe and outdrive, replaced shutters. Furthermore I have back flushed the PS cooler, Replaced thermostat (Will remove soon) I back flushed the engine with the circulator pump off and replaced the pump. The exhaust riser were taken off and cleaned with special rust eater. It has the restricter gaskets on exhaust riser in which I considering removing I am down to testing the sensor ohms and removing the thermostat. Last outing by myself I measured 150 f on starboard and about 130 on port side on exhaust riser and if my memory serves me correct I had about 150 f on thermostat housing. Goes from 160 to 180-200 F on gauge until I back it down to cool off. Don't want to trash the motor. Any ideas? The motor is fresh water Delaware use and about 5 years old (almost 400 hours) I am at my whits end.
