  1. Another noob - 2002 Chap 186 SSi with a 5.0. I'm looking for top end speed. I went to the online prop selector and what I don't know is the gear ratio of my out drive. How can I find this out? Or does anyone just have a good suggestion for me to use? Thank you!
  2. I’m new to the forums but been reading a lot of good information but thought I might throw my situation out there and see what you guys had to say I recently bought a new 21’ Thunderjet Luxor OB OS (aluminum hard top fishing boat) with a new F200 Yamaha Outboard which has a recommended WOT of 5000-6000 rpms. I bought it at sea level and brought it up to 6500 ft. elevation (elevation sucks). So I have playing with props. I am currently running an aluminum 13p x 16” prop getting the motor broke in. I installed trim tabs to help plain out. It runs at 5800 rpm at 34 mph at WOT. I would like to go a pitch up and get a little less rpm and help with fuel and change to a stainless prop. I know changing a pitch should drop about 200 rpm but if I put a 14p x 15” Solas HR Titan prop (about the only 14 pitch I can find that will fit it) how much will a lil small diameter stainless prop change the rpm. Like I said I’d like to run around 5500 rpms. Its a fishing boat that I want to get from point A to point B as fast and best fuel mileage I can. My other option is a stainless 13p x 15 5/8” Solas New Saturn prop. I seem pretty limited on prop selection at that low of pitch. Thoughts and opinions?? Thanks
  3. I bought this boat in July 2015. I had a mechanic recommended to me by several friends check it out stem to stern. We did some basics (oil change, service outdrive, a few switches and bulbs that needed fixing, etc.) but all in all he said everything was in very good condition. Since then my kids and I have had a lot of fun on it without having to do much besides basic maintenance. I've made a few newbie mistakes and well, I guess my prop has paid the price for a few of them... Last time we were out I noticed a bit of vibration and upon inspecting the prop I can see it's taken a fair amount of abuse. I don't need to put it on a balancer to tell you its out of balanced. I'd include a picture but its too embarrassing... I'm going to replace it, but I'm not sure if I should just replace it with the one that's on there or if there is a better option? I tried a few of the "prop chooser" tools online but I never seem to have enough of the data they need for a full recommendation (for example, I have no idea what the boat weighs...) The prop that's on it now is a 48-832832A45 21P. It's aluminum, which seems to be where I'm leaning vs. SS... Anyone know if this was the prop that originally came with this setup or was it something different? My inclination is to simply replace what I've got with the same unless anyone has some kernel of wisdom or a recommendations they'd like to share. Any info or suggestions would be greatly appreciated.
  4. Hi, newbie here. Just purchased my first boat, a 2017 21 H2O Ski & Fish OB. We went with the 150HP Yamaha. Supposed to be ready before Memorial weekend (I hope!). It comes with a stainless steel prop. We'll be using the boat to pull tubers/skiers, fishing, & general cruising with the family. It will be used at our cottage on an inland lake, which has a rocky bottom. Wondering if a switch to an aluminium prop would be a good idea? I realize I may be sacrificing some performance, but if I run the bottom, I'd rather ruin a prop than the whole motor... What do you guys think?? Appreciate the advise, & can't wait for it to warm up here (Michigan)!!
  5. Does any one know what prop would have been on this boat stock? 5.0l Carb Alpha one out-drive
  6. I want to replace my current aluminum factory Mercury propeller with a stainless propeller. I am not looking to upgrade or change performance because I am happy with the current time to plane. If anything I would select more top speed over hole shot. Here is my boat's configuration: 2004 Chaparral 215 SSi Mercury 5.0L with Alpha 1 Gen 2 (320 hours) 1.62 Gear Ratio Current Prop: 14.25 x 21P Can anyone please recommend a suitable replacement Stainless Steel Propeller? I tried to use Mercury's Prop Selector site, but it recommends Diameters and Pitches that I don't believe are relative to me keeping my current overall performance. Here's what the Mercury site recommends based on my boat's configuration: Propeller Material Blades Diameter Pitch Rotation Part # Enertia® X7 Alloy 3 14.2 18 RH 898996A46 (NOT USED) Enertia® X7 Alloy 3 14 19 RH 898998A46 Revolution 4® Stainless Steel 4 14.625 17 RH 857024A46 Vengeance® Stainless Steel 3 14.5 17 RH 16314A46 Vensura® Stainless Steel 4 14.5 17 RH 825898A48 All of these propellers have lower Pitch numbers which if I understand Pitch correctly will give me better hole shot performance, but my top speed suffers. Thank you for your time. Jake
  7. Hello all, I currently have a 2004 Chaparral 204 with a 5.0l mercruiser alpha. it has the standard Mercury Quicksilver 14 3/4" x 21" three-blade aluminum prop. The poor boat is a total d-o-g getting out of the hole. I ma dragging forever and a day....... Top speed is around 45, i don't remember rpm but not maxed out. I've been researching props and there are so many different opinions which I understand. But I would like to hear from some of you who have switched out. Any feedback would be appreacited I'm thinking stainless steal 4 blade 19 pitch... but going from a 14 pitch to 19? is that too crazy? I've seen comments about Hi Five & Rev 4 and I understand the reverse and top end speed issues. I'm ok with losing some mph but I would like to keep a good reverse because it seems like I don'y use reverse when in a situation I want to get out of rather quickly. I also would like to get a good price. any suggestions on where to buy online?
  8. So i've been on a sharp learning curve the past few days since becoming a first time ski boat owner. Thanks to all here who post, ive been all over this site soaking in your knowledge. I now understand prop pitch, rake, cup. My 220 has a volvo penta 5.0 with 1.51 outdrive i think, with a 14.5", 19p aluminum prop. Had her out once, didnt run wide open but wasnt sure what the wot rpm's were then. learned volvo says 4600-5000. So we did about 47 at 5000 ish. Id like to replace my prop without reinventing the wheel. If i decide on a certain size and pitch there is still a hundred to choose from. So if anyone can share what prop they use for my similiar setup and how it performs i would love to hear it !
  9. I have a 2007 Chaparral with a 5.0 GXI engine. I thought I've been having an issue with the throttle only switch breaking but I realized the switch isn't disengaging. So in short, when I move the throttle down, the boat believes I'm only revving the engine and doesn't spin the prop. I took apart the throttle to see what the issue is and there is nothing wrong. The little plastic button isn't broken, nothing's wrong with the wiring, it just doesn't disengage. Is this some sort of trigger being set off for safety reasons? If I jiggle the throttle too much, the switch comes so far out that I can't even move throttle down or back. Any help would be greatly appreciated as I don't want to spend hundreds for a simple fix. Has anyone experienced this??
  10. Looking to see if anyone out there has any experience on selecting the prop pitch for the Sig 350 (formerly the 330 before 2011). I have twin Merc 5.7 Mag 350 Bravo 3 and am using stainless 24 pitch props (came with boat). I am thinking of lowing the pitch slightly to get on plane quicker. I'm ok when the boat is not heavily loaded (just 4 of us) but once i add a few more people it obviously slows me down. I notice that many other cruisers of similar size that i ride in have little issue getting up on plane with the same 5.7 engines and 12 or more people . For me it takes a lot more time just to get up on plane. It takes the engines some time to spool the RPM's to the 3000 plus range i need to get onto plane. I know there are a lot of other factors such as weight distribution. Good news is the boat has tons of seating with both port and aft seats near the rear of the cockpit bad news is does put some additional weight to the rear. I actively manage the trim tabs but its still not enough. I am looking for advice on what anyone else with this boat or similar has done. Thanks for your help!
  11. Hello. New to the site and new Chaparral owner. I have a new 21 foot H2O. love it!! I am looking to put a new stainless steel prop with a different pitch to give me more out of the whole shot / pulling skiers, etc. I know going to a 19 or 21 pitch would help. I don't mind losing top speed. Wondering if anyone has any advice / knowledge on the best set up for this - 3 or 4 blade, right pitch, etc. I have the following engine: Mercruiser 5.0L 1.62 Gear Ration. Alpha 260HP Thanks in advance for your help!!
  12. I have spun two hubs now in my prop. (Boat: 2000 Chaparral 245SSi Merc 5.7 EFI Bravo 1) Went to the prop shop again today, they advised me that I had the incorrect prop/pitch on it and that is why I keep spinning the hubs. The prop that was on it when I purchased the boat (two months ago) is/was a Turbo three blade stainless 22 pitch. The prop shop told me based on their book, I should be running at WOT 4800-5000 RPM. With the 22 pitch I am only running 3400. I now have a new 17 pitch four blade aluminum prop (Diameter 14.5) that they recommended (have not installed to test yet). What is everyone thoughts? Suggestion on the pitch/number of blades? Thanks!
  13. Okay wisers - after a little over half a season running with trim tabs, I seem to have more occurrences of prop blowout in turns than I had pre-trim tab days. Is this to be expected and what are you doing to minimize it? Should I be considering a prop upgrade? I am running the factory Bravo Three 24P 4/3 props that came on the boat. Thanks in advance....
  14. I was wondering if anyone had any experience or prop recommendations on a prop upgrade for a H2O 18 3.0 MPI. I have seen several post concerning the H2O 19, but very few on the 18. I believe it came with a 14.5X19 Black Max. I would like to go with a SS prop as I am very rarely in any shallow water, and do not have any stumps to worry about. Wanting an all around good performing prop. We primarily pull kids on large tubes, but my wife and I also wakeboard and ski a bit.
  15. i have a 4.3l LX mercuriser engine with a 3 blade SS 19p vengence prop. My buddy asked me about my WOT RPMS and he said i have the wrong pitch. WOT is 3600 RPMS plane / cruise 2800 RPMs roughly The engine was replaced in 2010 i believe with a new one. i read online my WOT should be around 4400-4800, and each inch down gives me 200 RPM? Should I run a 15 or 16p prop on my boat to fall inline with the engine requirements?
  16. I have a 2008 190 SSI with a 4.3 220hp Volvo Penta, with a 4 blade 19" 14.25" prop. I want to increase the low end performance to get on plane easier and quicker. Would changing the prop to a 17" (or even lower) SIGNIFICANTLY improve the low end performance. I'm OK loosing some top end performance. With 4 or 5 adults on the boat, it is hard to get on plane (even with 2 of them in the bow). Would this create any issues or overload the engine? Would a stainless prop make much difference. Any suggestions or experiences from others who have the same boat?
  17. I'm looking to upgrade my prop. Currently, I've got a 21 pitch Mercury Black Max 3 blade mounted. I had a 21 pitch Vengeance reconditioned and mounted on the boat, but found similar performance to the cheaper Black Max. 4 hours after the $170 reconditioning, I smacked the Vengeance on a stump - I don't boat on that lake anymore. Everything I read about the Enertia seems to be favorable and many have praised it against the Revolution 4. I was settled on picking up a Rev 4, but I hate to give up the top end - I love seeing 50 mph on the GPS speedo at the end of the night ... I do an equal mix of putting around the lake, watersports, and some high speed runs when trying to get to the glass bay. Any Enertia users want to chime in? If you have recommendations in pitch vs a 21 pitch Black Max, that'd be extremely helpful …
  18. I recently purchased a 1987 Chaparral 198XL that needs restored. I would like to get it running and on the water this summer and then work in the fall/winter to get it restored. It came powered with a 5.0L V8 with an Alpha One drive. The prop that is on there is dinged and bent pretty well. Does anyone have a recommendation for the right prop to put on this boat? I'd like to ski behind it, so pulling from a stop is more important than top end speed to me. Thanks for the help!!
  19. If you own a 190 SSI. What is your favorite prop and what dia/pitch is it? Thanks, Jim
  20. The body shop I work at fixed up a crack and painted the side of a 226 ssi for a customer. It took a long while but we got it all done and ready, but in the process of putting the canvas back on the top of it, a prop bar for the back canvas fell (only about 3 feet) and broke. The part that broke is the clamp that you undo to adjust the prop rod height, it snapped in half. I really need to replace this for him because He just bought the boat and its in brand new condition. I've looked around and the only thing i've found is you can buy a whole new canvas for the boat for around $950. The question is, does anyone know where I can purchase a new clamp or prop rod as a whole for a 226 ssi? This is incredibly urgent. I'll upload pictures tomorrow if this isn't answered.
  21. For general all around purpose, pulling tube, sking, cruising what is the best prop size and pitch for a stainless prop on the 1830 SS with the 4.3l?
  22. Good morning all, this is my first time posting on this site. I'm picking up a 2004 chaparral 230 SSI this Tuesday. It's a creampuff of a boat, has low hours (160) on a mercuiser 5.0, I can't say enough about how well the previous owner took care of his toy. The outdrive is a bravo one with an aluminum prop which seems to be a little underpowered to me. The previous owner installed a stingray hydro fin which helps get on plane much faster with 4 people and a full tank of fuel. I'm thinking of taking the fin off and installing tabs, as the boats layout creates more of a port list due to the seating arrangement. What are your thoughts about: 1. Adding tabs and removing the hydrofoil? and/or 2. 3 bladed stainless prop vs. 4 bladed prop or should i just keep the aluminum prop on? I don't care so much about top end as I do a quicker hole shot or slower planning speeds. 3. or a combo of both? I have read that the hydrofoil and the four bladed props will decrease top end speeds, how much, not sure. I grew up on Chaparrals from my father's 19 footer to a Signature 30....wonderful boats and now I'm proud to say that I own one. Thanks in advance, Big E
  23. I Have A 2005 190 SSI, EXTENDED V PLANE With A 4.3GL-D Volvo Penta SXM 1.79 Outdrive Any Suggestions On A Prop. Upgrade To A 4 Blade Prop? It Has a 14x1/4x21 3 Blade On It Now.
  24. 2003 180SS 4.3L (Carb'd) has a aluminum Quicksilver 1918P21 (21 pitch) on there now that's a little worn and dinged up. see pic. Engine WOT RPM is supposed to be 4400 to 4800, but I'm hitting 4950 or so at a little past 3/4 throttle. If high put the hammer down, the engine will buzz up towards 5000 but starts to miss a little. Governed? Just a little over rev'd eh! I'll get about 55mph at around 4950. Using the prop selector at Quicksilver I get a few choices. see pic. One route choosing overall performance gives me the group of 4, and the top speed route gives me the 1 choice. Playing with the WOT in the chart to 4900 shifts the 4 props that are shown, to show 1 different choice. I'd like to get stainless. Currently the boat yanks out of the hole and is on plane very quickly. I will be pulling skiers, tubes, kneeboards and such. The current beat up 21p does good at that but engine perf. isn't to par. I friend on the lake said he used to have a dinged up prop and was getting into high RPM trouble with his 21P. He put on a brand new same prop 21P and it fixed his RPM troubles and got about 5 more MPH. Another boat buddy had a alum. 15P on his outboard and went to an alum. 17p but was a dog out of the hole. He switched to a SS 17p and now can about pull out of the hole like his alum. 15p but got some top end along with it. I'm thinking a SS 23P around 13.75 dia. (Lightspeed Prop) comments? advice?
  25. I just bought a very nice condition 2002 216 SSi, which incidentally has the same hull as the 220 SSi, so owners of that boat please weigh in as well. It's powered with a Mercruiser 5.7 EFI with Alpha Gen II drive, swinging a 3-blade Vengeance SS prop, 14" diameter and 19" pitch. With a moderate load, it will top out at about 51-52 mph at 4,800 rpm, and we operate at Lake Mead, with an elevation of 1,100 feet. The hole shot and low speed planing of this boat are not quite what I would like. I am happy to sacrifice 5 mph top end speed for better low speed acceleration, planing control and tight turns. I have looked into both the Revolution 4-blade and the High Five 5-blade props. Does anyone have some experience with either prop, and if so, what do you think is the better overall compromise? We mostly do cruising, towing inflatables and wake boarding. Many thanks guys Paul
