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 l

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 Pi

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

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!!

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 e

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?

What is the best prop for my Mercruiser 5.0L? Pitch? 3 by 3, 4 by 3, 4 by 4? My main goal is to get skier on top of the water. I don't care about top speed being that I will most likely hang around 28 mph.

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!!

To the 256 guys with a big block, what pitch props are you running? I'm only pulling about 4400 RPM WOT and topping out at 53-54 on GPS. I'm running a 28 pitch standard Bravo 3 set. The Merc "Prop Selector" tool suggest a 26 pitch in the "elite" series props with 3 blade/4 blade. Unfortunately, they run $1000 herds of deer which is a lot of coin to spend to "try" a new prop. Just curious what pitch other guys are running, top speed, WOT RPM, etc. In the Spring when the water was cold, low humidity, I got her up to 56. But I'd like to get 4800 RPM.

Hey boaters, I purchased a 2006 256ssi with the Volvo 8.1 375hp - f5 duo prop. The boat is a dog out of the hole, plows forever. Top end can hit 45mph (speedo) at 4400rpm. The motor seems to be running strong. Anyone else experience this?
