I agree with the RPM comments. Kind of a need to know thing. Also, check into Turbo 2+2 4 blade props. I had a 20 pitch on my carbed 5.0 202 and it was great. They are a smaller diameter prop than most of the others. It was good for watersports and was as efficient as a 3 blade for cruising.

I tried a Michigan wheel way back in the day on my folks old Larson. I was never happy with their performance. I would not buy another.

I would like some recommendations on props to use to improve acceleration, I don't mind sacrificing top speed to be able to come out of the hole quicker and be able to pull tubes or a skier easier.



I have used Mercury's prop selector but it gave me 17 options and I would like to narrow it down a bit with other's experience.


That is the same prop that came on my 2006 carbed 4.3 BR 180 with a 1.88 alpha(check my signature on web page) not near boat now. Slow to plane but lightly loaded i could hit 51 mph and tickle the rev limiter.

I bought a rev 4 19 pitch and it has great hole shot (pulled up 5 teens skiing). And tops at 44-45 mph and cannot hit rev limiter 4900-5000 rpms top. I love this prop.

Your boat will weigh more than mine and not sure your gear drive or if MPI. You may be ok with the 18 pitch.

Also if it's even a larger diameter than a rev 4 you won't be able to spin it properly. I like buying popular props off CL because of you buy them right you can sell them if you don't like them. I still say the high five worked great on the 180 I used it on. It's a small diameter prop with lots of bite and I didn't lose much I the top end. I don't think that engine has enough to spin a rev 4 that's my opinion Or another large diameter prop.Well I forgot Mark has one so I guess I might be wrong. You might want to listed to him but his gear ratio is different.

The tach will be getting fixed, just a matter of determining why it isn't working.

I will find out one way or another what RPM I am turning, worst case I return the 18p to Overtons and spend an additional $250 on a rev 4.

The prop that is on it now is very slow to plane, if I was just cruising it would likely be ok, but you pretty much have to give it 90-100% throttle and wait for the boat to come up on plane.

I will do my best to keep everyone in the loop.

Buying a prop without knowing your current RPM is like buying a pair of jeans without knowing your waistline!!!!!!!!!!!!!!!!

YOU NEED TO KNOW YOUR BASELINE BEFORE ATTEMPTING TO OPTIMIZE

This appears to be frustrating Mr. Cory. So lets keep making prop assumptions as i kinda like when he gets fwwwwastwated.

PS - Camaro's are for the gays...

Actually, that didn't hurt him. You seen his boat is Teal, right?
