Ok so I have a 1990 Donzi 16, OMC drive, Ford 302, 2 barrel motor...it is totally stock and I want good all around performance and some wakeboard pulling. Recommended RPM in the owners manual is 4000 - 4400 RPM.

The prop that was on the boat when we got it is a three blade stainless steel prop

Stiletto 20-321-01421 14.25 inch X 21 pitch

I also have two other props

OMC 391290 15 inch X 17 pitch
OMC 391200 15 inch X 17 pitch

And also have the chance to get a 15 inch by 15 pitch OMC part number 174926

I appreciate any and all help!

Thanks, Tim

What is your WOT RPM now with the 21? I had a 21 on my 90 16 with a 302.

I am not sure offhand....thinking I should stick with the 21 pitch for now?

I am running a 21 Vengence on my 16 with a 5.7L 350 260 Hp Merc. After trialing SEVERAL other 3,4 abd 5 bladed wheels. 19 -23 pitch.
The Vengence gave me the BEST ride, handling, hole shot and mid rangesthrottle responce and general over all great performance. I am running nearly a 56mph and 48-5100 rpm pending conditions.

My Stiletto 21 has a couple minor dings, so I think for now, I will drop it off, have it trued up

thanks for the recommendations!

Here goes my salesman post :)

I don't know the dimensions on the Stiletto but I have two props in the FS section that I ran on my 16, one is 14.75 and is a 21P, I picked up about 2 MPH going from a Turbo 1 with this prop.
