Prop selection for 90 HP Merc    HELP!!!

I currently have a 13.75 X 15" pitch Mercury Black Max Aluminum prop on my 90 HP Merc 2 stroke and it will run up to 6000 RPM. I am worried as the engine is rated 90 hp at 5500RPM

If I go to an Apollo Stainless 3 Blade 13.25" dia x 17" pitch SR will that probably take my RPM to the 5500 RPM range I want to be at?

I am not aware how I could do this? But I will research it on the web tomorrow.

Thanks, fredo

Thanks,

I don't plan to but I have a 19 year old son who might!

I think I will keep the 15 pitch prop as a spare..

Now I just need someone to buy a Ballistic S.S. 13.50 X 17 prop for a Johnson Evinrude or OMC that the guy I bought my boat from gave me to put on my boat when he sold it to me. I put it on E-Bay. We'll see if it sells ....starting price is 90.00 I don't think I should advertise it on here.

You could probably put a little cup in the 15" prop and bring the RPM down. gfretwell

Probably close enough.... and don't run it at WOT as an SOP unless you're racing for money.
