100 HP Sea Ray Mercury Engine NEED PROP

[krisnowicki]

I am running WOT at about 5200 rpm doing about 35 The engine is on a bowrider 17' sea ray seville. The boat should do around 40-45 with that much engine and how little the boat is?. What prop can I get to do a better overall performance. I am new to this the prop that is on here is an aluminum and has been chewed up. So any advice would be helpful.

Welcome to iboats.

You might be going faster than the gauge shows. They're not known for accuracy, especially if max on the gauge is quite a bit more than your boat's max speed. A stainless prop of similar dimensions should get you more speed. Laser II from Merc does well on such packages. Your max RPMs are pretty much on target for that motor.
