In my Top Gun I have 2 x 450 Mercruiser with Bravo One , I have 2 propellers set , one 4 blades an one 3 blades.
In salt water , wich one you suggest ? 3 or 4 blades ...or more...??

That year and power likes to run with 4 blades.

I have a 95 Top Gun Kevlar full cabin with 500HPs and Bravo 1 drives . I run 26" Bravo 1 4 blade props at 5200 rpm gives me just over 70 mph and no trouble getting up on plane even with full fuel and 6 people on board . Seems to be a great set up .

But you have 100HP more than me !

hp500s are 470 at the prop. 500 at the crank. the pic. of your motors looks like 500s. you didn't say what three and 4blade you have.

I am running 24" 4 blades on my Cafe' with 500's.
