I'd like to know your secret in getting 39 knotts out of a 100hp on the 6.2 please?

As a bare boat with no stainless on, no seat bases and minimal equipement the fastest I had was around the 42kn with a 21" Viper on. But with all the kit on board, full tanks, stainless etc I can reliably get 38kn's using a 19" Viper prop.

I'm more than happy with the performance, but always thought it should have acheived just over 40kn's. I'd love to try a 17" prop and see what that does as there's another 250rpm to max out WOT

With a piece of kit I'll be recieving soon, I'll be able to tell the outboard it's a 300hp and get over 60kn's

37kts I'd guess.

Quite possibly!

However after I started adding weight the performance of the 21" dropped down to 35kn's and started to bog down when accelerating. It was funny as WOT didn't seem to reduce with the speed, indicating more slip was to blame. I clawed the speed and acceleration back with that 19" viper you found for me on ebay and it added 250 rpm to the WOT which is now midrange at 5000 rpm. I've always been curious what a 17" would be like, but I haven't found one at the right price.
