I had my Mercury Lab 28P Promax worked/fixed by Mark Croxton and went from 77mph on the limiter to 86 at 6200/6300 rpm. This is with a Stroker/300xs/1.75 Sporty solo going fishing at 4300 ft elevation. It prob had more in it but I ran out of lake. I need to change the gear case to the 1.62's and play some more.

Wow!! That's impressive.

9 mph with just prop work is incredible..
This is because he was on the limiter with a slipping prop....Originally Posted by kandkkustomzhydrographics
