If I understand your theory, I’m supposed to gain a little top end speed at 50:1 because the fuel viscosity is lighter than 40:1, right?

This boat top speed has always been around 42 mph @ + - 5000 rpm’s. Saturday there were two adults and a kid plus all the fishing gear, the max rpm’s I could get was 4500.

Thanks for your expertise
