Thats good to read. It's a funny endeavor sometimes, but carbs, props, setups all change things, & there is no way to be sure but run. Not about bigger or more as much as what works best. Good Luck on more fun.

Nice little increase. I wonder if reeds would add anything?
Ive tried all kinds of things & conclude reeds would be a break thru. The flat wall reeds are not going to do it tho,tried single & double comp reeds & there's no significant gain so far. On bending out the dampers 1 tweek too far & got a nice top end boost then replaced a piston. Been thinking about a new plan & will share that when some actual work is done.
Here is a good read on the topic.
Several people have tried porting, cutting intake, tuner, reeds and they all do very little from what I have taken from the situation.

Right now I will play with engine height, props and maybe have the props labbed. I am pretty happy with the way she runs now. 16ft boat with top bimini top will never be a race boat but there is a certain satisfaction to having her dialed in a perfect as can be. I love the 31.8 engines and will run them until I cant find any more.
