Do those mods jack the motor and tad and run a bigger prop. And if you going to port your motor your going to want to putt reeds in to get the most out of it. When you mod any motor you need to change multiple thing at the same time to get the most out of it. And if your not racing it putt the 90 on it!!!

For your application, I'd pass on all the time and effort for porting, tuner etc. replace the oval port with a 90 yamaha and your done.

If we are just dreaming here and having a conversation carry on

I second that. It doesn't matter what you do to your motor, I can't see you gaining much. Your boat is probably at the point where you needs a lot more horse power to see any more speed out of it.

Sounds like good advice. Or maybe find another hull that was made to go fast.

another hull might just be on the cards.
I cant see this thing ever getting to 50 mph without dynamite.
