ok guys looking for some help. boat will be out of warranty in march. so looking at doing some stuff over the winter. I talked to impros and on the yamaha boats they have been uping this set up. the rpms to 8500 and then haveing you send your prop to them and repitching that and adding another prop to it that skat makes. he said it would make the boat pull like hell all the way. probly loose 4mph on top but it wont matter if you have 8 people on the boat or 2 its going to pull the way trough. It still wont go over 8000 rpms on the top tough.

I also tought about doing a fizzle intercooler, dont think ill need the bov since the boat always stays hooked up. Reva air power filter kit and riva manifold upgrade kit.

Thoughts on any of this?

Thanks guys
