7.4 MPI super tune?
I was looking at a 2000 29 Powerquest with twin 7.4 Mpi's they are 100% stock with 35 hours. What can be done less Blowers, to get a bit more top end out of this boat?
Thank you in advance

I have the same in my boat (single) not to much can be done for a differance you can see on a gps, make sure you have the right prop, you could change the heads to the magnum heads but you have to keep the rpms under 5000 these motors do not have the good crank and rods

Zilch. I have one for sale (7.4MPI) - there are loads of used ones out there, the market is flooded. They're very different from the Mag motor (crank, rods, pistons, heads, EFI, etc....) - it would make a good truck motor though 
. It's my understanding that the durability declines substantially if you put a blower on them. .02
