06 21v launch 5.7 Indmar Engine upgrade

[Turbinesurgeon]

Looking for help on improving torque or more power out the hole with riders and a few people on the boat.

Might want to start out with a different prop. That would be a lot cheaper than a engine. The 5.7 320hp or 340hp Indmar Assault should be adequate for that boat.
