Krope, the issues may be related. But maybe they arent. Are the bolts holding the heads down SRP or original TTY? (Torque To Yield) TTY shouldnt be reused. There is a chance the TTY bolts are spent if reused and will stretch. Mostly everyone knows this but maybe somebody didnt.

I’m new to the fountain boats, I didn’t even know fountains didn’t come with a speed and marine intake😱
Looking like I have a gen 2 system with a airmotive fuel pump\filter. Did these boats come with that oris that something that was added ?
I wish there would have been a 113 micro filter in front of the pump, and I wish I had caught the 10 micron that was In there. Before I cooked the motor.(2piston and both head gaskets, the boat ran strong 68 mph but now it runs stronger at 73. Mph
