Hey just recently bought this 255 hp speedster. When I put it in the water it runs like shit for a while. I have to go up and down the pond for 15 mins or more for the super charger to start kicking in . Once the boat starts working right she's fine for the rest of the day I don't understand it . Last time I had her out she wouldn't even idle kept shutting off. But once again when I got her going and drove it for 15 or 20 mins she came to life . Got me stumped. Anyone else have this problem ?
