Well Guys my bad luck with boats continues :( Took the shockwave out this morning, started fine sounded really crisp and not noisy at all, ran it up and down just to check that the cooling system was working, took a little while to see the water come out of the outlet, but when the boat picked up speed it was comming out about 6 inches so thought it was OK. Well turned it around and opened the throttle it just started to really move then spluttered and stopped, guessed it might be a little lean because of the pipe, no problem we will richen it up a little. So got the boat back altered the mixture and tried to start it but guess what no compression ! what the hell happend there then? I am completely gutted once again I have spent hours on a boat going over every thing just to go over the lake and come home without a run. Bought a new piston ring this afternoon, plus ordered a water pump that runs of the carb, has anyone any Idea as to what went wrong ? it could not have got that hot there was a good jet of water comming out the side, maybe the ring juts broke or there was something in the engine that wore it out, I dont know, will take it apart this afternoon and have a look.
