I just purchased a boat for next to nothing and the guy told me he took it to a shop and was told there was no compression in one of the 6 cylinders. Well I bought it anyway and have been trying to get in touch with repair shops which are not returning my calls. So I am turning to you all for help. My question is what could be the reason it has no compression? I have been told I will have to change the power head, or my head gasket is bad ,and it could be my rings are bad. Either way I dont know. The motor runs fine at idle for a while then will sputter but when I throttle it up it doesnt sputter and runs fine. I was told at an idle fuel was building inside the down cylinder and when it ignites it sputters and when I throttled it up it was burning the excess fuel off so thats why it wasnt sputtering at high throttle. I dont know if thats the case or not it could just be bad fuel. Anyway let me know what you all think so when I do get in touch with some repair shop I dont sound like a complete idiot and they charge me for something that I dont need.
