I got the 4 cyl 240HP. Powel said that he just put it in a boat this summer and that the guy overheated it. The guy is getting a brand new replacement. So Powel is completely going through mine by sending out the head and turbo ect.. Will be like brand new when he is done and still under the origional warranty! Think that he said that it only had like 40hrs on it before it got hot and that the guy shut it right down. I saw the block on the stand. The head and turbo should be back any day now. I have been wanting to convert to diesel ever since I got this boat. Getting this motor is a "GODSEND" for me.
