Re: can I resleeve 40hp merc
This is a common problem with the 40/50/60 3 cylinder engines as the sleeve will rotate and pull toward crankshaft if they get hot from weak or failed impeller. When this happens the sleeve will raise up and the top ring will catch under sleeve,this results in top ring land broken off and bottom of sleeve broken by connecting rod. When I repair one of these engines, I pin the other sleeves to prevent this. I have one in shop now that has this problem and will be posting pictures of the rebuild process.....
