When motoring our 89' 37 Legend and engine RPM is between 1100 to 2000 there seams to be a vibration, greater than 2000 RPM it smooths out. Has anyone else had this problem?
I have a '88 L37 and a few years ago mine developed a vibration at low RPM. I had the yard check it and it turned out to be an alignment problem. The yard adjusted it and it was fine.But first be sure that nothing is fouled on the shaft or prop. Check for barnacles or growth on the shaft/prop. Make sure your zincs (if you have any) and not loose. Good Luck
