I've got a 1986 85 hp force outboard. I have a cracked lower motor mount. The guy I have taken my boat to for repair in the past says I need to replace it right away because it may break my upper mount(s) and he said you can't get them any more. Anyone have any advice for replacing the lower mount and an idea if and where I can get top and bottom mounts.He wants $350.00 to replace the lower and I don't have it.<br />Thanks
