I have had this motor for years. over the last couple years if I run it hard across the lake it will start squealing at an idle like a dry bearing if I get back on it the squeal will go away under load then come back at an idle.
once it starts squealing it will do it all day. if I take it out a few weeks later the squeal will be gone until I run it hard again.
Any ideas ?
