I purchased a 1994 208 Adventure with a 200 SWS Yamaha outboard. I used it for the fall season last year and put her away for the winter. The tilt motor was rusty when I bought it. Is this some thing that must be replaced? Can I take the motor off with out removing the complete engine? Sandblast, epoxy paint, the motor works fine, Murphy's Law prevails. It will go south at the wrong time. Any ideas? Thanx GW woody
