I'll try to explain because I don't what you call it. I you are facing the outboard from the front-<br />the large in/or bolt that (as it seems) allows the <br />engine to tilt is VERY rusty. It runs directly parallel to the transom. Is this a solid metal pin?<br />How concerned should I be? The engine is a 1985 140 hp engine. Hard to replace? Expensive?
