Re: what Strendrive do i have
Uhhh . . . like dude . . . uh . . . it's an OMC 800 . . . aka a "stringer" drive because the main mounts are to the stringers, not the transom.

Sorry to say it is "physically challenged", but there are many here that can help you with it. Be ready for some haters though

I had a 400 which is basically the same thing. There are some cool things about them, but they have not been made since the mid-80s so parts are a challenge, and there are some inherent problem areas.
