Firslly Welcome to Ribnet!
I have also just bought one of these for days when the rib is just too big!
One thing I would say about your seagull - I had a similar problem with a 1970-ish Johnson 2HP - namely the open cowl & the spray from the main engine's leg being dragged through the water don't make for a happy spark! - These engines were not designed for that sort of life!
Simple answer - a plastic bag & a bit of string! (and a couple of big rubber bands to stop it flapping in the breeze!)
I guess Lincoln could be too far south for a weekend jaunt, but have you seen Poly's S*IB cruise thread?
