Has anyone painted a whole outboard while still on the boat? I have a 1990 Johnson GT 175 and the paint has peeled in sheets, and is down to the bare fiberglass in spots on the cowl, and aluminum on the lower unit. I'd like to repaint this myself (I have a compressor and gun), but not sure if I'd need to take the motor off. Anyone try painting a motor on the boat? I'm on a tight budget, and would appreciate any guidance. Thanks!
