Re: Need help identifying outboard
I was told that this is a Hiawatha, but I haven't been able to verify that. On the block there is stamped 463 43755. Any help would be greatly appreciated!
My Intertec manual Hiawatha data starts at 1955 and I suspect your motor pre-dates that time. The '55 (and prior?) motors were supplied by the Gale division of OMC. Scott/Mc Culloch assumed the contract @ 1956 or '57.
Ii can't help wondering if the #s you found are casting #s rather than model or serial #s. If cast in place they are probably casting #s. If stamped they are probably model/serial #s. If it's a Gale/OMC built motor it SHOULD (but not always

) have a 'freeze-plug' with the actual model # stamped thereon if you are unable to find it elsewhere.
The transom clamp brackets look like Gale parts but the lower leg/lower unit look like something else. The space in the front of the top of the gastank looks like an early 50s Gale pullstart assembly would bolt right on. Strange! Keep us posted on what you discover.
