I had not thought about a bow thruster. That would explain the heavy duty construction
and salt water tolerant material. Gear case has no provision for water pump nor does
it have a skeg.
I can not post photos but can send for posting.

Looked up Sleipner Thruster, mine does not appear to be a current product. Company has been around since before Model T Ford. Apparently making engines only until 1978.
So thruster is a classic not an antique by aomci standards.
It sure did look like an old outboard lower unit. Good thing I only paid pocket change for it.
Will take to next swap meet.
Thanks
