First of all, I have rebuilt two vintage outboards so far...so I'm beyond the novice stage. Both of these had piston type cooling pumps.
I have a Wards Seaking 1.5 hp model #94GG9003A. I've checked every source I have available and they have an identical number, but with a "B" at the end. Assuming that's close it should be a 1949 or 1950. Cute little thing.
After some initial checks the engine runs very well, with some possible carb cleanup needed. Otherwise smooth and even running little motor. Now the question......With the displacement style impeller used in the Gale engines, does the exhaust have to be below water to assist the cooling water flow (partial vacuum assist)? I've run it in a 10 gallon test bucket at this point and due to the height of my stand, the exhaust is exposed (but the pump inlet is below water). The engine gets pretty hot after only a minute or so, enough that I wouldn't want to keep my hand there at all and I shut it down immediately. I've made sure the passages are clear and the original impeller is in good shape (it WILL be replaced). Completely took the lower end apart and verified all gaskets are good also.
This may be normal if the lower end isn't submerged enough so maybe I'm worried about nothing and just need to put it behind my boat....but I thought I'd better ask first!:redface:

(before running). I tossed that immediately and replaced it with a properly fitting key. At that time I verified the condition of the rotor and that it was rotating smoothly with a good fit in the cavity. There was a small chewed out cavity on the back of the rotor, but it was still soft and pliable.
