Re: 1955 Fleetwin, running hot?

quote fleetwin:

Well, the 55 Fleetwin did not have a lower cowl, so the water would have been dumping right out of the cylinder head under the engine cover. Was water dumping out of the bottom of the head or not? Don’t really understand what you meant by “coming from the stem”. Perhaps you can point it out in one of your pictures. I tried to find the part numbers of these core plugs but the 1955 stuff seems no longer online at marineengine.com.
Do you see the bottom of the cylinder head where the core plug should be in your top picture?
Please be sure to order a new OEM impeller along with lower seal parts along with the two core plugs, the gearcase is easily removed now that the powerhead is off.

Apologies, I don’t know the proper terminology like you guys here…I meant the engine cover. There is or should I say WAS no water spilling out there, or at least I never noticed at the time of overheating. There is a possibility that it was coming out of the cover on the right side of the motor. I did a few barrel tests initially before hitting the lake, and there was no leakage then. But maybe when I hit WOT, it blew out from the higher pressure and I just didn’t notice. I am going to reassemble and run it Friday night (after checking the welch plug)

I meant by the stem, that water was coming out at the bottom of the exhaust tube. (the port at the middle of lower section). Not sure what that part of the motor is called…I guessed by calling it a stem 🙁
