Re: 1956 Johnson 10HO QD 19 exhaust housing temp

[bob-d]

Following up on this problem. Put a new base gasket on, and tried it on the boat vs.test tank. The exhaust housing under the shift lever still got so hot that it turned the water to steam. I’m at a bit of a loss?
Could the exhaust housing become damaged, where the exhaust stream gets rerouted, since now I know the base gasket is good?
My next thought would be to take the exhaust housing off the powerhead, and check all water passagees. On initial rebuild I installed new impeller and used compressed air to check the water passages through the head. All seemed fine,and water is coming out exhaust hole 1/2 down exhaust housing.
Anyone have any new ideas?
