My Johnson HD 25 carb is percolating up through the gas shut off needle in the float bowl. Carb is too hot to touch after just a minute of running. Obviously overheating. I checked the water pump and it looks OK however, the rubber fitting on the end of the water tube(?) where it meets the pump is rather rough. Can that be replaced?
I don't see water spurting from the two exhaust holes near the top of the leg, but I did see water come out of the bottom of the power head when running after I removed the head drain plug.
Also, I removed the four bolts under the cavitation plate a few inches above the gear case thinking I could drop the drive shaft and water tube with the foot. It wouldn't pull off. A lot of gear oil leaked out at the seam. Is that normal? Should there be a gasket?
I really need a diagram of the lower workings of the HD 25 if anyone has one.
