Hi all! New to all this so please bear with me.
I purchased an old sea start 15’ tri-hull with a 55 hp Chrysler on it. The motor is a 71. I’ve had it running a short bit and so far most is well. I changes the impeller for the water pump and here’s my question.
The pipe from the impeller housing up came out with the lower unit. I’m trying to figure out where it connects up top. I honestly don’t think it just goes up and connects to nothing. The manual doesn’t specify anything about the pipe so I’m kinda lost. Any help would be great. Thanks !
Well, if it doesn't connect to anything, you're not gonna get water to the powerhead!
I was looking at a diagram for a 1975 55hp (the oldest year I could find) at
and the pipe is smooth on both ends. At the bottom you've got a rubber grommet in the water pump.
At the top, it appears to have an O-ring that the tube slides into, and a flat washer, which I would imagine serves as a "stop" for the tube.
I'd bet if you look upwards at the inside of the exhaust tower with a strong flashlight, you'll see a hole for the water tube. It'll probably be on a side. I was also looking at the gasketing for what they call the "Leg" aka exhaust tower, and there's a round hole on the side of both lower and upper gaskets, that looks like it's about the right size for a water passage.
Actually I did find it. The tube curves and it was off to the left side. It was actually harder to get the lower unit connected after it was hooked to the power head. Still haven’t ran it yet to see if all is well, that’s later today. Thanks for the response
