Hi all,
I have a 1976 Egg Harbor with the original motors. its fresh water cooled and under the heat exchanger there is a "water distribution tube" that takes the raw water from the exchanger and spreads it out to the risers. There is one big hose on the end 1,1/4" I think and then 2 3/4" tubes on each side. Does anyone know where I could get a replacement? Or do I have to fabricate one?
Thanks,
Jay |

You might try Seakamp Engineering, Inc. 800-753-4436 e-mail [email protected] They build heat exchangers and could probably make you one.
I would think any good radiator shop could repair your old one a lot cheaper. |

A heat exchanger acts like a radiator in a car. This is for a closed cooling system, not a fresh water system. The distribution tube is a copper tube that is mounted inside the exhaust manifold at the lower rear. It is supposed to help remove hots spots in the manifold by bringing the cold water to the to (front, which is higher) of the manifold and at the same time warming the water a bit before it actually comes into direct contact with the manifold to reduce thermal shock. I have run 440's without distribution tubes, but the entry of the water was at the top (and front) of the manifolds. Water can enter the risers through holes in the water jackets at the rear of the manifold ( in which case you must be certain that the gasket between the exhaust manifold and the riser has cut outs for this passage) or else through external piping.
If you have a heat exchanger the qlycol solution is in a closed loop that is independent of the water circulating through the exhaust manifolds. |
