Chris T - any hint on a source for this rubber cap?

Certainly this is not a stock installation as came with the boat. The exchanger contacts the galley cabinet at the side, and rises above the level of the engine cover. A PO has added some plywood pieces to make the engine cover stick up an inch or so. And it does have to come out to get access to the carb.

Looks to me like there's plenty of real estate to mount the heat exchanger on the back wall of the engine compartment, as long as it clears the shift lever. I actually love the engine access on this boat (ericson 29) which is one reason I bought it. The engine cover forms part of a double-wide quarter berth, which leaves plenty of room around it. If only the heat exchanger wasn't blocking the carb, there would be no accessibility issues at all.

Re: the twins - both engines are installed in 70's era Ericson boats.

I just purchased a 67 Triton with the same freshwater cooling system. The raw water pump and mount has been lost, hope something can replace it. The cooling exchanger is mounted in one of the cockpit lockers, Open the lid and the tank is right there, so I'm assuming mounting out of the engine bay and up high is an option.

Any reason why slightly longer hose runs would be a problem?
If you attempt a repair of the existing exchanger I suggest completely 'rodding out' the tube bundle prior to reinstalling the end cap. There's no better time than now. Also, plan on pressure testing your repair on the bench (I did with mine and it was a good thing). It's no fun chasing leaks on the boat.

Relocating the existing exchanger is no problem provided the fill cap is at the highest point in the system, water heater (if fitted) included.

Carl -
Regarding your missing pump and bracket, there are several of us running successfully with an electric coolant pump. It's a relatively new concept but it's one of your options. We're using the engine mounted pump for raw water and the electric for coolant.

For the record, if anyone stumbles across this in the future, the horizontal heat exchangers discussed above were made by "Sen-Dure" in Bayshore N.Y. A quick google search shows that the company has moved to Florida, but still makes such items. But I attempted to repair the existing unit.

I stopped by the boat Friday, on the way to a job, and brought the offending parts home with me. The part that was up against the cabinet had an ID plate that was revealed by stripping off some old paint with a bit of Goof-Off.


Everything seemed to be made of copper or bronze, so I cleaned up the parts and soldered them back together. I had a bit of trouble keeping the big part hot enough with a propane torch, but I hooked the finished item in to the kitchen hot water loop while I ran the dish washer, and it didn't leak. The gasket under the inspection port was worn-out silicone. Couldn't locate any silicone sheet around here, so I cut one out of red rubber as a replacement. Spot of new primer, et voila! Chuck it in the "to the boat" box.

I too have a C&C 33... I hate working in it most times, can't reach anything when it comes time to work on it.

In the process of replacing my old heat exchanger and I'm thinking of mounting mine ahead of the flywheel.

Good on you for mounting it on the side
