Yanmar 3GM raw water cooled?
Thanks Glen, I'll check that out.
The point here is weight saving, so he hopes to be rid of the exchanger tank, the additional pump, etc. As the engine is used for battery charging, we will need to install a loop to recycle heated water through the engine, as the raw water in the Southern Ocean would cause the engine to run a little too cool thanks for your suggestion.

If you don't get what you need, ask he http://forums.torresen.com/eThreads/view/engines/ Very good source for info. I used to order all my parts from them before Yanmar in their infinite wisdom decided not to allow me to choose my provider. By the way, make sure you have the model number correct (since it isn't your engine.) There is a 3GM, a 3GM30, a 3GM30C, and a 3GM30F. I'd be mildly surprised if the engine in question isn't a 3GM30F. A quick look at my 3gm30 manual shows that the kit for converting a raw water cooled engine to fresh water cooling contains: fresh water pump sea water pump (don't know why) cooling water pipe heat exchanger (includes exhaust manifold) subtank thermostat assy (hotter stat and different cover) fuel oil pipe assy (different shape, I think) v-belt, gaskets, bolts, etc. so you'll need more than just the manifold. I think you will need to plug the bypass passage as well. Hope this helps. __________________________________________________ __________ Glen "Wiley" Wilson usenet1 SPAMNIX at worldwidewiley dot com To reply, lose the capitals and do the obvious.
