rigging genset westerbeke

[wrench]

 I got a westerbeke 15.0 BTD= 15Kw diesel marine genset, engine (may be perkins)  1987-90, show 1600hrs. I want to set it up for home backup & I worry about if I run the exhust in a water tub(for muffle purpose) with the coolant re-route to a radiator & fan & shut the raw water. Will the exhust get too hot without the water injection at the manifold outlet? (will remove impeller in raw water pump).
            Any input?  pitfall?      thanks

Can you replace the exhaust manifold with a non-marine one?

Then it'd be easier to run an exhaust stack above the roof of the house to minimize CO problems.

You can run the hot side of the radiator water through the exhaust manifold then into the radiator-but that creates a lot more heat for the radiator.  Unless you need a cooled exhaust manifold, the previous suggestion to get a dry manifold is the best-then wrap it if it is still too hot.  (Probably is a Perkins 4-108) Good Luck, TomC

wrench, tie the manifold into the radiator the marine generator has been used for years in conversions using the water cooled manifold with no problems I know you are using your for a different purpose but I have one in my coach with a radiator and the bay stays cool with the water manifold    good luck

Don't know exactly what you situation is in connection with the installation but one way that is usually overlooked is city water cooling. It works well with a Marine system in that it will cool the sealed water system and that water will then cool the manifold before it's wasted.

If you have a large pool or creek on your place that would work as well.

As far as a muffler is concerned you can take the dry exhaust and put it through a dry muffler. You've now satisfied all the needs...cooling the heat exchanger, the wet manifold and sent the cooling water to waste making your exhaust dry...with no radiator or fan, which Marine units aren't made to accommodate anyway.

If the Westerbete is a universal type generator cooling through the radiator works fine with water manifold for years the high end converters like Marathon, Liberty and Bluebird used the universal type made by Medalist in Oshkosh WI I had 2 in different coaches with the units never a overheating problem the only difference I can see is the raw water pump and I wish I had one now instead of the thing Onan calls a generator 1000 bucks for every hick up  have a great day

  Thanks much for all input,  will retain the marine exhust manifold for sure.  I beleive the engine to be a 107CID by the specs I found, was not sure about the manufacturer probably perkins.
    Thanks again all.         wrench
