I recently returned from a sailing trip and found that my Sherwood water
pump on my Universal 30 engine
had failed putting salt water
in my oil
The pump is driven by the end of the cam shaft. This is the second time it has failed in the same why in 4 years where the seal fails and the sea water is leaked into the oil
This is much more of a problem than the impeller failing or something and the engine overheating
. I get an alarm
if the engine overheats. The solution is also impossible to resolve if offshore
because the oil has to be changed 2 or 3 times requiring about 15 quarts of oil which I have not carried up to now. Also the only way to know it is happening is to check the dipstick and see the overfill of oil. Fortunately this has never happened on a long engine run or it would have filled the crankcase completely I suspect that could have done damage.
This pump is expensive and is made of mild steal which rusts real bad quickly internally. Over all this seems like a really stupid design.
I think I may have seen a replacement or aftermarket pump or kit that could make it impossible for the water to get into the oil pan.
Can anybody help me with a solution. I'm planning to go offshore
down into the Caribbean
and wont to resolve this once and for all. The current
situation is unacceptable and dangerous. Other than that I very satisfied with the engine.
