I have an M-12 two-cylinder 10 HP Universal Diesel inboard motor in my 1984 ODay 28. I replaced the fresh water pump 4 years ago. I replace the sea water impeller every year.
I went to order a replacement impeller (301339) for the fresh water pump (UNV-301336). I'm told that is an obsolete part that I can only get as part of a complete replacement of the fresh water pump. My questions are:
1. How often do most boat owners change the fresh water impeller?
2. Does anyone know where to get this part?
I'm a sailor so the motor gets only modest use starting and end a day of sailing. Last year I moved from Maryland to New Bern NC which entail quite a bit of motoring in the ICW.
