Westerbeke 20B Two Impeller change
I recently bought a boat with a Westerbeke 20B Two (18hp diesel) engine (1988).
I am in the process of winterizing it but am stumped at how to remove the impeller.
I have been unable to find any definitive info on how this is done for this engine, and I do not yet have the shop manual (on the way).
It seems, to get at the impeller, I have to remove the oil filter which makes no sense (can't imagine having to do this just to check the impeller).
Or, I have to remove the water pump...but in order to do that, I have to remove the oil filter!
Does anyone have experience with this engine? If so, any advice would be appreciated.
Also, assuming I can even get at the impeller once the cover is off, I am thinking of installing a Speedseal cover, as this would greatly facilitate impeller maintenance.
Thanks all for your help.
It's not whether you're paranoid...it's whether you're paranoid enough.
