I'm sure any marina can recommend someone if no one chimes in.
While in Rye on a mooring we avoided begging our diesel mechanic to make a trip to Rye from Croton-On-Hudson. He patiently talked us through Changing Filters, Emptying out our full diesel tank and replacing it with clean diesel, bleeding all the air out of the system from primary filter-lift
pump-secondary filter-injection
pump-injector. This took all of Monday and 14 launch trips to go get stuff. I no longer fear my 2QM15. I think I can do that changing filters/bleeding stuff now in 30 minutes.
What seems to be the trouble?
