Ongoing Saga and Request for Part Numbers
Update on the pump work. They removed, rebuilt, and renistalled the pump. Looks like I was pretty close to access. They just removed a bolt and pivoted the throttle bracket out of the way. Started up and checked. No Leak!
Headed off the next morning. A mile or so down the river I had coolant vapor wafting out of the cabin. Limped back to the dock. Turns out the yard had damaged the cover to body gasket and it blew out
. Yard went back in and fixed the next day. But now I had a much smaller leak still. About one drop every couple minutes vs. drop every couple seconds originally.
So down the river I go with no issues on the trip. And no coolant level loss when I checked when I got to my mooring (about 6 hours of engine running).
Now confusing part. Original pump is a "2 bolt unit". Mounting flange is "4 bolt". Has not been a problem before since, with gasket, it seals fine to the block.
This is not a Universal part since engine was originally designed as a raw water cooled engine so did not have this coolant pump. I believe this was added by Ericson when the boat was built with the "fresh" water cooled, hot water tank option.
Yard is scratching its head over what the "right" pump is.
Does anyone know what the original Sherwood Pump model for this application was? And was it 2 bolts or 4 bolts to the block?
Those pumps are now obsolete. What would be the current model number for this pump?
