About six months ago I noticed water not emanating from the exhaust thru hull for my 2GM20F Yanmar engine. So I took the raw water pump to the local yard and found the shaft turning but the impeller sitting idle. I had a new impeller installed then and afterwards,as usual, started the engine and ran it for 20 minutes once a month to keep every thing moving.
On June 13 I went on cruise for a week to St Augustine with the engine being used 6 hours a day with no problems. But yesterday when I started the engine again, no water came out.
The thru hull is and has been clear of obstructions. Volume of water when running normally is quite normal. The hose is less than a year old. The mech thought it had been run "dry" (how I don't know).
So, Any thoughts on the problem?
Secondly, is there a Kubota or other brand of raw water pump available to me so that I don't spend an entire SSI check at the Yanmar dealer?
Thanks in advance.
