Current situation:
1. Have owned boat many years and never had issue with losing prime
2. i am able to prime by sticking garden hose in strainer and holding rag over top to create water pressure and have someone start generator.
3. Once started, generator runs fine. Pumps plenty of water and does not get hot.
Troubleshooting effort:
1. Noticed hose that goses from sea strainer to raw water pump had a bend in it approx 9 inches from sea strainer. Cut hose past bend and rerouted so it would reached sea strainer.
2. Primed with garden hose and ran generator and looked for a leak, but no leak found.
3. Shut off generator and looked for a water leak, no leak found.
Thought process:
1. Air is getting in at a high point, water goes down to strainer level and prime is lost.
2. Inside of hose is collapsing (not visible on outside of hose) causing the problem.
Next step: purchase new hose and install as the first step in process of elimination.
I don't think this is an impeller problem but if new hose does not resolve issue, then I would check impeller and then water pump. Trying to not go too far into forest on this one.
