I have a Universal M-40 engine is misbehaving. No water flow going out of the exhaust. These are the steps I've already taken:
Questions:
Thank you in advance,
Rodrigo
- I replaced the impeller, although the old one was in pretty good shape.
- I opened the sea cock strainer while slowly opening the sea cock to see if there was sea water flowing in. It does, although is more a trickle, not exactly gushing out. Should water rush out immediately upon opening the sea cock?
- I cleaned the heat exchanger by opening both side caps and clearing any debris there. I have not removed the HX yet, just opened both side caps.
- I have disconnected hoses up to the HX and water flows, again a steady stream, but certainly not gushing out while leaving the sea cock open (and the engine off).
Questions:
- Should water flow with pressure when opening the sea cock and leaving the engine off?
- I was told perhaps the thermostat is at fault. For the life of me, I cannot find it on my engine. Could you point me in the right direction to find it?
- What would be the best way to try to clean the through hull while the boat is on the water?
- I would expect the boat to have a muffler, but unless I have no idea what I'm looking for, I cannot find it. Is a muffler a must on all boats?
- Oil is overdue for a change. Could replacing the oil help in solving this issue?
Thank you in advance,
Rodrigo
