Paid marina to install new impellers 2 years ago (about 50 hours been put on). 1999 Mercruiser 7.4L Horizons closed cooling. Yesterday got white smoke on port engine and saw a sheen in the water outside exhaust port. And temp. was higher than starboard engine. Started engine today and no water flow. Shut engine off.
Can anyone think of a way to not get flow outsiders of bad water pump impeller? Strainer is clean. Plugged heat exchanger? Can I check if by taking off tbe round end cap?
I supposed tbe marina porked me and never put new impellers on. Otherwise I'd say most likely impeller shot. And not sure about the sheen in the water. Coolant is full. Oil good.
Any thoughts?
Thanks
