Have Boat Questions? Ask a Boat Repair Expert.
Hello my name is ***** ***** am I speaking with? I read what you wrote. Is the engine actually overheating, did you verify the temperatures by checking the engine with an IR temp gun, or are you relying on the gauge in the boat? Can I also get the serial number on the engine please.
Okay got it. How are you running the engine, are you running it on a garden hose or is the boat in the water?
Got it. Are you near the boat now for a test?
Just a screwdriver and a bucket. All I want you to do is pull the output hose off the seawater pump. Start the engine up. Bring the RPMS up to 1000. Once the water starts flowing aim that hose into the bucket. Count to exactly 10. Then aim the hose away and shut the engine off. Do this and let me know if you get more than a gallon of water in the bucked or less than a gallon of water.
Okay let me know what you find.
Hi Paul. Okay that is to low, you should have had 2 gallons minimum. When was the last time that impeller was replaced with a new one?
The impeller was new 1 month ago?
Right now there is not enough water out of the pump, it should be double what you are getting. You will want to check the water inlet on the boat and make sure that is not clogged. If there is a power steering cooler on the seawater pump inlet hose that will need to be checked for clogs. When the engine runs, the seawater pump makes a vacuum and sucks water up from the lake. What can also happen when the hoses get old is the hoses can simply collapse under that vacuum, so that will need to be checked as well. If that all looks good then there is a problem with the impeller or the pump itself is no good and has excessive wear inside of it. Does that all make sense. Also, this engine does call for a 140 degree thermostat, so you will want to use that one. I do want to make sure you are happy with my service before you go.

Thanks in advance, and good luckJason
On most of them there isn't any kind of strainer/filter, but you would have to take a look as every boat builder is different.
That would do it. When the engine runs the water plumbing is under a vacuum. What happens is the seawater pump will suck air in through that leak instead of sucking water up from the lake. Does that make sense.
It looks you read my answer and left without selecting a rating for my service, replying back, or simply thanking me. Was there something else?
