Overheating starboard side of engine

[spareparts]

put a water pressure gauge on it and report back. When you replaced the water pump, what brand did you use? Did your replace just the impeller or did you replace the housing as well

I used the Mercury OEM pump kit replacement included Impeller, gaskets, upper housing, small plastic water tube etc. For the pressure gage, does this get attached at the hole at the top of the engine that has a threaded plug in it?

Thanks

I think I may have found my issue with the water flow on this engine. I was running at 3K rpm and inspecting the engine for any source of water leakage where it shouldn't be. I found water spurting out at the exhaust plate connection - where the power head meets the exhaust tower. It looks like a piece of the gasket is compromised. The higher the rpm, the more water spurts out this spot. Does this sound like the culprit? How hard is to to replace this gasket? I'm assuming the power head has to be lifted?? Annything else I should replace if I separate the powerhead?

Thanks

I think you just found it, the exhaust pressure will get into the cooling passages and prevent water from entering(exhaust pressure greater than water pressure), you will have to pull the power head. The power head bolts(studs) can be a pain
