I’m pretty sure it was mostly used in fresh as I didn’t find any real corrosion issues on it. The gearcase and pump bolts came undone quite easily and everything had been greased. It had been taken care of.
I’m sure the grommet is OK and it’s the T-stat which needs attention as it flows water well out of the telltale and it also starts pumping like a garden hose out of the idle relief in 10-15 seconds once everything inside is filled up. All of my other 9.9’s take close to a minute for the stat to warm up and open before any water comes out the idle relief ports. When the owner was here yesterday, it wouldn’t get any warmer than 78 F while running in gear at a fast idle. It’s running too cold.
I gave him a list of the parts needed to remove the powerhead to get at that grommet so if he picks them all up, I’ll do the grommet to while it’s in. It will give him peace of mind knowing all is well.
