Re: 03 Meruiser 350 MPI still running hot

I agree with the air, nothing else makes sense. I ordered a lower seat kit to replace the oring between the upper and lower. Only other thing i can think of is the drive was cut to high in the boat and it is sucking air in the top holes of the water intake. I guess if the seal doesn't fix it, i will put some small bolts with rubber washers in the top 2 holes and try that. I really don't know what else to do.

I ran your serial number on MercNet and you have a couple of recalls outstanding.
One is Service Bulletin 03-01 water inlet hose.
Something is hosed up on my home computer so I can't see what the service bulletin is about but it might be worth looking into.
