Re: Engine Overheat alarm (mountbkr)
Ok here is the deal, I had the same problem, 2007 225 HO on a Z21 with a 10" hyd plate. I recently had the updates done that changes the overheat alarm to a lower temp. Apparently I had been running my motor too high before and the extra heat did a little scorching to the water pump impeller. I was only 10-12 lbs of water pressure at speed. Definately not enough for this motor. I put in a new water pump and now I can achieve 15-18 consistently and sometime up to 20 if I tweak on the plate. If you are like I was you have probably run you motor too high since under the old temp settings the alarm would not go off. You might try a new impeller.
