If you have had a overheating issue and not being able to get it figured out I can almost guarantee this is your problem. If your engine runs fine on the hose at home and runs fine at low speeds on the water but starts to run warm at mid to high speeds or after running a fresh water cooled engine for a half hour or so you need to replace the water supply hose from your drive to and through your gimbal housing. Over a period of time the gimbal housing starts to corrode right at the point that the supply hose goes through the housing and as the corrosion expands it crushes the plastic insert that holds the hose in the housing and closes off the water supply, sometimes over 50%. No matter if you use your boat in fresh or salt water this can happen. You really can't see it unless you take it apart. MerCruiser makes a new designed hose that keeps this from happening. I have told many boaters about this issue and most just don't believe me and they continue to go about changing their impellers, pumps and flushing their cooling systems with no luck, it will keep overheating until you change this hose out, see pictures, look close and you can see the blockage. PM me if you have any questions.
