If you really want it, you could go all out and install cooling lines. Mr gadgets plumbed a cooling system on mine 7 years ago. Then the temp sender is inside the boat. That is good for a 40-50 degree difference in drive temps when run thru a cooler inside the boat.

I know NEO oil is $85 a gallon, but it might be a cheaper solution. I can run 70-80mph with a full tank and 4 adults for miles and when I stop I check the drive temp and it's barely warm to the touch. I do have a good drive shower with a billet finned top cap.

I had some made a long while ago. What I found was once the sender went under water from coming off plane -- the temp drop a lot and fast so that told me if water hits the sensor the temp most likely is not accurate.. Also I did buy a few others to test. I tested with a cold water spray bottle at the sensor while running on the water hose ---- the temp dropped hugely very fast. Keep in mind I was only spraying the sensor and right at the vent hole.. Maybe this one had changed but I did have it as well years ago to test -- pic below just before I installed it. Did not pass the spray bottle either at that timeframe.
