We have the WH95TP unit on our boat. It has worked great for 10 years. Last weekend there was water leaking from behind the unit. We turned it off and turned the water flow off and left for the week. When we returned, we turned both the unit and the water back on. The inside of the unit seemed to get really warm and had a slight smell. Then water began leaking from inside the unit. We turned the unit off again. Any idea as to what is causing this problem?

Yes replace the manifolds and make sure that they are empty of water during the winter

If your water filter is located behind the grille at the bottom of the refrigerator the O ring seal is leaking. Happened to me. Get a new one.

RE-SYCHRONIZE CARB(S) AND IGNITION COMPONENTS PER SHOP MANUAL

The lower unit and oil draining is in no way related to the motor.They are two completly separate units.The g/box is totally self-contained.It sounds more like you have an engine problem.You don't say if the motor is carby or efi(fuel injection).If carby,The carby's are playing up.Be it float levels,stuck needle and seat.A prob.But not a big one.If it's an efi motor it needs to be serviced and so does a carby motor.You don,t have a big prob,just a service one.Hope this helps you

the alarm could also be for water in the bilge ( hole in the boat)

Is this a lot of water, or just a small amount.

As the unit sits over time and runs heating cycles, it may have some vapor come out of the vents. That will cool and collect around the unit.

try turning the unit off for the weekends. If you still have water around the unit, then it may have a leak in the tank.

if the prop spins out of the water but not in
it could just be a bad hub inside the prop
good luck with it

Sorry, I just threw out an '88 Subaru manual over the weekend. I have owed the same car before. I think the water-pump is in the front of the engine. Unless absolutely necessary, you don't have to take out the A/C unit. You could take out the radiator/hoses to give more room, then take out the water-pump. Remember: first-out....last-in. !

The machine in let water filter is block clean the filter and check the water flow
