I have also found out the best way to keep certain problems from hiding until your in the water is run the boat like your in the water.
I dont use muffs anymore because if you have a weak or totally failed water pump, you wont know about it until your overheating at the lake. Muffs force water into the system as to when your sittng in the water the water pump in the outdrive pumps it into the system. Bad waterpump in the outdrive means very little water gets pumped to the motor, then your having alkinds of issues.
I went to the local hardware store and got a 33 Gallon trash can and used a razor knife to trim it to size. I lower my outdrive into the can, and turn on the hose full blast. this keeps fresh water going into the can and lets the system run as if it were in the lake.
Just my $.02. Do I get any change back??
