    Tacho Problem

    My tacho has been reading high for a while and I may have found the problem. I noticed the signal wire to the tacho, leading from the regulator, was wrapped in a loom that also had the 2 yellow AC wires from the stator in it. The signal wire ran parallel to the stator wires and I think was...

    Thermostat removal?

    Does anyone know wether it is standard practice to remove the thermostat if the motor is run in salt water? I was talking to a mechanic today and he said it was standard practice to remove the thermostat when they knew the motor was used in salt. His reasoning was that the thermostats can salt...

    impeller change

    When you replace an impeller do you need to fit a new seal that goes between the top of the water pump & the water tube to the top of the motor? Had a mechanic say it should always be changed. I hadn?t heard it mentioned before.
