Engine blower timer – Discussion

  1. Just a quick question relative to existing blower motors in the 380.
    Is it recommended to leave the blower motor running all the time while doing any extended motoring to relieve the heat from the engine compartment?
    I am quite sure the blower motor in my boat is the original, but I do find it quite noisy not a bad shaft or bearing noise just plain loud. I have been on other boats and you can barely hear the blower motor running. Has any one had to replace their blower motors yet and if so any recommendations for a unit that is quiet?
    Thanks Paul
