Re: Washing down Powerhead
The marine techs can add to, or correct me if I'm wrong.<br /><br />As with an automobile engine, washing is a common sense operation.<br /><br />My proceedure would be;<br />I'd keep the washings to a minimum. Instead I'd wash it rarely, yet inspect and apply a moisture barrier very regularly. <br />An initial thourough wash down and a good application of a moisture barrier. <br />My owners manuel says spray silicone. As a note here, silicone is poisonous to O2 sensors. So keep it away from your induction.<br />I'd keep the water away from any electronic components and the induction.<br />I'd also perform my wash before you flush the cooling system. <br />I'd leave the cowl off while your flushing and bring the motor to full operating temperature to utilize engine heat to help dry the water. Compressed air would be even better.<br />After the motor was dry I'd spray the barrier.<br />Touch up any linkages with grease.<br /><br />Diligence with the inspection and moisture barrier will serve you better then regular washings. Even fresh clean water causes corrosion, isn't good for electrical components and promotes rot and fungus.
