    supercharger salt pitting

    thaught i would post up some photos of my charger, salt corosion is an issue and as my clutch is blown i decided to focus on my salt corosion on my charger, upon removal of the salt i noticed a lot of pitting in my ally casing, left over time this would get worse so i nipped it in the bud now (not that it would get bad enough to hurt the charger but better with none than have it eat away.) im not raising any banter here just showing you guys what i did to remidy the issue i had. my rocker cover also has the same pitting

ID:	1919414th and 5th pic is of the charger with corrosion inhibitor added, this is 30% lead content and is more commonly used in the coating proccess used on nuclear subs to stop corrosion. and is the first prime coat

    Good ideas.......and looks good......next time i have some down time on my ski.....i want to get the valve cover and sc powder-coated.......as the oxidation and pitting of these parts that occurs with this 'naked' aluminum is ridiculous......

    ive only done this as my clutch is blown and yamaha are out of stock (or were when i ordered on monday) as i have down time and the charger is off i thaught i would sort it before it got worse. with working in the shipbuilding and oil industry (nuclear subs and oilrigs) ive seen ally and soft metal fatigue, left over a long period of time the metal takes a good beeting and left untreated can rot ally. it wouldnt have bothered me if the clutch hadnt have gone as i was keeping it all greased up, my rocker cover is next, that is very bad also, 62hrs use

    These things needed a good dose of clearcoat or paint on everything. That would have prevented that mess. That's what saltwater will do to unprotected aluminum.
