Corrosion problems

Post by Cat Tales »

Having pulled our engines for some repairs & normal maintenance, there is extensive salt buildup & corrosion internal to many upper unit parts, including the starter & power head. The mechanics all questioned if the engines had actually been submerged at some time. The culprit may be the splashing between the hulls, then entering through the air intake. (That area is a very wet environment and has taken its toll on the cables & connections.) Has anyone else had a corrosion problem or extensive ingress of splashing in the lower nacelle area? For a solution, I am considering a custom rubber boot, or something similar, to prevent splashing. Any thoughts?

Hi Chris & Kelly,

Suggest you look at the cover seal first. The seals tend to shrink over time, especially at the front corners. Splashing seawater then enters and corrodes evrything. Another area to check carefully is the square rubber seal where the shift and throttle cables enter the engine. This has to be very carefully installed and positioned. If not, copious amounts of seawater will enter under the cover.

Hope this helps,
Chet
