BF100A - External corrosion on Bottom spark plug

[Kiddsinoz]

Hi All

I have a 5 year old BF100A that sufferers from corrosion on the outside of the bottom spark plug. Last time it had a service the dealer had difficulty in removing the bottom spark plug due to this corrosion. It appears this is a result of a small amount of salt water entering the sparkplug access hole despite the rubber boot on the coil pack. The dealer suggested that the water was coming up the leg cowling if I stopped quickly or reversing into a bit of sea.

Just wondering if anybody else has experienced this issue and if there is a solution

Thanks in advance

Ian

Start by putting a small cable tie on the water tell take pipe, they can leak or worse, pop off flooding the engine. Other than that, clean it up, put antisieze on the plug threads and spray the area liberally with corrosion guard.
