Perfect thank you so much for clarifying, I definitely want an access hole where I am able to spray some WD40 (been using it for years as preventative for rust accumulation on the jet ski) with a straw container, once or twice a year before winter and after rinsing. While I have it open I'll have to see where the best place is, but your hole is a good place to start, thanks!
