Boating is expensive enough without having to have security to protect your stuff.
Even with all the time that I send on mine I miss things.
While running last season I noticed a little water in the bilge, not a lot, maybe a half a cup, never got any worse.
Last winter I put in my new remote oil filter, so this past wk-end, I lit her up and while I was checking to see if the new system had any leaks (none), cool.
While doing this I noticed a small drip-drip-drip of water coming out of my power steering cooler, that I had worked on 2 seasons ago.
Evidently I didn't get it tight enough, it wasn't going anywhere, just needed a half turn with the wrench. Mystery solved.
As I get older, when I think I got it, I look again.
