OK, this may be a stupid question but I trailer my boat ('98 Nautique SS) in the lot of my cabin during the week while I am not there and was wondering if I should leave the drain plug in (after draining it of course) or should I leave it out?
I always left it in on my old boat but I never really thought about it until I heard some other boat owners saying they always stored their boats with it out. I just don't want a bunch of earwigs getting into my engine compartment. Thanks!
The only time in 2 years that I have removed my plug is when I was performing service in the driveway and got extra water in the boat when changing the impeller and draining for winter, I never remove the plug after being in the lake. If I pulled it I would put it back in when drained so that I wouldn't forget before next trip.
Take it from someone who is now in the process of replacing a steering cable. Residual water left in the bilge is the #1 cause for premature cable failure. Also the condensation on your alternator, starter, etc.. The dryer you can keep it the better
If it rains a lot where you live and you park the boat outside then leave the plug out. I have known several people that have "swamped" their boat on the trailer because rain water filled the bilge high enough to cause damage.
