OK, I'm putting my boat in the salt water for at least a month while my trailer is fixed. (maybe as long as 3 months)I'm adding a bilge pump to the cabin, with check valve and float switch.(I may add a bilge to the laz, w/ float sw)what else should I do when I keep my boat in the water?do you think its better to keep the motor down or up?what about the balast? add some dry chlorine?any electrolysis issues to worry about (like the balast cap/plug/rod?)I have 2 yr old alabative paint, which I may freshen up... none on the ida rudder.anything else I should or must do?thanks!
