Well, there is a 3/4 NPT in the side of the keel. I am assuming it is just to drain the bilge once boat is out of the water.
I have never used an Atomic 4, are there any zincs within the motor I should change this winter?
What should I keep on board for spare parts, i.e. plugs, wires, roter...?
Any other parts I should check this winter?
