What kind of hose for a cockpit drain

[manuga]

I'm replacing the cockpit drain hoses and sink hose. Any suggestion about what to get?
Hoses cross under the cockpit and connect to thru hull under water line.

My cockpit drain exits the transom of my boat slightly to the side of where it goes through the floor. I took the old plastic hose off and went to the auto parts store and found a radiator hose with a perfect shape for what I needed. I used the old hose to get close. It looks great and should last as long as I need it to.

What size do you need? Do you current drains ever clog?

Our boat had piddly little cockpit and bench drains that would clog with 2 small leaves and a twiglet. Or one wet pussywillow. I upsized to about an inch and a quarter hose, which means the fitting openings are just under an inch. I used sanitary hose because it's slippery inside, is fairly rigid and maintains it's circular cross-section even through bends.

These days your insurance company wants you to use approved hose on anything below the waterline

Like a TRC-10003441B SEAFLEX 3/4"X 12.5'

I still need to pick up a few more hose clamps

Size seems right, about one and half inch. It doesn't really clog unless I park under a tree in the fall.
