I have been replacing all the hose on our Endeavour
40 the last year. Getting to the deck
drains is a hassle. There are 2 of them, port and starboard. They are located behind cabinetry, and it is not easy to get to them.
Be sure to use caution when removing hose from old thru hull
fittings. I broke off the propane
locker thru hull
fitting trying to get the hose on... but it needed replacing anyway. After 25 years they get brittle.
There is a lot of hose in one of these boats. It adds up to a small forturne.
Use new clamps as well. The awab from defender Hose Clamp
are the best, but expensive. mcmaster carr has clamps that cost less, just make sure you get the ones with all stainless, including the screw.
The best head
hose is the Trident sani shield hose. Trident Marine: Sanitation Hose
It is heavy and will last a long time. The sea land is a distant second.
the hose up first works well, but not always. I spent 2 hours yesterday trying to get 1.5" water fill hose to go on a 90 deg elbow
and still not satisfied with it.
You might as well rebed your deck
fittings while your at it.
Don't forget to double clamp the below the water line connections.
