Is this normal?

No seacock on the manual bilge pump thru-hull.
Hose that looks like one I use to vacuum my pool.

Bilge discharges should be above waterline at any angle of heel so seacock not needed or wanted, a closed seacock could cause a delay. Manual pump is usually used in "panic mode" electric auto pump failed and "oh my god there's water on the floorboards".

Not normal by any means. That throughhull needs a seacock and the hose should be replaced. Not cheap but it is an easy fix.

Calif.Ted has it right. A seacock on a bilge pump outlet is asking for problems.

It’s hard to tell from your picture where the bilge outlet is on your boat, but as stated before , it should be above the waterline for any normal sailing angle.

It should loop up as high as you can get it under the deck before hitting the outlet mushroom, to prevent siphoning if the outlet did take a dip.

If it’s below the waterline, you need a sea clock, and I would replace the line with heavy duty water hose, at least to the high point of your loop.

I have seen outlets and pipe like that above the waterline. I really hope yours is above the waterline. (It might be normal but that doesn’t make it good) if that weak looking thru-hull were broken by a heavy object, could the boat take on water? If heeled?
I agree with Matt, add an anti siphon loop.

That hose has got to go !!! I can tell you a horror story about that type of hose that led to a near sinking. That accordion type hose has no room on a boat in my humble opinion !!!

That hose is not even clamped, nor could it be. It is simply held into the cuff by friction. The cuff is the only thing that is clamped. Scary.

The cuff can be glued on with 5200 or similar adhesive caulk. There is no way to tell from the picture if it is glued.

While I am not a fan of this type of hose I still two lengths of it in my boat. It has not been a problem.

It is totally normal to have above the heeled waterline discharges without seacocks. I do agree that the hose should be looped as high as it will go under the deck to prevent backflow on rare occasions where the discharge may be underwater. There is absolutely no need for a vented loop on this application.

Those cuffs are vinyl. Vinyl is not listed on the 5200 spec sheet as a recommended substrate. Hope yours are well above the waterline at any angle of heel.

Mine are well above the waterline. Vinyl may not be on the substrate list but they are stuck on pretty good. Considering that these are discharge hoses there is no significant pressure on the cuff.

As I said in my prior post I am not a fan of this type hose but it does work.

Don,

The loop is more to prevent a siphon starting if the outlet dips under, than an actual siphon break - if the hose gets fully filled, it will still siphone, loop or not.

Had that happen on my last boat - an allied sea wind 32, had the bilge mushroom out the flat transom about 6” above the waterline at rest.

I discovered that underway under power, the stern squatted down enough to keep that mushroom below water. When the bilge went off, it would empty, then after the switch closed back down, water would siphon right back in again

Stuck on pretty good - against the advice of the mfg. ok !
no significant pressure - until they are under water like this persistent leaker ? Guess he forgot the non approved 5200. I pulled this one out by light hand pressure while the boat was in the slings ... it wasn't relaunched for a few days

The other problem with corrugated hose is that it introduces friction which lowers the volume of water that can speedily be pumped out

Agreed and more dramatically than most would think if used for bilge pumping
