I started the project of replacing the bilge pumps today. They were cracked and in need of replacement. While doing this I also painted the bilge area where the pumps were located. See the before and after pics below.

In the after pic take a look at the bilge pump hoses in the background. Those are original hoses that were installed. They are not easily flexible and I ended up breaking one of them.

I'm hoping I can find a corrugated hose end attachment, something similar to the original hose end in the above pic. If not I have to replace the entire hose and that is a bigger job than what I want to sign up for right now. Has anyone had to replace the corrugated hose end before? Where can I get the part?

I can't "get it" from the picture. Are those just bilge pump hoses like the usual ones attached to the bilge pump to suck out water that gets in? (I can't see where they would pick up water). If they are just hoses to carry water over board when it gathers in the bilge, they don't have to be any special type, and in fact the corrugated aren't so good because they hold so much water in the corrugations. Just get any hose at an auto parts place maybe..
 
If those are the seacocks for the cats ,how come they look different in size? Plus your bilge pump is inadequate for that size vessel(at least a 2000 or a 3000 gph in the engine room alone.)
 
From the looks of it you might want to replace your rubber hoses attached to your seacocks. The one on the right looks like it about to fail unless its just the angle of the picture.

Paladin,

Yes. Those are regular hoses for the bilge pumps. A 2000 GPH pump attaches to each. What you can't see is that the hoses route up behind the water tank and to the rear of each side of the boat to discharge outlets, which are in extremely remote and practically inaccessible. My objective here is to leverage the existing hose if at all possible.

BT, I have three 2000 GPH pumps n the ER. The seacocks a are not the mains, which are properly sized. What you see on the left is the genny, and the right is holding tank discharge (never used).

Duly noted Camella. The left seacock is the genny and I will be replacing the hose at the end of the season. The holding tank discharge on the right has a lower project priority since it is not used. All other hoses for the mains are new.

Might be a good idea to close the seacock for the waste disposal in case the hose fails or the Coasties happen to look down there.

My concern with trying to reuse the bilge hoses would be that they have obviously degraded. While it may be a PITA, running new hose will give you peace of mind for such a critical element in a boat.

The inside of the bilge hose should be smooth, right?

Just find a connector that will work for the inner diameter of the hose you have. If you plan on replacing the hose entirely in the off season, then just got a chunk off and re-use that cuff as needed.
 
The corrugated tubing that Sea Ray uses is thin and brittle.

I think pond tubing would be a far superior replacement compared to what the dealer or home depot will have. Its made to withstand crushing and harsh elements. You will never ends to replace it again.

You should have a check valve somewhere upstream. That would be a shorter hose to replace then all the way to the thru hull fitting. I know what you mean about the cuffs, I had no luck sourcing them when replacing bilge pumps on my last boat.

The fact that it already broke off would make me replace the entire hose. That stuff's cheap and brittle. I replaced the OEM with smooth wall bilge tubing, and used the same when I added a second pump for redundancy.
 
Update: I was able to reuse the hose end by heating it with a heat gun to make each part pliable. I used a pair of needle nose pliers to twist/tear the hose section out of the end - came out pretty easily. I reused the hose end and screwed it onto the existing hose I was able to save, and used 4200 to seal it. Works perfectly.
