Dont need the whole kit just the hose. Listed as GLM-47160 but I cant seem to find that or equivalent listed anywhere for sale. I tried pushing it in and the hard tube dented in, I dont trust it to not develop a crack

Aftermarket Marine. You can also get it on Amazon, same price. Claim it will permanently cure the problem.

diameter is small from them -- internally on the end. reduced water flow.

Salt water usage is mainly the issue that causes the restriction. If you are in fresh water that is not needed anyways.

so whats wrong with number 15 ?

Most likely better off with 32-8M0090859 - Hose Kit This kit has everything you need, including the installation tool that you will need. List $ 60 and it is still available.

That one is more expensive than the whole kit I posted, looks like it is smaller diameter as well and still restrictive

Thats what I bought, but pushing the one in it dented somehow, even lubing the **** out of it. i need just the hose
