Hi folks i need to pick your brain regarding the trim tilt hoses on the cylinders of dp-sm. This is a new to me boat and i noted 1 hose the crimped part is cracked and the other 3 are not looking too good. I am currently rebuilding engine and other things and somewhat on a budget. I looked into getting the hoses but 300 for 4 hoses is overpriced. I would like to get your opinion on getting the hoses rebuilt by a hydraulic hose supplier using the same connection threaded part. I would transfer the ends to new hoses. Of course with stainless crimp. What are your opinions on the matter.

I went down this route a few years back as mine were chaffed where they rubbed against the transom shield. (salt water and barnacles, tube worm etc.) I was unable to find anyone who could or would attempt to make new ones, reusing the end fittings. So I bought new from VP.
Here is the bad bit, I was unable to get the hoses free from the manifold that passes though the transom shield despite having the correct spanner ie. Brake nipple spanner. I had to remove the hose connection inside the engine space and pull the manifold out with all 4 hoses attached. Beware.....
I have wrapped the hoses with the plastic spiral electrical cable tidy that can be replaced when worn rather than the hoses needing replaced.

Whenever possible, I put vise grips over the brake spanner - keeps it closed so it does not slip. Of course some things are too tight for this.

If the hoses are going to be replaced, just cut them off and use a regular box end wrench.

Removing the hoses is not the problem. Having a hydraulic shop rebuild the hoses with new hoses but staying with the old stainless ends.

When I replaced mine I had similar trouble with the manifold. Also, and more problematic, when I did finally get to the manifold, much of the threads of the aluminum manifold came out with the stainless ends of the hose fittings. I cleaned them up best I could with a bottom tap. So far it's holding. That little hunk of aluminum, no moving parts mind you, is shockingly expensive.
