F14A water jet

I blew a cooling hose (starboard thermostat to manifold) on one of my big blocks. I have attached a picture with the # 32 89730. The internet tells me this has been updated to 89731 BUT when I look at the picture, the hose seems to be significantly longer and has too many bends.
Can anyone direct me to a direct replacement hose?
Thank you,
Tom

Hmmm looks like the straight end might have been cut. Can you post another photo or 2 with a tape measure in the picture and maybe with the straight end in front. I can pull a 897301 off the shelf and compare.

One issue seems to be that the manifold pipe where the hose attaches does not have a "ridge" to help hold the hose in place...I'm gonna double hose clamp.

Wow the new 897301 looks completely different!

Can you tell if your hose has been cut? Post a close up photo of the end. Also a photo of the engine showing where it attaches at both ends.

It looks like the hose has been cut down to mate up with the GIL exhaust manifolds. It also looks like the T going into the manifold has a "smooth" contour (does not have a ridge/lip for the hose to grab). See attached (not mine but very close). I am sure the boat has been run like this for a number of years (200+ hours) so I think it just vibrated loose and I will double the hose clamps for safety.
Thanks again,
Tom

O - now I see. It wouldn't hurt to pull the fitting and have someone machine a section to give you a lip. We do that all the time when we make fittings.
