replacing water intake hose and found this:

[Jtom7]

I was about to replace the water intake hose for my 1995 Mercruiser 5.7 carb model and when I pulled the old hose I found the nipple/plastic tube had been partially crushed. see pic.. temp has always been fine since I've owned it but my question is should I delay boating and order the replacement and if so does anyone know what its called and how easy it is to replace? Looks like 2 bolts but having never done it thought it best to ask first. Thanks!

If it is running fine its ok to run just watch temp.
part doesn’t look hard to replace from photo

i think its called a water tube or water neck should be in gimbal housing parts digrams

overtightening the hose clamp tends to do that

I'll be sure to tell the person I bought the boat from he or the previous to him tightened it too much. I obviously realized that someone overtightened it the questions posed was part name? and could it be reused this way? not did you think it was overtightened LOL, thats pretty clear already

You might be able to gently insert a tapered tool or wood dowel stick to carefully re shape it.
To replace the plastic tube you will need to pull the drive and bell housing also would be a good time to replace the bellows and water hose.

You think I'd have to pull the drive just to take that tube out? I thought it looked like 2 bolts and possibly a seal that makes the tube water tight to the hose that comes from the drive. I'm not sure how long that tube is though. Not really looking to pull the drive and do bellows right now. Perhaps in fall when I use it less. Think I'll try to open the bent section a bit and plan on a more extensive repair later. Pull the drive is much more involved than I hoped for

I think Kenny is thinking it’s on the outside of the transom , this is inside the boat

If you raise the drive and push the drive over to the port side you will see how the hose is connected to the out side of the plastic tube with a hose clamp. The tube is sealed in the transom plate with a grommet under the flange with the 2 bolts.

he gave me the idea of inserting a tapered tool to reshape it. I decided to use a hair dryer to lightly soften the plastic first then I used a big wire nut I had that fit well and reformed it. Surprisingly it worked quite well and took little heat from the hair dryer. I will be sure to tighten the band clamp further down to avoid damaging it again. Perhaps replace it in the future. Thanks for input gents and Thanks Kenny for planting the idea. The tube does look longer online so it may very well go out the the lower unit gimbal housing and clamp to the hose.

Just be careful to check that clamp at the start of each season. I had that hose pop off on my Cobra and it overheated the engine and filled the bilge with sea water. Not a fun day and the engine ran fine 2 more seasons and blew the Head gaskets at the end of ‘16. Did a top end overhaul in ‘17, still running ok. But, I do get back there each season and check the hoses & clamps. It was that day that I swore I’d only have outboards after this one. Can’t happen with an OB. Safer, less work and better performance overall.

and MO money!

Yep but worth it in the grand scheme of things

Here is a picture of the outside. It is a one piece hose going through the transom. So to replace it you need to remove the gimmal housing and on my boat you will also need to remove the engine to get there.

You can get at that without removing the gimble most times. You may have to remove the steering ram and such to get at it. Unless the motor is stuffed in a really tight spot.
