So, thanks to the help on here I was able to find my overheat issue. It was Bravoitis. Ordered the Mercury kit and just got through doing it. Now here's my next issue, I believe. Where the hose comes int the bottom on the transom plate, well, that hole was pretty corroded and I removed a lot of loose corrosion. Anyways, I got the kit and took @alldodge advice on the Dawn soap so it would slide in easy. All went well and easy in my opinion. Problem is the after I installed the actual elbow that connects to the pump hose and everything was nice and tight, I went to the outside of the transom and pushed and pulled on the new hose. Well, I have movement. It takes some force but I can pull it back and it stops, I can then push it back in. This was also happening with the installation bracket that come with the kit, but I didn't give it much thought and figured it would all get tight when the actual elbow was in. Now, when trying to pull it out, since the plastic pipe comes with a hump that sticks out, I think that, that hump it what's keeping it form completely coming out since there wasn't much corruption damage towards the back of the hole. Most of the damage was in the inside foward portion of the hole. I am also thinking the Dawn soap doesn't help and makes it easy for it to slide. Should I be worried that the hose move in and out like that? I dont know if there is a lot of pressure on that hose when moving foward at 30-40 mph that would cause it to pop out.

Read your statement 3 times and still have some issues understanding where your getting the play, I didn't have any

The entire hose that goes into the transom bracket. The hose is connected to the plastic piece so basically the plastic piece that's in the transom assembly moves in and out.

Ok thanks
That should not happen. The fitting and hose are glued/bonded together. Return for another part, that one is detective

I am not talking about where the rubber and the plastic attach. I am talking about the plastic piece that goes into the transom assembly that has the rubber insert that goes over it. the one you have to put soap on to be able to slide it into the hole.

ok, that is a compression fitting, so the rubber when compressed will hold the plastic pipe

The drive has water pressure against it but not that high. So long as the pipe is inside the fitting, and the rubber disc is compressed as listed in documentation, it will hold

Yup, that's the one I am talking about. My corrosion was pretty bad compared to the ones I have seen, so the opening for the pipe is wider than OEM.

This is a judgement call. You can see and feel what we cannot, and if way easy, it may not work.

Bottom of the transom??? Mine was near top. Provide photos.

Are you talking about where the hose enters the transom plate? If so, yes the hose is at the top of the transom plate. I am not comfortable with the movement I have. I will be removing the hose and building it up with Belzona Super Metal. This way, when re-installing the pipe and rubber grommet, there will be less of an opening and it will be a tighter fit. I will also be adding Mercury Bellow adhesive to the pipe and grommet. If this fails, I guess I will have to do a thru hull pick up. I will take picture tomorrow when I take it back apart and pictures of the repair.

On a side note. I did some research on the gimbal bearing. Turns out the Sierra bearing is the exact bearing Mercury sells for half the price. SKF
