Default Bobby's Bravo Blues(Worn gimbal ring)

So I got the boat out of winter storage and the marina in their prep pointed out how dangerously loose my steering had become. I noticed looseness when I first got the boat and tightened up the steering arm bolts cause the boat already had the holes with plugs in the transom assembly. It was better but still had some play. Now it had a ton of play ~3" and decided to bite the bullet and fix it.

Didn't take any video of the play unfortunately but here is pictures of what I started with:

Weighed the options of replacing the whole transom assembly vs. fixing the gimbal ring. If I went the whole transom route I could not do the work myself as I did not have a good way to lift the engine plus I could not find any good used transom assemblies within a reasonable distance so I was looking at new around $1800 for the transom assembly before labor.

Do to this I decided to repair they one I had using JR's Marine method. Even though I already had the Mercury style side holes I sed messed with them once and it was horrible. Also the drilled tap holes were not done well and looked like frickin frankenstein! I've wanted to get rid of them so this was my chance.

So I had the pleasure of calling and talking to Ron Bender(awesome guy!) and order his plate kit and rented his special wrenches.

Drive off and on shady homemade stand:


Hole cut for plate... no turning back now!


With the hole and Ron's wrenches undoing this stuff was pretty easy. Did have one issue were a piece broke below where it was suppose to, the plate covers it and should not be an issue but I'll fix it anyway:


Looking a little empty:

So did I mention I hated those ****ing plugs on the side that made my transom look like Frankenstein?

Found some stainless washers that where almost the right sized beveled the washers and holes so they sat flush. Then used some marine JB weld epoxy stick and pressed it in from behind against the washer any that came through got it as flat as I could and make a good seal.





After giving the JB weld stick time to cure I followed it up with normal liquid JB Weld to make sure everything was sealed and give me something to try to sand down flat and make it look cosmetically nice. Also fixed the little piece that I mentioned that broke off that was lower than planned:

So with everything out I examined the gimbal ring, swivel shaft and the steering arm on a table. Seems like the play is in the steering arm. The swivel shaft looks fine and so does the gimbal ring where the pin goes through. The gimbal ring shoe does have wear so the gimbal ring is going to JR Marine for him to fix that and inspect and fix anything else needed on the ring.

Top of the gimbal ring:


Sanded down the liquid JB Weld on the old holes trying to get a smooth surface. Still some high and low spots and don't want to use any ploy body fillers on something that is underwater so much. May just get it as flat as I can and call it good:



Also took the bellhousing and sanded off any corrosion and gave it a fresh rattle can job of Mercury Phantom black:

Thanks, money saved yes but might use that "money saved" as justification to buy some other stuff

Interesting find as everything is torn apart... my bell housing has no hole/provision for the oil feed valve but my transom has a line for the oil feed but that has been cut. I'm just going to plug the line and put it back together as it was cause it works.

Also decided to go with newer style bravo decals just cause I like the way the look better than the 89 era ones:

Want to reiterate how great Ron Bender at JR Marine is! He said other than the damage to the shoe my gimbal ring was ok and only charged me to fix that and put new bushings for the pivot pins with a 2 day turnaround. He could of easily said I need the swivel pin area repaired and cost me another $265 dollars.

So along with my R&R-ed gimbal ring I also got JR Marine's stainless swivel pin and high-strength u-bolt.



Ordered all the other parts I need to put it all back together. Also got all creative with the plate from JR Marine while I waited for the gimbal ring to come back.

Hoping to get it done so I can use the boat for this 4th weekend got my butt in gear today.

Repaired gimbal ring, new steering arm, all new bushings washers etc.., installed. Everything is nice and tight and within tolerances.





Scrapped off the old decal sanded and prepped the upper transom area for paint.

Looks like its coming together well. What is acceptable play and when does it get "dangerous"?
