Yamaha jet drive plug won't go back in

[Lsutmorg]

I pulled the plugs out using the floor jack trick. Was able to buy bottom half and keep top half of old plugs. Boat was always in salt water and never had plugs removed. A lot of corrosion in plug port. Have cleaned with many different solutions. Port looks clean but plug does not seem to go in far enough for dogs to catch the groove to make it secure. If I force in I have problem with plug becoming stuck. Any suggestions? Can you buy new port plugs go in? Both plugs and 2006 AR230. Thanks

Greese the rubber skirts with Teflon grease. Dow makes a great product in a squeeze tube for rubber o rings.

Are you using a lube........my dealer coated the inside of the boat tube with white lithium grease and also sprayed the plugs with a heavy coat as well. 4 months in salt water, all is well. Most use Yamaha lube silicon spray. If I'm remembering correctly the top half of the plug has a rubber seal it might have swelled making it hard to drop in and locking up if its forced.

So you are saying you rebuilt the plugs with the Yamaha rebuild kit for the lower section? And they still stick? If that is the case, then you need to clean the edges and grooves out on the lip where the plugs sit. You probably have a ton of salt/mineral build up there. Spray heavily with salt away, and use a wire brush. Take some photos of that edge and post.

I will take pictures. I have been spraying with salt away but have not used wire brush. I put WD-40 silicone spray on the gasket but will try something different. Yes it is the Yamaha kit for bottom half I replaced with. So new gaskets and plastic bottom.

agree, you need to clean those edges up. Wire brush, some 600 grit wet/dry. That is what is holding things up.

check this thread out, we had two members within a year swear their rebuilt plugs wouldn't go in, both times it turned out to be the rubber gasket,

also, update your location on your profile, there may be another member close by that would be willing to take a look at it,

And in those instances it was self admitted by one that they over torqued the plug on rebuild forcing the rubber ring out:

I will look at that when I get home. How would I know if I over torqued?

The rubber ring should not be bulging out.

Wow you have a lot of corrosion and some delamination of the plug wall. Your plug locking arms also show some pitting as well. Both are going to require some work for sure. Plug replacement looks to be the easy part...... the tube corrosion and splits in the walls of the tube look to be a serious pain

wire wheel on drimmel tool is my next step. Any other suggestions?

The corrosion down in the tube is easy. Get a drill extension. They are usually 12 or 16” or so. Put that in a cordless drill with a wire wheel in the end. That will look line new in a few seconds. For the plugs i would just order new ones. A rebuild at a min then sand the plastic smooth around the outside edge

I did rebuild the plugs. I have them in working order. Will clean up the dogs and hopefully everything will work. Appreciate the help

you definitely need to sand those tubes clean

Got plugs to go back in with drimmel. Going to use wire wheel when long extension comes in to finish cleaning port. Thanks for help
