Loose Jet Pump

[Thermobrett]

Can somebody share some photos of their jet pump? Pulling the kids in the tube, somehow my rudder turned and lodged sideways under my @Cobra Jet Steering LLC steering fins. I was able to get the boat back to the ramp and lift the pump and swing the rudder back into place, but I don’t know if I am missing something that caused the pump to lift. Any advice is greatly appreciated!!

How is that even possible? Its connected to both jet pump nozzles with the cf’s.

When I get home I will post some pics.

I'll be able to get more or different shots a little later if needed, I'll post a few more complete shots if I can track down any

This is what I found after taking the boat out and back on the trailer. I originally noticed the issue when the steering became very heavy and had no left turn. Looks like the top bolt is loose allowing the pump head the rock up and down.

Edit. Further inspection the bottom bolt and bushing is what fell out of the pump. The is the top one to verify it didn’t shear off and fits.

The only time That happens is if someone removed the bolts and did not use thread lock on them And the steering you have does not require the nozzle bolts to be removed for the installation and the top one looked loose also , Did you have any work done on the nozzle or pump recently?

That top bolt looks like it has thread locker on it (the red stuff in the threads), so what @Cobra Jet Steering LLC is saying would make sense. No thread locker, in addition to gravity and vibration working to loosen the lower bolt.

Some folks might assume since there's still "Red" on the threads, it's good to go right back in, as if Loctite works like a nylock nut, or perhaps they didn't clean the threads and reapply?

Regardless, sucks that it shortened your day. Does there appear to be any collateral damage, or will you be back in business with some new parts and fresh Loctite?

No pump work done, guessing this may have just been from the Covid manufacturing process at Yamaha back in late 2021.

A quick stop at Ace Hardware for some new stainless steel bushings, bolts and thread lock and we are back ready to do it again. $11.59 to do it myself, or $111.59 for the dealer I’m sure.

If it was me I’d run a tap into the threads and a die over the bolts and blow out the bolt holes with compressed air to remove any original loc tite and moisture before re assembly.

I’m going to add this to my preventative maintenance plan to trust but verify they are good. Great idea, hitting the tool room tomorrow for a set of tap and dies.

Be sure you get the factory standoff for the bottom hole part number is 90387-08m30-00 it is the same as the top one and it creates a void for the nozzle to pivot freely

Thanks for the info!

Whatever you do, don't buy harbor freight tap and dies. they are a complete garbage. as are most of the ones in the auto parts stores. Northern tool sells a brand called Klutch, they are pretty decent. If you buy the cheapest ones you can find you will be throwing your money down the toilet.

Milwaukee has some sets in Packout containers slated to drop in August that I am eyeballing, doesn't help right now (unless my timeframe is off) but for future readers.... Price looks reasonable as well, but that could easily change

make sure you put it back together correctly, a nozzle can be expensive,
