The owner will soon be able to make a few trip's around Alcatraz soon,,,hehe! Great to be having your back in 2024 early, Bear.

[@TheAyrCaveShop]

Happy New Year Bear, Yeah it was a busy holiday

[@AdamAnthonyAdventures]

Thanks this was very useful to me. I just did the ujoints. I was able to remove them without separating from the gearbox. The last knuckle is a little tight but a little tierod press did the trick.

[@TheAyrCaveShop]

Glad it helped 👍
Thanks !

[@GardenTractorBoy]

It was very interesting to watch, thanks. Great tip about using some scrap to stop the ears of the U/J bending

[@TheAyrCaveShop]

Thanks Joseph, Yeah there a bit tricky

[@westmichiganfishing9613]

You are the best, I'll be removing my lower unit in the spring to replace the steering helmet bushings and V-gasket. During this time, I plan on inspecting the u-joints, replace the bellows and any other PM I see.

[@TheAyrCaveShop]

Thanks for the nice comment... So important to keep up with the maintenance 👍

Spot on!👊🏻🇺🇸

[@westmichiganfishing9613]

"Fineness it, don't force it" wise words. You should put that on a shirt.

[@TheAyrCaveShop]

A couple of my buddies need that shirt 😎😎

Thanks Matty !

Great video, but how did you remove the 4 bolts that hold the housing? Mine won't budge!

[@TheAyrCaveShop]

Yeah they get very corroded. Be carful it's common to break them off. Here's some tips:
Use a propane torch and heat up the side of the housing following the bolt path, concentrate on the bottom 2/3 of the bolt length. When the paint starts turning a brownish burnt color that's about the right temperature. With a cutoff length of hex key use it like a punch in the bolt head and give it several sharp hammer blows. This will help break the corrosion bond, then Then try loosing it. You may need to work it back and forth and add penetrant. Keep repeating the process as needed.
I've had to scrap several units that lived most of there life's in saltwater do to the frozen bolts.
If they snap off at the threads they can be drilled out and saved. The ones that snap off just below the bolt head are almost impossible to save.
It's the bolt shank that's the issue in most cases.

[@ssm5372]

Thanks for the detailed advice! If they won't come out I may snap them off or drill the heads out, take it apart, heat up the remaining shanks and get them out that way. I may have to weld nuts onto the shanks to remove them. If that works, I may try putting in studs and have nuts and washers to tighten everything down. I don't know why they didn't use studs and nuts to begin with so the corroded threads would be right in front of you instead of hiding the problem 1/3 of the way into the unit body. My problem is I have to replace the input shaft seal so before I do all that I may try AT205 in the oil for a season to see If it will rejuvenate the seal. I'll just have to check the oil level a lot! 😵‍💫

[@BaldGuyComedy]

Do you have any info on Power trim models like the 270pt or 280pt ? They seem super rare which makes me finding ANY repair info next to impossible.

[@TheAyrCaveShop]

Absolutely right there are rare.. I've never worked on one or seen one in the wild.

[@dzmarinemechanics3238]

Hi, this upper unit that you're working on always overheats when i start the engine, in the first 20 sec os start, when i pull out the dipstick the oil is very hot and get out from the dipstick hole, what could be the problem ??

[@TheAyrCaveShop]

That could be a bad bearing

[@danmacko8795]

Possible to have you rebuild my 290sp
