Pivot tube repair
Submitted by Bradmac73 on Fri, 2022-03-18 14:09
G'day all,
The steering on my boat has become increasingly stiff. Thought it was the cable so serviced that only to realise it's some corrosion in the pivot tube that's causing the issue. Can't seem to find a marine mechanic who is interested in fixing this for some reason, so it's gonna be a DIY.
Anyone on here ever attempted this and have any pointers or traps for a novice I should be aware of? From what I can find so far on the trusty google looks like a complete strip down, leg off, power head off and then onto cleaning up the pivot tube.
Appreciate any advice, even if the sage advice is "don't f******g do it"
Motor is a 75hp Merc 2 banger
cheers

Bloody hard
Can only say what i did with my Honda. Are you sure it's corrosion?
The proper repair is powerhead off and full strip but my Honda 50 was old crusty grease and the new grease wasn't getting thru the whole shaft just pumping stright thru the top of the swivel and not working down the whole tube.
Not much help online but removed grease nipples and made adaptor so i could force petrol in under pressure and that washed out the shitty grease. Was a long and time consuming process over 3 weekends - pumping and allowing the petrol to dissolve the crappy grease but eventually the outboard turned well and then spent a good 6 hours pumping grease and ensuring it filled all the voids and got rid of the petrol residue.
Cannot be sure this is your issue as i had no signs of corrosion just very tight.
Good luck!!

Silicone
I just shot lots of yama lube silicone spray down there and it rehydrated the grease and it came better than new.

Same same
75 Johnson ,pivot tube kill rust the shit out of it. I use a rag on a piece of wire to run in and out over a few days .Then tried to seal the ends up so water doesn't get in PVC caps and sika.
But that's only if its not snapped already, if it has ref to

not easy to do but if you know your way around tools, shouldnt have too many problems for diy.

My understanding is that
My understanding is that inly oil should be pumped into any grease nipple on the tube as I brkieve the grease will go hard. Uaing oil I found the steering never gave trouble
