Re: drive unit u-joint rust?
While you have got it apart you might as well replace things like the u-joint and the gimbal bearing. Better than pulling it apart again in a year or two to do the same thing....

Re: drive unit u-joint rust?
Snapped a couple of more pics, looking into the rear of the gimbal housing. doesnt look to good to me, what do ya'll think. I did take her out on the water a few months back and heard no funny noises such as whining, clunking or anything bad like that, not even on the sharp turns or at different speeds

As long as you have a few nuts, bolts and screws left over after the job is done, it should work!

Re: drive unit u-joint rust?
That is a wreck waiting to happen Paul. 
Need to change out that bearing for sure in my opinion.

Change the boot too , you're already half way there.

Re: drive unit u-joint rust?
Yes , it definitely should be clean. A little grime is acceptable , along with a bit of grease from greasing the gimble bearing. Rust/corrosion is second only to water when it comes to bad things happening with anything having to do with bearings. 
You got time , as long as the wallet holds out for a bit longer.

Re: drive unit u-joint rust?
Its always something! Thankfully it is a fairly easy fix! Better to find that stuff now than in the heat of the season.

Re: drive unit u-joint rust?
This is true, motoxxx! Downtime in summertime is disappointing! Think I'll just have my boat shop install a new one. By the time I bought parts and bought the tools to do it, it would cost just a little less than having a mechanic do it that knows what he's doing

Re: drive unit u-joint rust?
That's not a bad idea to have a shop check it out. I wouldn't have tackled that stuff but my old man is a television repairman, he's got this ultimate set of tools!
