I have a 91 wellcraft V-20 with 5.01 chevy. I want to change out the drive shaft bearing (shaft from engine to outdrive). What does it take to pull the engine. Don't I have to pull to change this bearing?

Also I want to put new bushings in the steering fork, can they be changed by taking out the top part of the outdrive? Any special info I should know? I just installed new heads because I found water in my back 2 cylinders on each side, I did find rust around the head gasket bolt holes on the ones that bolt into the water passages, I'm hoping that was the cause but I did have cracks in and behind my seats in the heads. Anyone have any info or comments on these issues? I've had it running since head job and it seems to run ok but I have only run it on the the trailer dunked at the boat ramp.

Hope you wiil be fine with the motor!! I have been there done that!!
I had the 6 (chevy 250) and the head rotted a hole in it and water was every where! I was able to save the motor!
But after that I found there was a lot of rot going on and it spread like crazy!! I ended up changing riser, manafold, oil pan Ect Ect Ect...... Only for another rot hole to allow water in the motor? Thats when I had to repower!
But mine was raw water coled and the salt going thur that motor wasn't good!!

Any way if you working on the shaft going to the outdrive you are going the wrong way!!

Unbolt the outdrive and pull it of the shaft comes with it!! No need to pull the motor!

the shaft goes thur the back and into the engin coupler.

There is a berin in the hole after you pull the outdrive called the Gimble berring.

Yours may be differen a bit as this is just a exsample!!

Macos correct in saying simply to pull the outdrive. You really don't want to pull the engine, you will need to realign the engine when you reinstall(a bit of a pain in the arse). Outdrive pull no big deal. I am not reallly sure what the steering fork bushings are.
