    Default Mark 55H

    Does the 55H use a Torrington B1112 or GB1112 on the drive shaft? I tried to use a B1112 and after installing I could not install the drive shaft. There was a B1112 in the gear case that I wanted to replace. I pressed the new bearing back out and it fit the shaft perfectly.
    What gives?

    i think i've had the same prob with the a-b-c-foot. when you turn the shaft does it want to move in or out of the housing. if so then i think what's happening is that the needles are getting shifted out of paralel with the shaft when it is installed. it's happend to me a few times. went round and round thefirst time. finally i decided to put it together and take it for a quick run. then pulled the foot and found that it had straightend out and the shaft turned freely. has worked for me each time. still it's a scary thing to do. hope this helps.

    They use the GB
    Since 1925, about 150 different racing outboards have been made.

    When driving that new needle bearing in, remember to "knock on the numbers" side of the shell--it's hardened.
