    Steering shaft removal

    If you use a slide hammer be careful not to shear off the snap ring groove. First try using a crow bar to get behind the gear and also driving it in and pulling prying it out. I can feel your pain, I have had my share of those binding steering shafts.

    Steering shaft removal

    There is a slotted head screw on the drum that the cable wraps around. if that is out then you just have to keep rotating it back and forth while pulling/prying and it will come out. There is a plastic bushing in the housing that corrosion builds up under which causes the shaft to bind.

    Boat Names

    The previous owner of a 24’ Campbell I once owned was at a “Secret Santa” party and ended up with a pair of women’s panties. He put them on and the ladies commented, OH HE is SO SHY! Thus the boat was named. “OH SO SHY”

    1986 Bayliner Capri AQ131a, timing belt intermediate pulley is off position

    Another prop slipping thread

    Once the dog is locked in any gear there is no way it would slip. I am bettering on the drive coupler. Especially after the propeller has been ruled out. Full power starts pulling people really puts a lot of strain on the coupler. Upper or lower gears do not “repair themselves “ after the...

    VP 280 no reverse

    Put the control in neutral, remove the cotter pin from the brass trunnion. With the drive in neutral rotate the trunnion until it centers in the stainless lever. If it still does not move enough for reverse then the cable itself may be the problem or the control box.
