    Default Mariner 100HP 4 Cylinder 1988, seek advice on alignment shift shaft cam currently would not shift

    Hi Guys,

    Mariner 100HP 4 Cylinder 1988 -93 (exact year unknown)

    Problem is after changing shift shaft seal (due to excessive amount of water/exhaust oil in gear box, changed water pump gasket, driveshaft seals, shift shaft seal), it wouldn't shift and leave me only forward gear. The reason might be when I pull open the shift shaft bush to replace the seal, the shift shaft pop out and disengaged with shift shaft cam. It's said need to be tear apart all the gear box and do the alignment and assemble again.

    Before I do it, I'd like to seek advice from you all who has experience in that. How I can dismantle drive shaft? propeller shaft, anything need to be very careful at? I'm trying to get the tools to pull the propeller shaft bearing carrier now . Kind of heard some people said need a proper torque to dismantle pinion gear.

    Cheers
    Howard
