Hi riverview.
Pretty easy.
Especially with the engine/ gearbox removed from the boat.
Which is what I recommend.

Drain (pump out) oil.
Undo the bolts around the bell housing of the gearbox and pry apart.
Here is a manual .
However, it doesn't detail gearbox removal.

What is your problem?

Thanks Gary I have , drained gearbox and removed bolts, didnnt want to pry to much as i wasnt sure if I was missing a step. I dont believe engine will pass through companionway with bell housing attached. I appreciate your reply.
