It depends on motor weight and type.

Yes, you are right. And I have decided that I need to determine the
horsepower of the outboard engine first, then I can find out how much
it weights, before I can decide on the issue of mounting and
dismounting it.

My tiller 25HP is about has heavy as I want to lift,
without help. I can take it off my boat in 10 minutes
with an engine hoist.

I will make a note on this. Thanks.
