We still need to know, as least I would, what is wrong with the old
motor and can it be fixed. Sometimes throwing a lot of $$ at a problem seems to be the accepted way of doing these. But often times a little bit of physical and mechanical effort on the part of an owner can get the job done for a lot less $$.
I have a 1941 Ford 9N tractor that proves my point.
If the owner could at least remove the
engine, and take it to an engine rebuilder that would be a good start. Then the problem could be determined and costs calculated.
Just mark all the disconnected
parts so you know where they go back. If the
boat is in the puddle make sure the prop shaft can not slide out,
plug the
fuel line and secure it higher than the tank, and make sure the
water intake is not leaking. Disconnect the
battery B4 any
work starts.
