I had 70ish hp Pathfinder 5 cylinder in my boat when I got it, just dropped a Yanmar
4hj4-te 75hp in it yesterday. Much smaller.
Thing about Pathfinder, there is one distributor in Canada
that you can only reach by email
. I can't recall
the name but if you read enough Pathfinder threads(don't worry not many) you will stumble up their contact info. Not sure what parts are left or if the company even still exists.
What parts do you need? I may have something on mine sitting in the garage.
