Outboard set up advice.

HAHA Funny you should mention that.My friend has an old 6ohp Evinrude,that I'm considering.We gotta weigh it when I get close to starting the boat.The current prop I believe is a 10 inch but you can tell it looks small.He brought out one that he took of his pontoon.That sucker was the size of a basket ball or maybe a little larger.To me,it looked large for an outboard prop.He says if that don't push my boat nothing will.I couldn't help but laugh.The thing looked huge.Maybe if it was on an engine that's hanging off the back of a boat,it would look a little more usable.

 

60's had relativley small gearboxes if you are talking a 2 cyl version.
Not really designed for pushing a non planning boat.

 

but if it is a three cylinder 60hp evinrude go for it
i've used a ton of these engine in the califonia delta on houseboats from 28ft to 56ft just about all of these used a 14x13 or a 14x11
sorry not to jump in sooner been away
the fly by wire i was thinking of is mather micro command
this is a wire system to a box with electric servo motors controlling cables from near the engines

 

That's about the same reason I asked for file of a bigfoot engine... in a thread not too far away from here...

As you see, propeller is also bigger, they are also geared differently, making it a bit stronger against wear from the gearing "klank"..
Seem to be a right choice for an outboard engine intended for sub planing speed.

btw, since the gearing is different, the gearbox is normally bigger, increasing drag.... you can't win them all.......

but I still need a dwg dxf, stl, sldrprt or whatever file......
