Now I have 3, an 85 horse and a 140 horse Evinrude, also a guy just gave me a really nice 115 hp Mercury 115 “tower of power” . Yes,... gave me. Though obsolete,these 2-cycle engines are mechanically sound and trustworthy.

I’ve found another 30’ r only this time it’s a tri-toon., minus an engine. For doing a lot no range river cruise (approx 300 mile 1way) I’m wondering which power would best be suited between the 115 merc or the 140 Evinrude.
I really doubt one would be more economical than the other. But seeing I’m not paying forvengines there’s lots of room on the card for fuel.
Decisions decisions...

Assuming all else is equal go with the 140. That tri toon will go if
you goose it hard enough. I see tri toons around here with 300s on
them. I am guessing it has lifting strakes.
