Tunnel on Dory

Post by Baron » Sat Feb 15, 2020 2:09 pm

Gentlemen,
If I build the Little Hunk dory with a tunnel would that allow me to mount the prop a little higher. I'll be using 40-60 hp and was wondering if the tunnel would dependably feed a propellor that was higher and proportionate to the tunnel.

It's looking like the Little Hunk stretched to 21' will do just fine for me and I'm looking to get into the skinniest water possible. Not say'in I will. Just want to be able to brag about it. Plus ya never know..........

Seems like you might get a lot of cavitation. Have you thought about using a jet drive from a jet ski?

Footer, Is that you first inclination? Cavitation?
It was mine also but I wanted to here it from others so thanks.
I don't really need a jet for where I go. Not that it wouldn't be nice sometimes but I want simplicity and economy and will stick with the prop. It had merely occurred to me that it would be easy to put a 3" or 4" tunnel on it and with a transom mounted outboard perhaps raise the motor a bit. I was worried about cavitation when turning or in heavy chop.
