South bay duckboat

[keith white]

Hey guys, I have a question for anyone familiar with this boat. I have a 2 stroke 9.9 Nissan that has seen better days and was wondering if anyone has put a mud skipper twister 13 hp kit on one ,or any mud motor for that matter. Any information or opinions would be appreciated thank you , happy new year!

I own a SBDB as do most of the guys I hunt with. I've never seen any type of mud motor on one. We all run 15hp engines. My gut feeling is that a mud setup wouldn't be good on a SBDB.

Would the driveshaft even clear the motor well?

Paul Mc, can correct me, but the SBDBs were designed to run with the bow up and elevated when under power to offset their low freeboard in chop and rough conditions. Mud motors are surface drive set-ups and VERY heavy. I suspect too heavy for a low displacement hull like a SBDB.



Moral of story: you have very limited boat control with that much surface area exposed to the wind and very little displacement. How a SBDB would handle, set-up so stern-heavy would be likely a bad idea

Exactly.. And while it is a displacement hull, when it's calm, it really does plane off especially since you can manipulate your throttle and where you stand in the cockpit. So when I lay on it to get going, I'll step forward and lean, then you'll feel the boat react, then you can lean a little more rear and dial in your throttle to find a nice cruising speed. When it's rough though, absolutely, just let the boat do the work. It's funny how hairy it feels, but then you look over at your partner in his boat going through the same thing and he doesn't look so bad. Love the boat, but no mud motor.

Eric makes an interesting point, too, I wonder how much of a steering arc you would achieve without having to elevate the motor or motor board... ?

Thank you guys, that's was what I was thinking but I don't know much about mud motors. The price is good and being air cooled would be nice. The motor well is so small that I don't think a newer 4 stroke would work. Thanks for your help
