looking to buy a used axial flow SD231. I realize this is a shot in the dark but there's that ultra slim chance you might know a guy who knows a guy. if you have a SD231 and would ship it to Indiana im buyin. pms or txt welcome (812)-569-0507

Your question has been posted on three jet boat sites.

thank you very much. im on meanchicken that's it.

don't mean to hijack but whats different about the sd231? everyone here that runs AT uses sd209 is it a different engine or a certain type of boat or what just trying to educate myself

Just asking also... Idk much about em but on american turbines site the 231 is leaps and bounds by far the most expensive thing on the website. What is special about it? Just curious

thanks Bill. An American Turbine SD231AF is a 3 stage Axial flow pump. this means it builds higher pressure and lower RPMs. The 231 is a 9" pump yet its capable of moving more water than a 10" given its design. Im told I need a small block motor exceeding 400hp and it would be turning around 3700-4000 rpm and capable of moving 5000lbs 40mph.

All Berkley, Jacuzzi, Dominator, Legend, and the American Turnbine 309 & 312 are all mixed flow single stage pumps. Basically all the same principle design from the mid 60's with a few different variations of bowl sizes and impeller design. The biggest downfall to using these is increased required HP to go fast or to move a load increased RPMs and restricted intakes that get clogged easily. Although I can rebuild one of these older pumps for 500ish and they appear easy to maintain and fix the added RPMs(4-4750) and HP(450-700) usually require a big block(455,460,or 454).

By spending $15k on a axial flow pump like a American Turbine 231, Scott 812,852, or a Hamilton 212,213 it will allow for a lighter weight smaller motor using less fuel and turning less RPM.

I am trying to build the next generation bowfishing boat from scratch, one that doesn't care about weight, isn't loud, and can run shallower than a typical outboard powered boat and use less fuel. A boat that is much safer running in unfamiliar waters in day or night even though its going to be on a extra large scale. Im pulling out all the stops, im way out of my comfort zone researching motors and pumps but learning curves never scared me.

15k on a pump? Holy chit, I'd buy the cheap pump and build a turbo Ls to make up for the power
