· The SD-231 is a fine example of modern technology along with many years of experience in the jet industry.

· The SD-231 is totally computer designed.

· Computational fluid dynamics was used in the design of the impeller and reverse bucket.

· Hydraulic reverse bucket with feedback control so the operator would always know where the bucket is by the location of the reverse lever.

· A cleaning impeller design is one piece which allows trash to be flushed through.

· The Stainless Steel Impeller 231 mm (9.0”) is cast from a 17-4ph alloy which is twice as strong as that of our competitor.

· Unlike other impellers our scan absorb a lot of horsepower without slipping, the holding power in aerated white water is incredible and that is out of the box without any “BLUE PRINT WORK”.

· The water inlet block is made from 6061-T6 aluminum Billet plate which is 1-1/4” thick.

· The rock grate is CNC machined from a solid piece of 6061-T6 aluminum so that it is very smooth to allow uninterrupted water flow to the impeller.

· The hand hole cover is positioned behind the transom so that removing the hand hole cover won’t result in a flooded bilge.

· The thrust bearing is upgraded to a large one for more thrust load capacity.

· A changeable nozzle insert to fine tune your boat for every application.

· The steering nozzle has a Teflon o-ring that seals against the housing to make sure all the water is accelerated out through the nozzle insert.

· We offer a hydraulically operated stainless steel ride plate This plate is located off the intake block and is actuated by twin cylinders on each side of the jet, this allows you to control the bow attitude according to the weight on board and water conditions, this works much better than trim tabs that get blown off by the reverse thrust.
