SCOTT WATERJET MODEL 912
• This jet is suited to higher horse power/torque naturally aspirated and forced induction V8 engines such as the 6.2L DI, Raptor 460, 8.1, 8.1 HO, Supercharged LSA 6.2L, Raptor 575, LT4, custom stroker LS engines, big block Chevs (572) and some diesel engines like the Mercruiser TDI 4.2L.
• The 9.1 inch two stage is ideally suited to engines that have high torque and horsepower characteristics. These engines have very impressive and aggressive power deliveries which many jets can't handle. The 912 is an awesome jet that couples superbly to this type of engine and ensures maximum performance. They have excellent throttle response and utilize all the power that these type of engines can produce, plus have a wide operating RPM range. The two stage is very rugged and has a high tolerance to cavitation, as with all of our two stage jets they will operate with substantial trash in the intake and have unmatched grip in white water. An excellent choice for the more aggressive and bigger boats.
• This jet was developed for use in bigger river boats to fully extract the power available from the larger V8's and it offers unrivaled performance in its class.

SCOTT 912 / HJ212 SHOOTOUT
The Results
The outcome exceeded our expectations with the 912 significantly outperforming the HJ212; providing more grip, more push, more lifting power, better load carrying, better-cruising speed, and ability to utilise the available capabilities of the 6.2l LSA fully. The test boat was a 22ft HCM @ ~ 5,970 lbs.

Key Observations of the 912
• Higher cruising speeds at the same rpm. More range. Less travel time.
• Carry bigger load. More equipment to your destination and back.
• Extremely resistant to cavitation under all load and throttle conditions giving confidence in big water, and under tight maneuvers.
• Lifts 60% more load onto the plane up to ~ 42 mph.
• Lifted 3 Barrels more ~ 1,455 lbs more (8 Barrels compared to 5 Barrels).
