Seen this Durajet on Ebay :Cool:
2. 65-75% efficient in HP, speed and fuel consumption.
New Yamaha Gear case + Installed DURAJET + Imron Acrylic Enamel.
(ENGINE IS NOT INCLUDED)
See PREMIERENGINES store for complete engines with DURAJET.
This engine is available long or short in our store.
Will fit 1989 - 2009 YAMAHA 2 stroke- 2 Cyl. engines.
What is DURAJET?
1. A safety device that has been in use with the US military and first responders since 1991.
2. Utilizes 95-100% of engines HP.
3. Produces 10-15% more torque
4. Provides operator better performance in terms of hole shot (50% faster),
tighter turns, no ventilation on turns.
5. Reduces the cost of maintenance (we have sold about 3-4 DJ rotors in 18 years
VS around 1000 regular propellers!)
6. Better confidence while backing up.
7. Less likely to foul. If you do, just reverse the pump.
8. Has factory gears (F-N-R)
9. 5-10% in speed loss expected.
10. If you operate in rocking shallow water, DuraJet is not for you.
Soft and sandy bottoms- okay.
11. Works on any type of boat without a jack plate; Vee , Catamaran, Round or Flat bottom.
12. Works on long or short shaft engines.
If this product did not work, the USMC and hundreds of first responders all over the world
would not risk their lives using it!
SOME DURAJET USERS:
USMC
USN
USA
FDNY
FBI
FEMA
BRITISH ROYAL NAVY
US GEOLOGICAL SURVEY
NASA
PENNSYLVANIA STATE POLICE
AUSTRALIAN NAVY
What DURAJET is not:
1. A low water device
2. Inefficient and rob engine of HP, or high percent of efficiency.
The competitors jet:
1. A low water device (6-12")
2. 65-75% efficient in HP, speed and fuel consumption.
3. If you foul, you're dead in the water, cannot be dis-assembled in the field.
4. Has a bucket that drops for neutral and reverse.
5. Only works on flat bottom boats.
6. Some boats require a jack plate for proper height.
You would need a 3 cylinder 40 to give you the performance of the same
as our DuraJet on a 25 HP engine.
