Hello everyone,
There seems to be a several questions on what the “River Racer” needs to pass tech.
We are putting together a new page/link for the NJBA website that has all these items addressed.
All veteran racers can answer the questions as to what you need to pass tech or simple check out the NJBA 2005 rulebook to see what equipment is required.
:messedup:
Please be patient as we are trying to address the issue.

Willis and my phones have been blowing up ... give us a couple of days and it'll be on the boards.

Is River Racer the same as Ski Jet?

[BUSBY]

No ... River racer is a new class intended for new racers that would like to start racing w/ NJBA. Guys from the river ... like those 6th street guys in the other thread ... they know they want to come out ... right guys? :devil:

Hello everyone,
:argue:
There is not a simple way to say this, so here it is, "What the Book Says" on passing tech!
TECH INSPECTION
1. Boat registration will not be completed until the boat has successfully passed a technical inspection for the event and class for which it is entered.
2. All boats must be in safe mechanical condition as determined by NJBA Inspectors. This applies particularly to steering, throttle linkage, U-joints, motor mounts and bolts, seat mounts, wiring and fuel systems.
3. On all motor mounting hardware, a minimum of two (2) threads of the fastener must be exposed past the end of the nut.
4. All boats must have a 360-degree flywheel cover made of production aluminum or the equivalent material.
5. All boats must have a throttle return spring, which will insure an idle condition when the linkage is disconnected or fails. The spring may not be connected to ball joint.
6. All boats must have a “kill switch” connected to the driver that will shut off the engine in the event the driver is thrown out of his seat. This devise shall be mounted or release routed so as to disconnect should drivers posterior move more than 18” in any direction from the drivers seat. Steel clips only on kill switch lanyard. No plastic hooks permitted.
7. All boats with cable steering must have a minimum of two (2) clamps on each cable.
8. No fuel tanks will be part of, or attached to seat.
9. All boats must have a fully charged minimum 5 lb. fire extinguisher in the pits and tow vehicle, with a current certification tag.
10. A device will be required on all boats, which will deflect the holding rope over the highest point of the boat. Minimum specifications 3/4 x .049 tubing mounted at an approximate 45 degree angle and attached at both ends.
11. All boats equipped with a parachute shall have an actuating device located in such a position so to be readily accessible and actuated by the driver without necessitating the release of either hand from the steering wheel (i.e., controlled actuating device on steering wheel, foot release, etc.) a back-up manual release must be within easy reach of the driver. All parachutes will be subject to deployment during inspection.
LICENSE REQUIREMENTS
1. All first time NJBA drivers must pass a driving test, or attend an orientation meeting, or furnish evidence of their driving qualifications to the satisfaction of the Race
2. Committee.
3. All new and upgrading NJBA participants may be required to make a half-track safety pass under observation of the Race Committee.
4. To be allowed to participate, all drivers must provide proof of passing an FAA type Class 3 physical, a DMV equivalent, or a current IHBA driverÂ’s license.
5. All drivers of capsule boats must attend a capsule orientation class held by the NJBA.
JET BOATS
1. All jet driven boats that run 145 MPH or faster must have an NJBA approved safety capsule installed.
2. All jet driven boats that run 100 MPH or faster must have a “pop-off valve” or a ratcheting device.
3. All jet boat intake grates must have bolts drilled all the way through (hull) with a minimum 5/16" bolt and nutted on top. Bolts should be steel, not stainless, and should be fine thread.
PROP BOATS
1. All flat bottom boats that run 145 MPH or faster and all hydro boats that run 155 MPH or faster must have an NJBA approved safety capsule installed.
2. All prop driven boats in excess of 100 MPH must have a prop release mechanism.
3. Chrome rudders or struts are not allowed on prop driven boats.
4. All hydro rudders must extend at least 1-1/2” below the prop when the prop is in a vertical position.
5. 2005 NJBA Rulebook 17 of 24
6. All hydro rudders shall be a minimum of 1/2" thickness at the clam shell.
7. All propeller driven boats are required to utilize a safety collar located just upstream of the shaft seal which will prevent the propeller shaft from moving rearward. In addition, all hydros are required to utilize, underwater, a 2-piece steel split safety collar located directly in front (maximum of 1/2”) of the main strut.
8. The minimum prop shaft diameter through the back of the strut shall be 1” unless otherwise stated in the general rules for the class in which the boat would normally compete. All hydros not eligible for a class competing in the 6.50-8.00 brackets shall have a minimum prop shaft diameter of 1-1/8” through the rear of the strut. Shaft diameter on the front portion of the prop shaft may not be reduced to less than 1”. If a two-piece prop shaft is utilized, the coupler must meet the following criteria:
a. Thru-bolt coupler: Bolt must be indexed into the prop shaft. The bolt must be the same size as the hole in the coupler.
b. Split coupler with set screw retainment: Prop shaft must be dimpled with a drill bit that will fit into set screw hole in coupler the full depth of the drill point. Set screw must be secured in the hole.
c. No rifle drilling of prop shaft will be allowed.
9. All prop driven boats are required to have a drive line guard. The drive line guard is defined as being fully enclosed from the V-drive to the center of the rear coupler of U-joint of the engine within 2-1/2” of the flywheel adapter and secured in such a manner that it will retain the drive shaft, in the event of failure. No perforations will be allowed in the drive line guard. Material must be 1/4” aluminum or 1/8” steel.
BLOWN BOATS
1. All blown-injected motors are required to have blower restraints. All blown fuel motors are required to utilize an SFI 14-2 approved restraining device. All blown alcohol motors will be required to utilize an SFI 14-1 approved restraining device. All blown motors utilizing a screw type blower are required to utilize an SFI 14.21 approved restraining device regardless of type of fuel used. All screw type blowers are restricted to the amount of overdrive used and must meet SFI spec 34.1 construction standards. For construction standards and overdrive percentages, contact the Tech Department. This restraining device must be in place at all times when the motor is running.
2. All blown, injected, or fuel boats must have a fuel shut off valve controllable from along side or in front of driver. The valve shall be located between the main fuel pump and the injectors.
There's a lot of info that needs to read and digested. Please take your time to make sure you have all areas in compliance.
We welcome all new and returning racers - "Watch the Light" :supp:
This is all I can do to help right now.
