Hey guys and gals,

JetBoatPilot has made an improvement to the Thrust Vector system for BRP Powered Jet Boats. This year, as a result of input made by some of the members of this board, we've added a rubberized coating to the cross member (actuator) of our Thrust Vector slow speed steering system.

This rubberized coating was added to eliminate the metal on metal contact being made between the reverse bucket and the cross member during certain operating conditions. Now, with this new coating in place, in the event that your reverse gate does come into contact with the cross member this rubberized coating is in place to minimize the potential for wear and cosmetic blemishing.


Single Engine Thrust Vector Install Video:

(The twin engine version is similar in its installation procedure but the bottom mount sheet metal is a bit different due to the connecting rod that ties the two nozzles together)

If you have more questions about Thrust Vectors for your Chaparral, SeaDoo, Scarab, or Glastron jet boat feel free to contact us through the website as well as through jetboatpilot.com.

Thank you to those of you who were instrumental in seeing this improvement become a reality. Once again we value all of your opinions and will always look to use your suggestions where possible to make your experience with our products more enjoyable!

So you put a rubberized coating on the fins. Lipstick on a pig....... Unbelieveable... even on the video you point out the issue with these, and still no redesign. I think it's time for the rest of the jet boat, and ski enthusiasts to weigh in.

No @ScarabMike we put a rubberized coating on the cross member. The fins are made from starboard material and stand practically zero chance of harming the reverse gate. They also can't come into contact with the reverse gate unless someone rips off the cross member, which I'm sure you can concede is outside the realm of normal operation.

Its the crossmember thats the problem Will. You even describe it on the video. That crossmember is the safety issue.

For these not to have a catastrophic failure that would hinder control of the boat, these fins need to be STATIONARY. Even if you have a 3% chance of touching the "brakes" on the boat its too much. If at any point this happens, you will also loose steering. And if this happens going 40mph, you better hope there isn't any obstacles in front. How can you not see that the issue isnt the rubbing, but what is causing the rubbing. Wow man.

I know for a fact that the cross member cannot travel underneath the reverse gate. We designed it that way after an early prototype did exactly that. Unless there is a different reverse gate which we have not measured I don't see where our fins could be trapped. I will continue to test and if we find that your claim is possible it will be addressed.

Also if you will look at this picture you can see where we've designed in a stop, built into the clamp (note the ramps above the fin pivot points). The clamp is the component which connects the fin assembly to the nozzle. It provides the pivot points for the fins as well as mount locations where we tie in to the top and bottom of the nozzle.

The stops were added to prevent the fins from rotating so far upward that the cross member could get trapped under the reverse gate.
