Early morning jet boat questions

[0627Devildog]

You don't need much deflection to knock the jet wash down for surfing. . . . .coupled with the the weight you would need doubt it would give the stern much lift at all.

Where does the white go when the snow melts?

Ooooooooooooooooo

Could something like that be used to push the jet wash under the wave for surfing. . . . ?

That is a great question I'm sure one of the surfers may chime in on that but it sounds like it could.

I agree with @Julian, anytime you would push the bow down (e.g. with tabs), the stern will come up. Could be off-set with ballast no doubt, but you would likely need more of it.

I also agree with @robert843 that the (jet) trim would not be very effective with these big new Yamaha jet boats. That is probably why we don't even see ride plate mods - kind of useless here (but critical in skis). Need big trim plates to do that.

Don't get me wrong...I've love nozzle trim cuz even a little downward angle would improve the wake....

Upward would be a blast but I'll BET we'll never see it stock.....the lawyers won't allow it...

Hopefully @jcyamaharider can chime in. I'm not certain diverting the jet down would improve the wake. Has anyone tested that, it must have been tried? Wake wedge just smooths the whitewash and pushes it down, right?

Most certainly I would LOVE to see nozzle trim on my boat. I was just talking about this the other day and I think it could be really effective for watersports. The wake wedge essentially does what nozzle trim would do, which is push the jet blast under so the water that converged from the side would go over the jet blast.

maybe @Bill D can chime in... his throttle and bucket is on a separate control... if you just pulled down the bucket for slight deflection...I would imagine it would create same effect as a trimming down

I think I understand!
One would almost want to have an independent (dual) trim control. That would enable trimming one side at a time to achieve delayed convergence effect, one could even potentially swap sides that way.
