Sub Movin'?

[Peelz]

Still no new boat here...many reasons... but still hanging around. useful info here, boating or otherwise.

One of the things I enjoyed seeing was vids/pics of you guys with jets doing the "sub move" something I considered as a positive for jet drive(no gearbox, instant reverse) I also have a foggy memory of my uncle ('put some hair on your peaches boy' type) doing this in a gold flaked gelcoated glastron. I could only assume it was a jet... but I'm guessing I was 5...6 maybe. I remember the day fondly.

With an I/O all you can really do is come off throttle on a big wake at idle.. I do this by doing a 180, coming off throttle as i cross my own wake....fun. but its not the same rush lol no "sub" just a splash.

I did this last weekend, splashing my boys sitting in the bow. I was idling forward. soaked them and their towels, looked like 2" off water over the bow.... but only required about 30 seconds of bilge pump to remove it.

My wife was tempororaily INCENSED hahah but came out of it. kids faces washed momentarily with fear, followed by huge smiles. -Its happened before, just accidentally crossing a huge cruisers wake.

Now. being that its HER that wants the Yamaha, i explained to her about the sub move, and How jet owners do this sometimes, and that i would be doing it at least once. She looked confused.

so. curious, how many of you do this? and if you do....and have a photo, or video, id like to see it so that I may send it to her. (probably make her more mad but....)

haha i found a couple...


brilliant.


crazy, but brilliant.

I'd like to do it.... on someone else's boat.

People do this on purpose? I've only done it in accident when I thought I'd be ok. I'll punch it over a roller when needed. Look at this idiot.

hahah right! thats one of them. fun but a bit extreme.

 

[Peelz]

not sure id call them all idiots, looks like fun to me, its their boat. And assuming passengers are into that.


found the one i was looking for.... frame by frame is hilarious.

Thank you, I will take credit for that masterpiece. I posted that on my YouTube channel, www.biff.org quite a few years ago in our SeaDoo X20. Before we start a flame party, that was not the first sub of the day, nobody was surprised, or in danger. And the young ones that had to have a life jacket on by law did.

That being said, it was way bigger than we had expected, as I hit the gas harder than the first four as we were "showboating" in front of the cabin. I can't imagine what it looked like from the front.

All I know now is we didn't do any more big ones, just slight sprays over the bow, as I had dropped in a new Alpine sub below that water line a couple weeks later, and didn't care to damage it. I sold that boat this spring after an additional 6 years of use. No damage to the boat at all, as it was designed to take on water and flush it out the side drain from the factory.

Now, I warn the bow riders whenever I turn into the wake to pick up a downed tuber, or boarder, and they don't hardly get a spritz over the bow. My wife has never loved bow riding like she does in our 242 now!

More Shelbyville fun:

You can't do the sub move if you have Electronic Gate controls (e-series boats)....not unless someone like @Mainah figures out a way to over ride their RPM limiter

Just remember you CAN destroy the reverse gate doing those .

 

[Jgorm]

Sorry, no disrespect intended. You won't catch me doing that! Better but a couple of these.

I’ve done a few intentionally, in my first jet boat. The last one cost me a month old stereo and my cell phone. Now, forget about it. Most of my guests and I have smart phones, cameras, drones and water unfriendly gear onboard that we are not willing to risk but it’s a great emergency brake when you need it.

 

[Drift Away]

Ummm....no thank you.

 

[haknslash]

I can just see the flimsy reverse bucket and cable screaming to STAHP

Personally I'd never do it in my boat.. It looks like something I'd try in a rental though

Just remember you CAN destroy the reverse gate doing those .

In actuality, the forces being put on the reverse is no different then putting it into reverse at the dock. It literally takes very little thrust to make that bow dip, you would be amazed. I would bet it would be 1/8th to 1/4 thrust at most.

And here is the bigger kicker on SeaDoo's, you have to run two sticks with one engine. You have to fully close the throttle for the direction shifter to unlock from forward, to neutral, to reverse. So the amount of water flowing through is only from the forward motion of the boat. So yes, there is a fair amount of thrust going through the pump from that, but nothing like what the engines can put out.

Once you move the bucket to reverse, then you have to throttle the engine back up. It cannot be throttled up in neutral, or between directions while that bucket may not be locked in place. You would literally have to throttle it up to full to damage that reverse bucket. And that would never be necessary to perform a sub. It's amazing how little it takes, and the sensation of the bow dipping, and the rear coming up is very hard to describe. Yup, it's not for the folks with expensive gear or sissys on board that need to stay dry.

But your point is well taken, it's more stress on the reverse buckets than what they were intended for, so damage is a logical assumption.

WElp, showed the fam a couple vids, the two shelbyville vids specifically.


Kids, want a jet boat even more. Wifey, less than impressed.

 

[W3bexec]

Showed my wife the OMG Sub move video before we took delivery of our 240. Nope, nope, nope. "If you EVER do that..."

 

[biffdotorg]

Sub moves don't have to be boat-filling. They can be tame splashes over the bow to wake up the family. These are no worse then catching a wave the wrong way. It's also a good way to rinse a spill off the floor

 

[2kwik4u]

Tried it on my AR190...no go. Reverse doesn't have the pull to bring the bow under in flat water.......I suspect I'm doing something wrong.

 

[F.M.]

I've done a couple of tame ones while cutting back across my own wake to pick up downed boarders. Just enough to shock the passengers in the bow and wet their towels. Water drains quickly out the scupper. No big deal.
