Is it even possible to do sub moves with the new speedsters? I realize it is VERY hard on the drive train, but it seems nearly impossible to do because of the stops on the controls. Aside from hitting a larger boats wake brodside. Its just kind of fun to see the faces of unsuspecting passengers.

personally i cant see the point of submerging your boat - apart from the obvious safety risk to you and your passengers, in the speedster whcih is a very lightweight boat on the trailer (600kg) and even less on the water (200kg approx) - bear in mind that a 2ft wave or boat wake will be heavier than the boat and could turn you over, i get the idea of the fun thing - just be careful -here in the uk we boat in the sea and the idea of submerging the engine in salt water is madness - i spray all the metal bits in my engine bay with seadoo lube after each go - if i didnt in salt water even the aluminum will corrode - doing sub moves just increases the problem. i know that some of the water goes through the scupper valve, but the air intakes at the rear may fill your engine bay also - have fun just be careful

YES DAD!

Yeah, what he said. I too would like to know how the sub move is done (only in the interest of avoiding them of course) on a 150 speedster...

After researching the subject, I have determined that Sea-Doo redesigned the reverse gate in a way that does not cause the bow to sink. In my experiments, I zip along at speed, drop the throttle, pop the gate into reverse, and throttle back up. No Sub-move, but a flashy power brake, lots of water shooting out the sides and 40 mph to stop in 3 boat lengths.

Agreed with the reverse drop at speed its fun and could potentially help to avoid an accident . Good bit to know just in case.
Also thumper I live on a freshwater lake so no corrosion issues here. I couldn't even imagine takeing the lil boat out to the big waters. It gets pretty choppy on my lake and sometimes I park it till it calms just cause I'm afraid I might crack the glass

Crack the glass??? If a boat cannot take a little pounding, what good is it? Ok, ok, the boat is not really made of glass. Your boat is made of plastic, reinforced with glass fiber. Glass fibers are very strong and quite flexible. Some Navy boats (minesweepers) are made of fiberglass, and I'm pretty sure the Navy sails in choppy water.

I've got the same boat and have not been able to do sub move myself. Stopping quick is pretty cool though.

Carefull with the power breaking as well. My reverse gate broke off and had to replace it myself. Actually the cable broke due to a design flaw and the gate didn't lift up as it was supose to do. When I gave it gas the jet blew it off and broke the mount. The cable broke because salt water was getting under the shifter and dripping down the cable. Couldn't lube it because of the way it is bolted to the boat. Didn't see the condition because it's not in a serviceable location.
Reminds me, I think I will take the throttle control system out and lube it up before I go out for the season this year.

New owner of a used Sportster 4TEC SCIC here. Thought I would show what happened to my purchase. Bought it when the weather was cold, only started the engine, didn't get to go for a test ride. First time out several months later, everything was fine for about an hour. While making a left turn at about 25-30 mph, there was a loud bang and the reverse gate was gone. The attached pictures show more of what happened. Reverse gate gone, support bracket broken in two pieces, both reverse cable ends bent, the shifter base where the reverse cable was held also broken. Fortunately the reverse cable still held the parts where it was attached but still required a laundry list of parts. During repair, it became apparent that there had been previous work done and must not have been done correctly, I suspect that the reverse gate was not locking securely in the forward position. Anyway, the final tally on parts was right at $1000 (a new shifter was half of the cost since you can't buy the base except as part of a complete assembly), without any labor. I was fortunate that I was able to have a friend that was familiar with these boats to do the repairs so I didn't have to pay for labor. Just thought folks might be interested.
