View Full Version : Mondo throttle tension adjustment

09-22-2018, 09:40 PM
New to the wakesurf boat world. Just got 2015 Mondo and the tension on the throttle is loose. So much that once you hit about 10 o'clock (looking at throttle) the weight of the handle will weigh the throttle down wanting it to accelerate. Just figure there has to be a way to tighten the throttle tension. Thanks in advance.

Look under the chrome ring around the throttle. I believe there is a set screw on the bottom you can tighten to adjust the tension

Hmmm... wonder if the same can be done to the Supra. Mine is the same, hit a bump and it’s off to the races if the speed control isn’t on lol

this may be the greatest question asked! often have the same thing a broke pilot, i just always set the speed control. i will check this out.

Yep...set screw underneath...uses a hex allen wrench, but I don't remember what size exactly. I keep it in my glove box. However, mine is tightened as tight as I can get it and it still feels a little looser than I would like it. Doesn't fall on its own, but a big bump or an accidental slight bump from my leg and full throttle she goes.

I have tried to tighten set screw at rhe bottom of the throttle arm. it did not add any tension to the throttle movement. I did find this pic in my documents. I can't figure out where the figure is referring. the27757

I did decide for safety purposes to always turn on cruise control. i set it for around 25 mph and it acts like a governor in case i start porpoising. of course, a higher speed is always available for cruising with the simple push of a button.

I called Seastar Solutions which is the manufacturer of the side mount hybrid engine control. Their tech support said that there is a set screw and wedge behind the control unit. He said to take off the handle(make sure you know the position for reinstalling) and remove the face plate and 4 mounting bolts. Behind it, there is the set screw and wedge to increase the throttle brake tension. Once again, here is a picture of the manual. Hope this helps. I will give update after I complete procedure. 27761

Nice info. Should make this a sticky thread.

I just figured it out. You have to remove the throttle lever by loosening the Allen bolt on the bottom of it with a 1/8” Allen key, and unscrewing the small screw for the transmission lockout. Make sure you do this with the throttle in the vertical home position and down turn the lever as you pull it off! Then once the lever is off. You can use a bigger Allen key to slip onto the large hole and pop of the black bezel. You will then see the adjustment Allen key at the 9 o’clock position. You can right this with a 3/32” Allen key, but don’t make it too tight. Then reassemble.

Very nice! Too bad they didn’t put a hole in the bezel to reach in there and do that without disassembly! I know what I’m working on tonight.
Any idea how much you tightened it before you felt a difference?

I think I added a half turn.

Great post. Just to clarify, you start with shifter in neutral? After removing the set screw and center screw, you said to down turn the shifter as you take it off??? What does that mean? Did you leave it in neutral the whole time? Was it difficult to pop off the face plate? My fear would be to break the face plate. I could see problems if the shifter was not put back on in the same place. I am so glad there is a way to prevent the dreaded runaway throttle. Thanks again for the pics and post.

Start in neutral and DON’T turn the handle as you remove it!

Sorry. God damn autocorrect made dont into down.
