SeaDoo 3D (need some help)

[MARKUS]

First of all sorry if this is in the wrong place.(newbie)

I have a customer with a 3D Sea doo when he is doing sharp turns the ski looses a lot of power. Has somebody had the same probleme and what is the cure for this poor customer?


We do need help in Africa

Thanks
Markus

2005 110HP 3d?

2006 130HP 3d?

let's find out which motor you are talking about first and we'll see what we can come up with.

Sorry it's a 2004 3D

He is loosing power or just feels like its not moving in the direction he's going fast enough.

[Shibby1485]

is this coming from the customer's testimony? Or have you seen or ridden the symptoms with your own eyes?

[MARKUS]

I will be testing the ski this afternoon and get all the facts in line for at this stage it is the customer saying this.

I spoke to the importer of SeaDoo to South Africa and they say they also have one doing the same thats loosing power the moment you turn the steering wheel.

Thanks for all replay's

Just by making sharp turns the increased water resistance will slow the ski down considerably and it will feel like it is loosing power. This is especially true with the marginal 110 hp 800 engine.

I would guess that a throttle cable is loose and when you turn the bars the cable does not stay tight.

[ccassone]

I watched a bunch of people riding 3d's and when you turn it slides out easily. The sponsons aren't very good on that model. Who knows he may be turning sharp enough so that the intake in the bottom is sucking air. When you turn or lean the hull tips to the side and the intake is exposed to air, and if you can't stay hooked up to the water, you aren't going anywhere. He could be not hooking up 100% in the turns and that can cause lower speed. Also like stated before, when you turn the hull cuts into the water and there is much more resistance. Tell him to buy the 06 951 di, and I'm sure he'll like it much better.

Ok this is wat we did yesterday:

1: ran the ski in a straight-line flat out for about 800 meters with no problems.

2: ran the ski flat out and start doing a small turn (raduis of about 100 meters) to the left, the motor will start to surge (rev up and down) and you can hear it doing it. The moment you start to go straight again it will stop.The turns are at about a 5-10 deg turn on the handle bars.

3: the above did not happen when doing the same to the right. (The importers of SeaDoo have one doing it to the right also)

4: when we did the hard turning test the ski will be much stronger in the right turns out the water as the left turns.So I think that it also surging at the bottom end I can not hear it doing it.

5: when we did the sharp turning we tryed not to expose the bottom to air

5: placed the ski on the trailer and tried to repeet test 2 but with no luck

6: placed it back in the water redid test 2 and it was still doing it.

I have never heard of this.

Thanks for all the advice and keep it comming.

this sounds like cavitation issue. the 3D doesn't exactly sit level with a rider on it, has a tendency to lean to one side until under way.

being that the symptoms won't occur on the trailer with the ski flat and hooked up to the water keeping the pump loaded and turning the bars means air isn't getting into the pump

ur turning to one side while on the water and your bogging down, rpms surging... do u notice if the rpms surge upward or downward? the RPMS may actually surge up, but the ski slow down....

have you checked the wear ring on the machine already to make sure it's not grooved and pitted? if not, DEFINITELY START THERE... if you already attacked that aspect, i'd be interested to see if an aftermarket intake grate would solve the problem.

another question... where is the VTS positioned when this occurs? have you played with that at all?

[Water4fire]

I would check the Fuel pump to make sure it is working at top performance. I would think that in a turn the added gg's of the turn might make the fuel delivery slow down making the ski hesitate or bog with a week fuel pump! And this might be why it is more prononced in turning one way and not the other. Also you might want to replace the fuel filter.

I will think on this and see if I remember more!

[MARKUS]

I think (sounds like) it is dropping in rpm for when we do the left turn is't running at full throttel.And remember this is not a sharp turn it's a long turn I do not think that there can be a big g-force factor involved.

I will look at the wear ring.

will check fuel pump and filters


Thanks

Check the routing of the throttle cable. I would bet that is where the problem is.

[J3ff]

IF your throttle cable was messed up it wouldnt SURGE, it would go to a lower RPM and stay there.

I would like to back up the other poster saying that something is wrong with the fuel.

Even in a slow turn there are different forces at work. If it was cavitation it'd do it both ways.

It could even be that your fuel/water seperator isnt on tight enough, and when you turn one way it makes it let in a little air, turning the other way does not.

Def a fuel problem. Unless something is restricting the air in a turn?

[Green Hornet]

This is not the only one that I have heard with this problem. Left turn loosing power. What did BRP have to say about it? Maybe this is one of the reasons why they are delaying the release of the 3d di. What ever you find out please post your results. I'm sure 3d owners would like to know although you don't see too many of them acknowledge that they have one. :D

[snakie1]

Does it have a tip over sensor that may be faulty or not mounted in the correct position ???? I have seen motorcycles that have had one of those go bad or start to go bad and they were acting really similar to your problem.

[MARKUS]

We tested every sensor in the ski and they are working.O.T.A.S is working the feul is good.I have checked every piece of advice that has been given to me. Took the ski to the water and it's stil doing it.

If there are any 3D's out there not doing this can you please supply me with the following info:

1: compresson
2: altitude
3: were are you

Thanks
Markus

[MARKUS]

IT'S FIXED AND RUNNING VERY WELL :D

Thanks for all the input and advice.

Thanks
Markus

[Green Hornet]

What caused it and how was it fixed? btw what is the fuel mileage on a 3d? How long can you go with a full tank?

[Green Hornet]

Is the 3d a big seller in south africa?

[Tiplickhahaha]

IT'S FIXED AND RUNNING VERY WELL :D

Thanks for all the input and advice.

Thanks
Markus

What was causing the problem :?:
