Battery issues, wont go over 35mph

[corydavisGTX&XP]

I took my 2001 GTX out and even when I replaced the pump housing with a new wear ring it still would not get over 35 mph.

When I turned it off it would not start again. I was able to jump it and then it went all the way to 55 until we turned it off again. I know the battery is prob bad but will a bad battery make it not go over 35mph?

First, never jump start a seadoo as you can fry the expensive computer (MPEM).

A low battery and/or bad voltage regulator can cause a lot of weird running issues.

I changed out the battery and do not have an issue starting again but the SeaDoo will not go over 32mph. Any ideas on next steps?

Other than that the Seadoo appears to be working perfectly.

The RPMs won't go over 4700.

As per miki check that it is charging.

I'm going to buy a voltmeter with a 8' cord to measure the voltage as I'm riding it. I assume that I just banana clip the meter to the battery terminals.

I also checked the compression and they are both at 150.

Should I just change out the voltage regulator?

This one goes out to all second and third seadoo owners if yours came with a couple sets of keys. One of the keys has a governor programmed into the key to be used for kids that will prohibit it from going over 35.

When I changed the key it went to 6100 rpm and 55mph.

Oh, and I found this out in the first few pages from the manual which you can download for free from seadoo website.

That's really interesting. Do those keys work on any model year, or only 2001?

I have a 1996 and would love one of the "kids keys" because my lake speed limit is 35 and it'd be nice to not have to worry about throttle position

Only the DI skis and 4-strokes.

I'm not sure. Here is what the manual says on page 35:
The safety lanyard cap specifically con-
tains an electronic circuit that gives it

a unique electronic serial number. This
is the equivalent of a conventional key.
This safety lanyard cannot be used on
another watercraft and conversely, the
one from another watercraft cannot be
used on your watercraft.

However, the DESS brings a great flex-
ibility. You can buy an additional safety

lanyard and have it programmed for
your watercraft.
The DI models also offers a special
safety lanyard — the Sea-Doo LKTM
(Sea-Doo Learning KeyTM) — which
electronically limits the speed of the
watercraft to approximately 55 km/h
(35 MPH) therefore enabling first time
users and less experienced operators
to learn how to operate the watercraft

while gaining the necessary confi-
dence and control.

To have additional safety lanyard, refer
to an authorized Sea-Doo dealer.
If the engine is stopped with the start/

stop button while the safety lanyard re-
mains on the post, it can be restarted

within approximately 10 minutes by
pressing the engine start/stop button.
After this delay, it is necessary to apply

a slight pressure or to remove and re-
install the safety lanyard on the post to

allow engine starting.
