I offer NOS parts for Sea Doo watercraft and my prices are usually lower than you’ll find anywhere else! The part you receive will be in new condition unless noted in its’ description. Since I sell outdated inventory from dealers who no longer carry Sea Doo, the packaging may have dirt on it, may be damaged, opened or missing, but that doesn’t affect the part in any way.
If you need a part you don't find on this site, e-mail me with the model, year, and part you need and I'll see what I can do for you.

Sea Doo Tips

To avoid expensive
electrical system damage
NEVER
jump start your ski
with a running vehicle!!

Change your pump oil
every 50 hours and
you’ll save money in
the long run !

Battery dying in your Trim
equipped 1995 up Sea Doo?
Disconnect your VTS unit.
If that fixes the problem
the module probably has
failed due to moisture.

Every time you have
your engine compartment
open, grab the motor and
give it a pull to make sure
your motor mounts are in
good shape. Broken mounts
can cause driveline and pipe
problems if not caught early!

Save money and time
by doing repairs yourself
instead of using a dealer!

External Rectifier Upgrade for Sea Doo 947 Carb Models

If you’ve got voltage problems on your 947 (951cc) powered Sea Doo, that’s usually due to a bad rectifier. How can you tell if you might have a bad rectifier? An indication of a bad rectifier could be “12V Low” indicated on the display or a battery that won’t stay charged. A battery drain while in storage can also be due to a rectifier problem too. The real kicker is that the rectifier is built into the mpem on ALL carbureted 947 Sea Doos so if it fails, your only option was to purchase a new mpem. Now with my kit you can change to an external rectifier and keep riding for much less expense. This also would be a good addition for preventative maintenance since sometimes when a built in rectifier fails it damages the mpem and if that happens, it would be too late for my kit to help.

What I offer here is a special set of harnesses that allow you to easily connect an external rectifier to your battery and stator so you’re charging at maximum efficiency and output. Another cool feature would be if you’ve bought one of these as a preventative measure since if for some very unlikely reason you have a failure on the external rectifier, by unplugging the adapter harness and plugging the stator harness back into the mag housing you’re back on the mpems internal rectifier.

My kit includes the special harnesses and a really heavy duty 4TEC rectifier that I modify to plug into my special harness. Installation is simple taking only a couple minutes and no special tools. Additionally, when I build my harnesses I solder the terminals to the wiring as well as crimp them to ensure the best electrical conductivity and strength. Once this one’s installed, you’re not going to get stranded again due to a bad rectifier and dead battery!

Works with the following 947 powered Sea Doos…

EXTERNAL RECTIFIER KIT INSTALLATION…

Tools needed:

10mm Ratchet with Extension
Zip Ties
Voltmeter (optional)

Procedure:

Remove the seat(s) and any storage containers to gain access to the front of the engine and battery.
Using the 10mm ratchet, remove the bolts retaining the positive and negative cables to the battery.
Using strong zip ties, fasten the new external rectifier in a position where it won’t rest in bilge water (preferably close to the battery) and where it won’t bounce against other components and damage it or other lines, hoses, etc. If you want to fasten it to something with stainless bolts, you should also be able to pick those up at most hardware stores.
It may be a little tricky but next, unplug the magneto connector located in the front of the engine under the pipe.
Un-roll and stretch out the kit harness with the plugs for connecting to the magneto housing connector. Plug the harness you unplugged in the previous step into the kit harness and plug the other end of the kit harness into the magneto housing plug. Then thread the other end of the kit harness to the rectifier and connect to the proper 3 connector rectifier plug.
Un-roll and stretch out the kit harness with the terminals for connecting to the battery. Plug the 2 connector black plug into the rectifier then run the cables to the battery.
Reinstall the 10mm battery bolts retaining the battery cables with the new rectifier positive and negative terminals.
If desired, use zip ties and retain the new harnesses to existing cables and/or retaining points to make for a professional looking installation.
You’re ready to run! If you want to check to make sure the kit is working properly though, fire up the craft on the hose and using a dc voltmeter, check your voltage output at the battery terminals. You should be reading over 14 volts when running.
(If anyone wants to send me pictures of the finished installation with the rectifier mounted, that’s appreciated too!)

Note that as is the case with your local dealer, there is no warranty on new or used electrical parts purchased from me. The reason is that I can’t guarantee some other problem in your electrical system hasn’t damaged your original component and/or the replacement unit. Make sure all other electrical components are in proper working condition before installing a replacement part.
