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!

The area above is always changing so check back often as links are added.

MPEM Ignition Module Service & Reference

If you are wondering what MPEM is in your PWC or Jetboat, look below to find the answer!

I additionally offer a programming service for DESS equipped boats. If desired, you can send your old MPEM and DESS Lanyard to me so I can verify that you aren't trying to get a stolen boat running. I'll then program your lanyard to a new/used MPEM you've purchased from me. That way you're ready to go once you get the replacement part. I also stock Lanyards if you need an extra as well (up to 8 can be stored in the MPEM). I additionally can install the replacement MPEM in your electrical box if desired as well. If interested in any of these services, e-mail me and I'll send you a quote for what you want to do.

Also, I'm in the process of making conversions so you can use a PWC mpem/electrical box in the various Rotax powered boats. This will allow for cheaper repair of the boats defective mpems as well as to separate the boats electrical system on twin engine models so you can get back home on one in case of an mpem failure. So far I have conversions available for 1996 Challenger and 1996/1997 Speedster. The only drawback to the conversion is the elimination of the neutral rev limiting features built into the boat mpems. As long as the operator is careful, that shouldn't be a problem. If you're interested in a conversion for a particular Rotax powered boat model, let me know and I'll see if I can put together a system for you.

I also have aftermarket mpems available for select older models. Check here for info on that.

One more note – I don't have a parts book for the newer Jetboats that use the mercury motor, so if you need an MPEM for one of those, I would have to call my supplier for the part number and availability.
