Do you have a 1988 to present SeaDoo and having trouble replacing the MPEM? You're not alone! SeaDoo changes every model which makes them hard to find, and when you do, some can cost up to $2000.

Here is a great alternative! We convert the MPEM which might be easier than finding a new one. This is also cheaper than replacing the MPEM, and if future issues arise, easier to replace. Also, twin engine SeaDoo models use two MPEMs, which means if an issue arises with the ignition on one motor, you only need to replace one MPEM. Rider's have had ignition issues on 1995, 1996 and 1997 Challenger 1800. It's more common than it should be and important to know they are separate and only need to replace one MPEM.

The conversion is easy, just about anyone can install and get the SeaDoo up and running in as little as 10-minutes. No wiring is needed, the connectors match up to replacement MPEMs, so if there is a problem, it is a Plug and Play replacement solution.

Call or Text for expert service, we confirm you have everything needed, email the invoice and ship the same day free in the USA.

Warning: On the downside of conversions, the neutral safety switch must be bypassed to complete the conversion. We can not be held liable in any way for accidents due to the bypassing of the neutral safety switch. On the SeaDoo Challenger 1800, the low fuel warning system is also disabled.
NOTE: We ONLY convert 1997 and older SeaDoo MPEMs. Panel style MPEM models from 1998 and newer can not be converted due to SeaDoo's proprietary 26-Pin connectors. If you're good at cutting, splicing and connecting wire, buy the SeaDoo grey style E boxes and we'll provide support to get the job done, but it’s not easy.

MPEM Pricing: Unfortunately due to fluctuations in availability of MPEMs, parts and options, we can not list a price for each MPEM. Please call Nick or Jess to get your specific SeaDoo MPEM price.

MPEM Bench testing: Many shops and SeaDoo dealers blame the MPEM and try to sell you a new one or expensive part. SeaDoo doesn't sell testing equipment, so it's a trial and error operation. Also, many MPEMs will not work on 2-Stroke engines, we can’t tell you how many times we have saved customers money from allowing a shop to make this costly mistake!
