SeaDoo MPEM Test Repair

MPEM Testing, Repair and New Sales.

seadoo mpemsSince 2004, Westside Powersports is Your one stop shop for everything SeaDoo MPEM. We test, repair and replace ALL MPEMS with with Dess key programming for ANY SeaDoo MPEM XP, ECU, LCD, ECM, VCM from 1988 to present.

MPEM Dess Programming: We also own a programmer and have made harnesses to program ANY (boat OR PWC) MPEM without needing the machine. That means you ship your MPEM and we test, DESS key program, or program multiple MPEM’s to the same key, check info and hours, and set the timing setting on all 787s, and more.

MPEM Pricing: Unfortunately due to fluctuations in availability of MPEMs, MPEM 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 dealers blame the MPEM and try to sell you a new one or expensive part. SeaDoo didn’t sell equipment for testing, so it’s more of 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 from allowing a shop to make this costly mistake!

MPEM Conversions

Do you have a 1988 to present SeaDoo and having trouble replacing the MPEM? Your not alone because SeaDoo changes every model and every model making them hard to come and when you do, some can cost nearly $2000.

Here, you find a great alternative! We convert it over which is much easier than finding a new MPEM. This is cheaper than replacing the MPEM and if you have future issues, it is much 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. Riders have dealt with ignition issues on 1995, 1996 and 1997 Challenger 1800, it’s more common than it should be and know that having them separate means not replacing the entire expensive module.

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

Warning: There is one down side to the conversion and that is the neutral safety switch must be bypassed to complete the conversion. We cannot be held liable in any way for accidents due to bypassing 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 1998 and newer can not be converted due to SeaDoo’s proprietary 26-Pin connectors. If your 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.
