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, we offer a great alternative! We convert the MPEM, which might be easier than finding a new one. It's cheaper than replacing the MPEM, and if future issues arise, easier to replace. Also, the 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.

Fresh water only used OEM SeaDoo MPEMs, variable trim system, VTS, jet pump housing, crankshafts, water regulators, hoods, props, seats, LCD, ECU, ECM, VCM, rave valves, exhaust hoses, oil tanks, gas tanks, fuel modules, fuel pumps, pump nozzles, exhaust hoses and exhaust baffles.
Warning: The neutral safety switch must be bypassed to complete the conversion. We are not liable for an accident if you bypass the neutral safety switch. On the SeaDoo Challenger 1800, the low fuel warning system is also disabled.

We only convert 1997 and older SeaDoo MPEMs. Panel style MPEM models from 1998 and newer can not be converted due to SeaDoo 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 as this is a difficult task.

MPEM Pricing: Due to market fluctuation in MPEM availability, we can not list prices for each MPEM. Please call us to get the specific SeaDoo MPEM price for your model.

MPEM Testing: Many shops and SeaDoo dealers blame the MPEM and try to sell you a new one, or an expensive part. SeaDoo doesn't sell testing equipment, so it's a trial and error process and some MPEMs do not work on 2-stroke engines. We can tell you many stories of customers saving money by not allowing the shop to make this costly mistake.

OEM SeaDoo engine cases, pistons, cylinders, heads, crankshafts, head assembly, main bearing kits, ignition coils, wire harness, valve covers, intake valve, counter balance shaft, flywheels, stator, male connector adapters, camshafts. We have parts 1988 to present for SeaDoo GTI, GTX, GTX 4TEC, RXP, RXP X, RXT, RXT-X, XP, XP DI.
