BEWARE of aftermarket SeaDoo MPEMs! We have talked to many customers about brand new aftermarket MPEMs dead on arrival, running issues and other failures. We hear horror stories about companies blaming your SeaDoo and refusing a return or refund. We feel so strongly that any aftermarket MPEM we receive goes directly into the trash. As a result, we refuse to stock aftermarket MPEMs. Summertime is too short, stay on the water by avoiding aftermarket MPEMs.
Why pay more for less service and the same MPEM? All we need is the MPEM while a Dealer needs the whole SeaDoo to Dess program the key. If you live far from a SeaDoo dealer or they want a huge price, keep reading!
