"Thanks so much for having exactly what I needed for my 14 year old Seadoo and the lightning quick shipping!  We messaged for the first time last Sunday and by Wednesday it was already on my ski.  Way cool.  You are an AWESOME resource!"  Nick Smrdelj   <Read more Reviews>   

Beware Aftermarket Mpems! After speaking with many customers, Westside Powersports refuses to stock or sell brand new aftermarket MPEMs. Right out of the box, issues include DOA, faulty gauges, running issues, and other part failures. Even worse, many companies selling aftermarket MPEM parts will not accept refunds. Summer is too short, stay on the water, avoid aftermarket SeaDoo MPEMs!
