I have a 1999 seadoo GTX that I bought the guy said he fried the old MPEM from jump starting it its dead it does nothing. He also gave me another one with a key but said it was screwed up to I hook it up and the display lights up without the key does nothing else so I am looking for a replacement MPEM/key. What ones are interchangeable with my ski? I look on ebay but cant find any that look exactly the same as what I have?I see some from a gtx rfi but look different? Also there is a 1999 seadoo GTI parts ski near me wondering if that would work aswell? Pic below is what came out of my ski.
