    Brand New Mercury Optimax 200

    Hello all, hoping I may get some feed back here. I am wondering if anyone has installed a new 2016-2019 Mercury Optimax 200 into any older Mercury M2 installed Sea Doo boats. I cant get a straight answer from Mercury or BPR and dealers are less than helpful. Any feed back is apreciated

    I have a "new to me" Merc 240 EFI in a 2001 Seadoo Challenger 2000. My second Seadoo with this engine (first was a 2001 Speedster). I was running it in open water for the first time a couple of weeks ago and it died in middle of bay. It had been running fine for an hour or so but just died...
