    lost max rpm on 250hp scarab

    If everyone is in agreement that there is something else wrong here and not the warm conditions, I will bring it back to dealer. The dealer tech here says it's ok to lose that rpm that's the problem

    lost max rpm on 250hp scarab

    So 400rpm loss is not normal even in this heat? So what you are saying Is you can lose some boost in warm conditions but not this much correct? By the way thanks everyone for feedback!!! What I'm feeling Is the dealer is just to busy right know to care

    2016 scarab 195ho impuse RPM fluctuation

    Bad gas was my issues, even though I bought rec. gas , I guess you still can get lower octane with it. I'm filling up with shell premium and boat is back to normal. I love this boat, not as fast as I like but it's fine!
