    115hp 2 stroke on a Stracraft Mariner 21 ft?

    I'm shopping for a new motor to put on my boat, the maximum it's rated for is 140hp. There are very few motors in my market used in the 135 - 140hp range. I wanted to get some feedback from folks on if a 115hp 2 stroke would be too underpowered for this boat? With my old 135hp blackmax i got...

    Mercury Black Max not going above 2000 rpms

    The motor is a 135 merc black max, late 80s or early 90s, not positive. I'm hoping to get some feedback on what may be going on with my motor. This weekend was the first time getting her on the water since last year. Last year she was a hard starter at times, but no real problems so to speak...
