    I think the main cause for our team not selling motors is the lack of effort. For some reason, we have a hard time getting people to step up and do things, which puts a lot of stress on the people that actually do help out regularly. And of course, when the season is over (or even before it's over) those people are spent and ready to get back to a life of their own. I'm pretty sure this is a common problem on most teams, but it's definitely obvious with ours.

    Hi,

    By chance does anyone know the top speed of this boat?

    with 15 pitch 3 blades it is about 43-44. With 17s trimmed up I think it did about 47.

    Not really sure to be honest, I think we've pulled 5 at least with it.

    Sounds pretty perfectly propped to me. What more do you need for a ski boat?

    Hi,

    I was looking at your guys photos on Jims Photos.com and saw you folks had Twin 115HO's on a Dyna Ski. Was there any speed difference between reg. 115's and 115HO's?

    You could probably run 17 pitch props instead of 15s with the 115HOs which would give you 47-48 mph or so instead of the 43-44 you get at 6000 rpms with 15 pitch props.
