    Jeez I wonder what it would be like to drive one of those rigs and put it thru it's paces. The acceleration must be incredible.

    Originally yes. Then a couple weeks later they changed them out for 3 225 Pro XS motors.

    These were the replacements.

    Why? I'm surprised they fitted 150 four strokes in the first place. Just didn't perform?

    I also am confused on this. What are they trying to pull with this rig? I understand the transome holes and all but if 3 150's did not do the job would not 2 225's do the same at 450 total? I do know that efficiency wise 1 motor is better than 2 and 2 would be better than 3. Torque and 3 props in the water probably skew that as efficiency would be sacrificed for hole shot power to get a large pyramid off the dock. I cannot tell from the pics but are the 3 original motors the Merc 150 4 strokers? Another question I have is why would someone or a club buy a 20' DynaSki and put 3 relatively low HP motors on it? The DynaSkis are made to handle whatever you choose to hang on the transome be it twins of triples.

    My math would suggest 675 hp.... Not sure how you get 450 hp with tripple 225's:).

    Mark Banovetz asked the same question a couple of years ago. Then he had his twin rig. I'm fortunate to have been in DyneBob's 18 at the 2007 Show Ski Nationals. Mr. Tom Miller stated clearly that while he has been in a lot of different Dynes, DyneBob's pulled harder than any other. Case in point, with four people in DyneBob's 18, I can only imagine what the g force is like with a triple rig. Even with a thousand pounds of ballast in the pointy end and a heavy plate on the transom it has to be a thrill.

    Can any of the former club members comment on the handling characteristics of a triple rig without the ballast?
    Thanks!

    Everything changes when pulling big loads. There is no "hole shot".

    Static thrust is everything. A lot of different ideas have been tried. What you see pulling big loads works. Multiple big two strokes.
