    Just wondering if you could post some more pics of the inside of this boat. I seen it at state last summer but did not get a chance to get close to it.

    Looking at this picture makes me wonder how you'd ever fit a third motor back there. What am I missing? Even if you widened the transom there's not much space left. Are these new motors wider?

    I'll have to take some inside pics, will try to do it this weekend since it is in my driveway ready to pull skiers next week. Have to also pull the jump across this weekend.

    Triple big block Evinrudes typically need jackplates to make them fit. Triple small blocks or triple Optis will fit without jackplates. I know Janesville prefers using jackplates and maybe Edd can expound on that.

    Must-Ski Motors,

    Is Madison running BRP Big Blocks on their triple? We put jackplates on because I didn't know if I could get the 3.0L's on the transom. And we still had to modify the wings to make clearance for the steering. Then we found that you can use the jackplates to help turn the big pyramids.

    Have you seen big block triple's on any of Pete's boat? I know he made more clearance and the transom looks like it's farther back than Tom's.

    Mad-City's motors are 3.3L 225's I think they are on 6" static jack plates. The big block BRP motors are really wide, something like 23".

    I have not had a chance to play with a new Dyna-Ski much, rigged that one for Lake Mohawk last year and did some measuring. The problem I see is that regardless of whether they fit on the flat of the transom, the hull starts to curve up and you might need a jack plate anyway to get clean water to the gearcase. They are talking about building an "extra" boat for this summer, and we have 3 big blocks in our club (twin and a single) so I would happily volunteer to do some R&D.

    Side note - these Verizon wireless access cards are sweet! I'm in my car waiting for a meeting.

    Here is a view of the transom/splashwell:

    That's a decent cylinder index! And it's just the boats!
