How the heck do you guys know how big those engines are???
Anybody want to guess what these are?

Those B&M transmission are really a trick piece when they work. Big warning though. BIG!!! The transmission must be aligned perfectly or you will blow the pump in about 30 seconds. Very, very expensive fix. The crank shaft must be centered in the bellhousing. Have your engine builder do this. Adjustment is done with offset dowel pins. Since you are discussing pulling the engines make sure this is done when reinstalling the transmissions. The first gear is really only for low speeds as it is a low ratio gear. I shifted at around 40 mph. Pull back on throttle, shift and go. The boat would plane off really, really fast with low gear. Those transmissions are a problem with 1000hp. 575ci and blowers you are probably at the limit. If you blow a transmission replace them both with Hubers or Bams. I lost two of them before I gave up.

Cats sit on top of the trailer not in it like a vee, so you will not hit the drive guard when launching. The back of the boat floats up some when launching as well.

Lose the second wheel. Looks weird and could be dangerous.
Brad, Tell us how you are such an expert with these trannies! How do you know they will blow in 30 seconds if not aligned?

Goldman and I blew one in the 35 Motion in about one minute at speed. This is before I bought the boat from Larry. Larry fixed it and it blew again. Turns out we found out it needed to be aligned.
