Looking for top speed on a 730 or 733?

[RyanPratt]

I am looking to build a 733 OB with 2x 250mercs and wanted to see if anybody out their had built such a rib and if so what the top speed was? Any tips or tricks would be great!

you would have been the first person I'd ask that question to. :-) What speed do you see out of your with 2x175?

And I thought the twin 175's were scary fast?

A friend is running 2x150hp two stroke yami's on a H733 (full flotation aluminum bracket) and can hit 51-52 mph depending on conditions and load.

Ryan - my 36' Nautica with twin 225 Yamahas tops out at 54mph, with the combo that you're looking at, I'd say 68mph would be about right......until the blowover.

I would be a good guy to ask . But im always looking for info from those who have gone before, so i can learn from their mistakes. We run the 730 with 2x175's at around 43kn. and the new 28 with 2x225's around 48-50 kn. looking to get around 65-70kn out of this one. Saw on this forum once some one who built 2 willards wit porta brackets and 2x225's i thought... Was hoping for some tips. I am a bit..... apprehensive with the hull/waterline/weight and 500hp. This is a build im helping a friend on. I would never(probable) need that kind of speed, as the only person i would trust to drive that boat would be me!

On a 753OB we've delivered this year with twin Yam's F200 we reached 52 knots (59.84mph), top speed with full tanks, gear and crew.

I can't imagine a 733 with twin F250, what a beast it would be. Do you have the intention to add a transom extension to compensate the outboard's weight?

Please, please please start a thread on that built if it happens. I want to see that.
