I'd love to see the results of this with the 2 engines being fitted on exactly the same hull with same weight etc....
I would guess that the optimax would lead the way from the throttle opening with (marginally
) faster acceleration and perhaps faster top end - the Suzuki feels probably about as pokey as my old 70hp 2-stroke on 5m rib with acceleration I think.
However, what would also be interesting though would be to fill the boats with say 8 people and then see what the difference is.
One thing for sure though is that the Suzuki will be quieter
