My guess it’d be slightly larger than the Suzuki, but certainly smaller than the beefy Merc. Personally I’d love to see the new 2015 115hp Merc on the back of an X – remarkable they could squeeze 2.1L displacement into 359lb.
I would suspect only the Evinrude and Kermie’s Yamaha 70hp has a chance of mounting without having to modify the back of the captain’s seat – but no where near as aggressive as the MercX at Burrard – and I’m not sure if it has to be that much. Next time you’re by please have a closer look at Bachus – I’m due to cut out a bit of our seat as the DF90 does hit in near full upright (I can’t go fully upright as the front presses down on rudder linkage – I think Windspiration clears better as theirs is mounted an inch higher and has the transom reinforcement plates and wedges – but the linkages are different between the years)
I don’t think you’ll get a NMEA engine readout on your MFD/plotter with carbs, as I know I couldn’t even get an hour meter on our prior 02 Honda BF50.
