From second hand information via Mercury Marine, all their smaller 4 Stokes are tamed way down, so they can sell you newer, more powerful ones later.

I do know the early Yamaha 4 Stokes were "Weak Sucks". BUT THE NEWER ONES SEEM TO HAVE SOME LOW AND AND TOP IN GRUNT.

If there was a package I'd buy it but once you start messing with Cam duration and what not a special tune would need to be made I would think, Simon performance does have a tune for the Merc 60, boosts up low mid range power pretty good, and supposedly adds about 5-7 hp where it supposedly makes around ,68 at 6300 rpm, that puts it over 70.i have been trying to find someone who has used their tune to get a real world answer. It's 650$ and for it to do nothing would be a waste and could buy more props. I have a merry 12x22 cleaver Wich I believe will be a bit big for my boat but if it's tuned it may work perfectly.
