Thanks for the feedback.

Docking at 1000 rpm would be a challenge for many. On my setup (OMC-Cobra) they have an electronic module that causes the engin to stutter to almost stall while shifting gears. This was to overcome a clutch design problem. Long story short, it normally idles at 700 and drops to like 500 in that shifting phase, which is actually quite brief, just long enough to ease the load on the gears while the clutch dog swings to the opposite side. Having said that, any cam that will knock the engine dead in that brief timeframe won't do at all. I have the original cam grind specs around here (somewhere?) and am only looking for a mild grind difference (I think). I hope that boring and stroking will acount for some increase in mid-high range torque. Gotta keep in mind that this thing must be able to sustain a 7000 pound boat on plane at upwards of 4000 rpm for hours on end. Translate that to a "wheeled" application and you might equate it to running in a tractor pull for 2000 hours before it fell apart. If you equate it to gas consumption, I was burning 17 "gallons" per hour at 25 mph at that pace with a stock mill. This isn't going to be an easy task for me.
