NOTES: great sound + low fuel consumption= happy wallet The boat is powered by what is rated at a 100 HP, 170. Being in a boat the engine must have enough low end torque to get the hull on plane( or pull a recreational skier). Once on plane, the engine pretty much has a constant pull (they dont coast). The engine configuration is a little different than your normal auto. It is a flywheel forward setup, where you can actually see the flywheel. I called an old Correct Caft parts guy I know in FLA this morning (not many left that know the 60's boats). I asked him about the 170/marine conversion. He said the long blocks pretty much got sent to "Interceptor" in a stock, of the shelf configuration. Although he couldn't give me the specs, he was pretty certain the cams were stock, like a car would have used. Especially since all they did was physically turn the motor backwards in the boat. The boat had a 12 pitch prop when I got it. However we hardly ever pull skiers with it, so for cruising Ive been running a 13 pitch.prop. As far as the drive, being a straight inboard, this just runs a 1" tapered/keyed shaft, so most 12" inboard type props will work. The dizzy is a Mallory. The exhaust manifold is aluminum alloy and is water cooled.
