Packard V8 boat motors in Packard Posted February 28, 2013 55PackardGuy -How can a single-engined boat with one prop be "counter-rotating"? ( jk )Also, not all boats (runabouts) are right-hand drive.....4 of mine are left-hand drive, 2 are RH.Your speculation re RHD sounds good, but I really don't think there is a definitive answer. And, the usual reason to take the drive off the front of the motor is to get the motor lower in the hull (oil pan to front 'stead of rear), rather than for prop rotation reasons....JamesJust looking at this interesting old thread and realized I'd failed to respond to the author's last post. Since the thread gets lots of "views" my aversion to loose ends compels me to reply to James' comments:A single-engined boat with one prop can have a "counter-rotating" engine in the sense that the engine is rotating 'counter' to its original design (RH instead of LH from the perspective of the driver).I'd be curious to know if left-hand drive boats tend to also have LH rotating props, for the same reason I gave earlier for right-hand drive boats having RH rotating props-- to "lift" the driver clear for a better view on initial acceleration.The "usual reason" to take the drive off the front of the motor may not always work to lower the engine because of oil pan clearance. It depends on the pickup location and also the type of pan. For instance, the pan on my Y-block is flat, and the pickup is in the rear, thus there is no advantage in taking power off the front of this engine. It wouldn't place it any lower in the hull and would require re-positioning of the oil pickup.
