Message: [QUOTE="me2, post: 367141, member: 3825"] It takes a ton of power to plow a boat through water. I'd say that the average power useage on a boat engine is much higher than on a (non towing) pickup truck. Its probably the same as a towing pickup truck. The web page I linked has definitions of each of the duty cycles. The high output duty cycle is defined as the engine running at full power less than 1 in 8 hours of use and less than 500 hours of use a year. In my spare time I am going to try to get an ESN for a QSB6.7 480 so that I can absolutely compare the parts list to that of the ISB 6.7 XT 360 and the ISB 6.7 350/800. As it stands right now, there isn't a lot of difference. The heads are a bit different, but I think that is mostly emissions. The pistons, injectors and rods are the same. I'm guessing the reason the QSB6.7 480 doesn't have a lower peak torque RPM is that a) props don't use big torque at low RPMs and b) you can't spool the HX55 at low RPMs. I like it that the QSB6.7 480 is making nearly 1200 ftlbs, with stock components, one of which is the cracked cap common rail rods. So given enough air, these engines are suitable for making that kind of torque right out of the box. I wish my friggin parts were cut ! [/QUOTE]
