Props for Tom Cat

Thataway is lift kept, and no bottom paint. At the upper range, this will definately make a couple of knots difference. Also engine position and weight.

I can only speak to the Suzuki vs Honda. The Suzuki 150 and 175 are built on the same block. The Honda 135 and 150 are one the same block. I don't have the displacement at my finger tips, but I believe that the Suzuki is slightly more. Also the prop is larger and with different gearing, has a greater pitch--all of these factors will make the Suzuki faster than the Honda..but only by a few knots, and there maybe a fuel use penality for the speed.

Sorry Warren , I missed that one . The Suzuki had the biggest displacement [513 CCs bigger than the Honda]and the high torque gearing [ big prop,more pitch,spinning slower]. Thats what makes it the fastest . So far for us ,trouble free. The Yamahas are 2670 CCs and much punchier than the Honda from idle and also trouble free. The Hondas are probably the most fuel efficient and the only one of the three that has variable valve timing. It comes alive in the mid 4000s when the timing changes but are noticeably weaker in the low end . That matters to some folks ,but not others .Its certainly not critical on a C Dory.They are also trouble free.I fish on a boat with a 150 Honda and it continually amazes me how little fuel it burns. We work on them all,sell them all ,and like the ability to offer the choice.I would happily own any of them . I might be a little partial to Suzuki though.......
