Re: Non counter rotating twin i/o's?
It's not at all surprising that boats were manufactured with non-counter-rotating I/Os, especially mass produced boats. If you don't see that, you've probably never worked in the manufacturing industry. Mass production is all dollars and cents; I once spent three months on a value added/value engineering team of 6-8 full time, salaried engineers whose only job was to cut $120 per build from a heavy axle production line over the course of one year. If that was my job, and I had the opportunity to quickly and immediately cut $200 per build for a fairly minimal end performance loss, I would of course do it. To not understand that is to not understand mass manufacturing.
I'm not trying to defend the practice, as it's already been well-established that counter-rotating is the superior performance option. But the reason you see non-CR manufactured boats is the same reason Maxum put a 2bbl carb on the 350 in my boat. Cheaper to produce.
