How would a early 70's OS Max.20 compair performance wise (hp/rpm)to the newer engines, like the OS CVR.15 or even the cheap OS CV.12. I know the newer engines are rated at .56hp for the cheap CV.12 and 1.2hp for the CVR.15, and both these newer engines are rated for up to 36,000 rpm's with peak hp around 31,000. Would a boat designed for a .20 back in the early 70's be noticably faster using a new smaller engine?
