Re: direct drive

Many different configurations. I think the terminology should help communication. Firstly ,straight drive (the usual) V drive (engine in backwards) and Z drive (like sail drive and azimuth) The reduction ratio (engine RpM compared to prop RPM) is a function of the transmission . No trannie? direct reversing engine or fully adjustable prop or no reverse .Each system has pros and cons in different applications Improvement in that paddle wheels are not common any more. I just noticed Faster beat me to straight/ direct bit.
