Respected, I am planing to mount second Mercury 50 hp outboard on my boat. Dos the second oe have to spin the propeller in opposite direction, or can this be done only with the certain propeller?
Since these engines are from the 70-ties, can I use the props from 60 hp engines, or their (50hp) normal props, and will it pose some special difficulties for the engines or the hull in terms of handling and steering.
