In my teens my father had a shitty bow rider and it had the early rack and pinion style steering box that of course never got greased and froze up occasionally. I know how to use a wrench so I took it all apart and cleaned it and greased it and reassembled it on the mooring. Next weekend I hopped on the boat with my girlfriend, let go of the mooring and put the throttle all the way down as any teenager would. About 200 yards later we are going 25 kn and i notice a submerged log at the last second and I made a hard left to avoid it and the boat made a very hard right! We missed the log but discovered the hard way that I had put the rack on the wrong side of the pinion gear on the steering wheel shaft……. Since I was an expert in disassembling and reassembling it I had it fixed in no time. Fortunately nobody was hurt except my pride. Think I still got laid that day too. Wish I could do it again .
