Re: Wife at the helm...
hmm... my problem is that my wife is completely lacking in confidence and gets bent out of shape in a hurry. She knows she should know how to operate the boats, but when I try teaching her, (attempting to be supportive while doing it), she takes suggestions/criticisms/directions personally and gets all snippy and then comes out with "then you do it!". By the way, I'm talking about things that just plain need to be done, not really suggestions (like running the blower on the I/O before starting it). I can't imagine how she ever learned to drive a car.
I checked her out on my 15 hp (tiller) she did fine.... She had operated her Dad's 6hp for many years... She took the 15 hp out on her own (once). She managed to miss the order of the startup procedure. Not running, she forced it from F into N with the throttle about 3/4 open (she had shut it down while going fairly fast, don't ask me why). The N lockout bound up the throttle, making her unable to turn it back to the idle/start range (even though she thought she had), then she rope started it. Result was a stuck throttle with engine rev'ing wildly in N. She pressed the stop button, but would always release it before the engine completely stopped, so the ignition would kick in again and it would start over-rev'ing again. Repeat 3 or 4 times until she finally held the button until the engine completely stopped turning over. After, I tried explaining what had happened and why, but she did not want to hear it.... how do you deal with that??? There was/is nothing wrong with the motor... the problem was with the operator. It would be nice if she was competent to bring the kids out to me when I'm out fishing... or take the kids tubing so I could get out of the sun...
Funny... my FIL was the same way.... had no appreciation for how mechanical things worked and tended to abuse things by how he operated them. Must be genetics. He broke the Reverse lockout on my then new car (manual transmission) when tried to move it when I was out of town.... It was hard to shift into R (lockout), so instead of lifting the collar on the shifter, he used 2 hands and kept ramming it into R until it finally went in and stayed (=broke). Gee thanks.
Your "problem" is where I'd like to get to!!
