Re: Storage?
I always thought that it would be nice to have a (from the manufacturer of the boat, preferably) peg with a rubber shock absorbing base back there to hold a spare prop. With a nut or some sort of pin to hold it in place. I'm kind of paranoid about getting stranded out somewhere.
On a related note, hit a submerged (as opposed to one up on land?!) stump idling along and found out that the Mercury Flo-Torq II system works as advertised! Saved my prop, saved the foot of the motor, but I had to limp back to the launch (8 miles) at a max of 6.7MPH! Next time, the spare Flo-Torq will be in the boat, not in my truck! Luckily, the weather was great, no storms, and there were few boats out doe to the 98 degree heat, so it was a warm (close to sunset, not in the heat of the day), leisurely cruise back to the launch. 52+ down to 6.7 is tough to handle!
Thus the paranoia about the spare prop!
