My Honda 2-hp gas cap is restrained only by a flimsy little plastic "tee" that sticks into the tank - it can be pulled (or knocked) free with only the tiniest of effort. Whoever designed it should be summarily excoriated. It would be better to have no restraint at all, so that people wouldn't be tempted to trust it. I NEVER rely on that to keep my gas cap when I'm refueling on the water. Probably it would be wise to carry a spare cap, because removing it and setting it down somewhere while you refill carries its own risks I suppose. Knowing me (and I do) I probably won't get around to ordering a spare until I finally really do lose this one into the water, however. It would not surprise me in the least to hear that people had lost their caps.
A heads up for the M-15 crowd. I have seen several posts on the Potter sites about the Honda 2 Hp motor and lost gas caps. It may be a design problem or operator error. I suspect resting a large fuel container on top of the motor would pull the cap loose, but I do not have the boat at home to look at it. Of course the cap sinks, so it is not possible to tell if the restraint was broken. It is not clear to me which vintage motors have the problem.
