Thought more about this overnight and have the following question:
Why is it your resposnibility to make everyones boat safer than factory?
My point is my current key set up does not have any other safety devices installed to keep the kids from turning the key.
My intent on installing your pushbutton start is to keep the key from getting broke off in the ignition, now that would not be safe!
Keep up the good work, not to apply any pressure but the boat comes home in 10 weeks at which time I am removing my key and installing a push button! (Hopefully yours)
