Genius? Negative lol, more like a guy from OMC walked in my office/shop building at our docks in 1978 and signed me up as a small outboard dealer to get me started in the business and all these years later, after all the tech schools and certifications and a whole bunch of hard work with most of the top brands in the business you learn a thing or two about what works and how to take care of people.
That switch is just a cost cutting measure many manufacturer's left out of their watercraft to save a buck, probably the best $11.00 dollars you'll ever spend on the boat and I really like where you mounted it that's perfect.
So what's left, pump rebuild and some wash and wax time and your in business for the year huh?
