Mercury 5hp Propane Outboard

December 8, 2020 by jim Leave a Comment

It’s been about a year since the Mercury 5hp Propane Outboard was introduced. I figured a year later we would have some solid real-world reviews and a boatload of information on it. There is hardly anything online except for one start-up test from Christopher Di Francia on YouTube. Check out his propane test below.

The idea seems brilliant. The same propane tank you use to fire up the grill, you can now use to power up your outboard. No fuel, no mess, nothing.  Why hasn’t this taken off?

What gives? Why hasn’t propane taken off for outboards? Environmentally it’s a win in my mind. If you are interested and looking for more information, head on over to the Mercury website by clicking here.
