Re: value of my Johnson 9.9
Depending on where you are in Wisconsin, you'll have no trouble finding someone who wants it. A good running 70's Johnson 9.9 will go from $350-500depending on overall condition. If it looks perfect, add another hundred.
Those engines sell almost instantly on CraigsList in the Twin Cities, but if it's a long drive, it may take longer.
They're one of the most desirable engines out there, since there are many smaller lakes with "under 10 hp" limits, and Minnesota is home to countless small boats needing just that outboard.
