Re: 110cc Mercury outboard is what HP??
My brother bought a 110cc Mercury outboard motor and we are trying to find out what horse power it is. Thanks
If it has "110" on the cowl it is a Model 110, not 110cc displacement, like the naming for motorcycle engines. The Model 110 is a 9.8 horsepower motor with a displacement of about 17 cubic inches, which is about 278 cubic centimeters.
If it really is 110ccs that would be 6.7 cu in and might equate to about 5 horsepower, as a guess
