Re: Engine comparison ?
Based on historical evidence of Yamaha's ability to produce a R-E-L-I-A-B-L-E series of 4-stroke engines up to and including the F115. Mercury's design has no track record at all...That doesn't mean that the Mercury is bad. It just means that between the two the Yamaha is a safer bet. A performance comparison between the two is not particularly important to me as I'm sure each engine, at one RPM or another, exceeds the other in useable hp. Since I loathe all 4-strokes I have no bias between the two brands as I wish a pox on both. And the Mercury, in the long term, may prove to be equal to or superior to the F115. But as of today I wouldn't want the Mercury on the back of my boat. I would take one if it was free...But, then I would sell it to someone else and put a nice DFI outboard on.
