yea they are good engines just like any other engine but only if you treat them good and with plenty of tlc! other than that their not a mercury but if its in your budget its a good motor
They make great kickers. I've got an 8hp on my 20ft. Trophy and my father-in-law has a 9.9hp on his 25footer. Reliable and trouble free, but they can't be ignored - regular maintenance is a must.
