Graig ,
I have ever owned 2 Stoke Yamaha's and have 2 pairs , the oldest is 25years and getting a new boat in the winter.
I know they are not the way forward and as soon as my Ship comes in will most probably be in the market as well ,
My heart is in a pair of 50HP Honda's , but if you cut thru all the BS and see Who puts their money where their mouths are my head Says Mercury .
Yamaha 4's - overpriced and the kids on the schoolbus says its not that special - 2 year warranty.
Honda - They have only ever made 4 stokes so the most experience with the technology. - More happy customers than not. - 3 year warranty
Mercury 4stroke - I have always considered Mercury "The Black Anchor" but have used some the last 2 years and must eat my words they are Awesome , value for Money and comes with -5 year warranty and a choice of Side or binnacle throttles.
I think Ultimately it will be what support there is, With a 5 year warranty at least you have a permit for 5 years to speak your mind if something does'nt work.
just as confused.
