I had a 225 on our last rib but we have a 250 now its two years old and never missed beat, As for the weight
the whole question is up for debit, Its do you want flat out speed where money is no object for fuel, strap the kids etc.
the way i see it, if you have a Merc 300XS Etec 300 fully laden with fuel and four up
and i have half a tank and two up,
Just how much quicker would you be in a slight to moderate sea state
I went with Yamaha because my last four engines have been Yamaha,and i feel confident with them, but thats not to say Suzuki, Mercury Evenrude are not just as good, and in other ways better, the thing that would swing it for me is the free extra warranty and lets face it 0% money cant be bad
