I have a 250 HO G2 on a Basscat Puma, in one year I just used 2 gallons of oil, it sips gas, has a 10 year warranty which seems to provide the best coverage of all. It is quiet and really Hauls Bass, I got over the odd look after a couple weeks and now think it looks bad [censored].
I'm still considering, I love my yamaha and how quiet it is at WOT. I'm in the market for a new boat and trying to decide....thanks for the info.
