I have and can confirm, suzuki is better then yamaha
I've owned both and I like the technology that goes into the suzukis, having no timing belts is a massive step up. I've got a charter boat mate who got 6000 hours out of a set of 150 yamahas with original powerheads, his up to 3000 hours on his 'new' 200's. I don't think you could go wrong with either!
