Some great reads in here
@JonD I think thats who I will go with too. The suzi place will do it for me.
@JustJames For me, i think there are a couple of things that are leaning more to the Suzuki, or the Japanese side of thinking. I think that their corrosion protection is a little better. I like that there is a 6 year warranty. It has lean burn so i think that my driving style will mean it is ok on fuel. After your comment, I'm now a bit worried now that I may end up being a nearly 60 y/o rev head if I also discover a heap of extra power! I like tech and the fly by wire seems to be the way to go. Its a white engine which will suit my boat a bit more. I'm pretty good with computers and what that means is that I don't have to be very good with engines and will be going with dealer servicing. There is a an American guy on youtube who see's a lot of engines and he basically said, reliability, go Japanese.
I'm happy for you and you new boat and I hope you get a lot of trouble free years out of it.
I'm going from a 90HP ETEC (145kg) and thinking that the Suzi 140 (186kg) will be the approach. Merc would be a 115 pro xs and the yamaha is a 130. I don't need to go fast and really I can only do that in Brisbane water. Offshore it hurts too much and everything gets thrown around.
Pricing, most seems fairly similar. Trying to find the year servicing pricing has been a lot more challenging
