Yamaha 50 2 srtoke or Honda BF50 4 stroke

Hi,

I need help deciding which engine to put on my futura mark 3.

i like the yamaha for power and low weight.

but the honda will be quiter burn cleaner and run more efficiently. but will cost me around $1000 more.

What you do think?

thanks,

Yam every day. More power to weight and sounds like a real engine.Will probably use around the same fuel at WOT anyway. $1000 buys a lot of fuel.

I'm mostly with Nos on this one, but I think I'm right in saying that the Honda 50 is about as light as 4- strokes get. To the point I could have hung one on my transom! (only rated for 110Kg)

As Nos says, at WOT it's gojg to be naff all difference in consumption. If, however you do a lot of rescue boat work (i.e sitting at idle for hours on end) then yes, the Honda will be more efficient & less smelly.

Less torque though

Yep get the Yam, can't beat the smell of 2 stroke oil.

Aye, it;s horses for courses.

If you're doing a lot of rescue, the 4- stroke will save you fuel ,will make the idling ambience a lot less, fumey & noisy, and if you're doing a lot of stop - start, chances are you'll have a lower pitch prop which will counteract the torque issue.

I just try to shed light on both sides of the argument, but you'll notice I have a premix 5800rpm lump on the back of mine!
