I find this an outstanding outboard
. We took an anxiety-filled plunge and bought one when it first came out, hoping to not be a pioneer with arrows in our backs. All anxiety is gone now. It out-performs our previous Honda
, and every 2-stroke made - while weighing less than our Honda
, and about the same as every 2-stroke in its size.
I can't emphasize enough what a difference a computer-controlled direct injection system makes. The fuel injection is constantly being optimized - hit the throttle and the response is immediate; keep a constant throttle and the system goes into a lean burn mode that just sips the fuel.
That last bit took me awhile to realize. I noticed that I was rarely putting fuel in the tank compared to our Honda (which was no slouch in the fuel efficiency department). But our normal mode of use is to jump it up on plane and keep a constant throttle to keep it there - where the lean burn algorithm kicks in.
Compared to all our friends with 2-strokes, I would say we easily use 50-60% less fuel than they do. Our Honda used ~40% less fuel than their 2-strokes, so I would say the Suzuki is ~20% more fuel efficient than our Honda. Keep in mind, though, that our Honda was a 15hp, while our Suzuki is a 20hp. The fuel efficiency difference could be more like 25-30%.
The downside is that I have unintentionally ran it out of fuel because it is so long between tank fills that I simply forget to look at the tank level. We use the dinghy
a LOT, and it is still a forgetfully long time between fills of that 3gal tank…
Then there is the blissfully quiet and smooth operation of a 4-stroke. We hear our 2-stroke friends coming from the time they start their OB's, and understand that there will be no conversation in their dinghies when underway. A funny
story is that ours is so quiet at idle (and other speeds, but that isn't relevant to this story), we dinghied over to some friends, jumped on board for cocktails, sat in the cockpit
with the dinghy
literally 6' away from us and never noticed we forgot to shut it off. For the whole 4hrs we were on board...
Now, everyone will go on about computer control and fuel injection, and how they want to be able to fix their engine
on a beach with a rock and some seaweed. Let them have their fun. We have had zero issues with ours, while several of our cruising associates with similar aged Enduros and Tohatsus have been working on theirs regularly. Constant carburetor problems, along with other issues not applicable to us.
To be fair though, we have an external fuel filter/water separator on ours. No matter how many times I stress this point, people still decide to run their OB's without one of these. I bet that if these were fitted to all OB's, then 99.9% of all problems would disappear. I know this has been the case for us.
Well, that is our experience.
