Should I Buy the 2009 Yamaha 9.9 2 Stroke or 4 Stroke ?

Looking for opinions. I have my purchase narrowed down to this. There's only a few hundred dollars difference between these 2 options so no biggie. I plan on having this motor for as long as it will last me.

I like the idea of a quieter engine and better gas consumption but it would mean lugging it around would be tougher (it's about 95 lbs whereas the 2 stroke is about 80 lbs)and would it be harder to maintain ? :?

I'm having trouble finding reviews on the 2 stroke. I read one review from one guy that owned a 4 stroke..he complained that it would never work right until they put an electronic fuel injection on those smaller motors.

I really don't know...what do you think ? :?

Sorry about that :oops:

It would be used interchangably on 14-16 ft aluminum boats. I'd need a short shaft. I need something under 100lbs because I'll be moving it around (these boats don't have trailers).

The only down side to a 4 stroke is the extra weight, but just the fact that it is quieter and no smoke is worth it.

I got a 4 stroke yes it is nice and quiet and no oil to mess with the weight I,am not sure haven,t had to take it off yet.I won it with the boat and trailer first time with a 4 we alway,s had 2 stroke.

(My opinion), without a doubt, go with the 4 stroke!!! As far as I'm concerned, the weight thing is the 2 stroke marketing people's attempt to discredit the 4 stroke. I have a 4 stroke (20 hp on a 14' boat). I would suggest the 9.9 might be a bit small (but now we are getting into personal preference and need). I fish with a guy that has a 16' with a 2 stroke on the back. What a smoking mess that is!!! I get sick just fishing near him (never mind being in the boat). Great on gas, reliable, quite, easy to maintain ... 4 stroke man!!! You'll be happy you did.

Trust me. Go with a Briggs and Stratton.

And good earplugs with the B&S :)

4stroke in my opinion ( pref 15hp)

How old and solid are these boats? Small 4 strokes (2 cylinder models), while they are quiet and fuel efficient and clean burning, put out a vibration or pulse that will excite every rattle on an old boat. I had an old boat (14' aluminum) with a 2 smoke 9.9. It was fine and the two worked well together. I bought a new 15 hp Suzuki 4 stroke and the boat rattled so much that I gave up on the combination and bought a newer hull for the 15. A friend who has a Honda 15 4 stroke noticed the same thing on his zodiac type boat. He says the new motor makes the boat hum.

Just something to think about... The larger 4 strokes (with more cylinders) do not have the same vibration/pulse issues. Of course if you are hoping to replace your boats some time soon, the old boat complaining about the new motor will help to speed that along.

for that small of a price difference, I don't think it's a contest, 4 for sure. No smoke, better for the environment, no mixing etc. etc. I would not be surprised if in the next several years many small lakes ban 2 strokes, there is chatter in BC of a provincial ban in the future and others may follow their lead.

Well I will step up and defend my Yamaha 2 stroke. For one it is oil injected, no mixing oil and gas. It is quiet enough. And it really doesn't throw off that much smoke. I know there are a lot more negatives than positives when comparing a 2 stroke to a 4 stroke, but I have to say, it has been an excellent motor for me.
If weight is an issue, you might want to do a comparison.

They will never ban 2 strokes or old antique motors, it is just hype, actually todays 2strokes are burning cleaner than 4strokes. Check out the Evinrude E-Tech motors and you will see.
Todays 4strokes I find are not that durable, especially the smaller ones, they tend to need more service and definately have vibration and motor mount problems
I think the lifespan of a 70's or 80's johnson 9.9 would quadruple or better the lifespan of a new johnson 4stroke 9.9 and with virtually no maintenance costs
Actually if cost was not an issue for a 9.9 I would still buy the 80's Johnny 2stroke
