Bass pro has best prices for Mercs. If you can you should wait for sale usually spring. Might have good price other times too.

How big is your inflatable? Does it have a transom, or do you use a bolt-on motor mount?

If it was me, I would take a four-stroke, if just for the sake that it's less smelly to operate. There's a Honda 2.3HP that I've been eyeing for mine.

2.3 hp and only 30 lbs......nice.

I THINK two strokes are generally lighter, have a little more zip, but then you have the hassle of separate oil reservoir or mixing. I have a four stroke 15 hp kicker on my boat. convenient, and the weight isn't really an issue on my 17.5'. My main 115 hp engine is actually a two stroke.

My 9.9 Merc 4 stroke weight 125 lbs

SamSteele · #7 08-16-2016, 10:17 AM

Weights of 2 strokes and 4 strokes are much closer now than they were in the past. I would definitely take a 4 stroke. Quieter, no mixing gas, less emissions, and weight is pretty close. Tohatsu makes most of the 9.9 motors including their own name. I think the Tohatsu is cheaper than the Merc, but they sell it as a 9.8 to avoid competing with the companies they manufacture 9.9s for.

I just put a Merc 9.9 ProKicker on my boat this spring. If I had to do it over again I would have gone with Suzuki instead as they are EFI instead of carbed. The Merc is tough to get going the first time each morning. Once it's been run once it's no problem.

4 strokes are better to be around(fume wise).

New 2 strokes arent bad though.

Tohatsu 2-stroke, 3.5 hp and only 26 lbs.
Evinrude 2-stroke, 15hp and 75lbs.

For small portable motors i like 2 strokes, they fit in a side pod on an R-44 or back seat of a bush plane.
if a 4 stroke is mounted permently on a boat, the weight is not so bad.

my boat is a seamax 320... should be 12 ft boat with aluminum floor rated 15hp.

I am thinking to buy a portable one, so the weight is definitely a big concern. And I am also thinking to go for aluminum boat when this inflatable one retires.

Who could tell me where I should go for motor in Edmonton? Thank you!

Four strokes are nice but if you are taking a motor on and off all the time for transport and storage, I would lean to a two stroke. If you tip most four strokes over the wrong way you will have a carb full of oil. Major PITA

ROA · #12 08-16-2016, 12:45 PM

Can't buy new small 2 strokes anymore, it would have to be used.

Tom Pullings · #13 08-16-2016, 01:16 PM

Older evinrude/Johnson 9.9 2 stroke. Reliable, powerful, cheap, simple, and light.

Really? 2 strokes motor not available anymore?

doyle hansen · #15 08-16-2016, 01:38 PM

I went on the journey .... that you are about to go on .... two stroke vs four stroke

My journey was for two years ... I had owned a 1993 15 hp two stroke mercury (from new) ... on a 14.5 lund rebel ss ... tiller ... after all the searching ... I went with a (next to) new 15 hp four stroke electric start ... and I am glad I did

As you know they stopped making new two strokes about three or four years ago ... however rules are not in place yet ... but it would not surprise me that in the future two stroke motors may be banned from certain lakes ... just saying

Faster, quieter, really, really fuel efficient ...

You will find the best prices on Kijji .... just set the search function for Alberta, B.C and Saskatchewan ... key words boat motor ... $1,000 to $2,500

...

I live in Red Deer and found my motor in Kamloops (almost new) 2010 for $1,500

... drove to Kamloops ... had a round of golf ... and drove back the next day ...

Based on what your post says ... 9.9 four stroke ... any brand .. should do .... decide of you need long or short leg ... electric start or pull start ....

If you would like I would not mind to find suitable motors ... I will find then then forward the emailed listings to you ... and make your own arrangements with the seller ...

cheers doyle

As far as I know the smallest 2 stroke is the 15hp evenrude etec which is actually a 30 hp and is big and heavy for a 15hp It's meant to be used as a high thrust kicker.

True.

2 strokes, of small displacement (like stuff under 10-15hp) do not pass emissions tests in Europe or California anymore and they are going the way of the dinosaur. This will soon be the case as regulators tighten up here as well.

There is no benefit to a 2 stroke anymore. They are not lighter. They are not more powerful. They generate the same 10hp, sarcastically and ironically, as a 10hp 4 stroke does. This is true of outboards.

A 10hp Honda (4 stroke) weighs 103lbs. For your set up it might be ideal.

Riverside Honda.

Buckhead · #18 08-16-2016, 05:22 PM

For use on an inflatable like that I would look for a good used Yamaha or Mercury 9.9 2 stroke. Year 2005 or newer. About 84 pounds.

You are going to be taking the outboard on and off many times so weight is an issue.

I have carried these outboards on portage many times and even they are not fun. The extra 20 lbs of a 4 stroke is a killer.

And 2 strokes generate more useable torque at lower rpm. Every stroke is a power stroke - unlike a 4 stroke.

Buckhead · #19 08-17-2016, 04:39 AM

This:

http://www.kijiji.ca/v-other-boat-wa...ationFlag=true

The ad does not say if it is a short shaft or long shaft. Short shaft (15") needed for your inflatable I would assume.

Or this:

http://www.kijiji.ca/v-powerboat-mot...-00/1144519645

Johnson is basically an Evinrude.

Recreational Power Sports in Edmonton usually has a selection of used outboards.

Sorry EZM, but a 15 hp Evinrude is only 75lbs, 25% lighter.

4-stroke idles smooth as a clock, but have to watch when you lay it down, oil can drain past rings and into carb.

Are they easy to start?

jim summit · #22 08-17-2016, 10:15 AM

The Evinrude 9.9 and 15 were built from early 70's till 2000 area. Very nice trolling motor, starts well, runs cheap.
Can idle all day at 500 rpm, or run full throttle all day at 6500 rpm.
One of the nicest small fishin motors ever built.

The mid 80's and up had better ignition systems, 95 and newer had upgraded tiller handle and shifters, but gained a few lbs.

Google "Leroys ramblings", covers alot of in depth info on these motors.

Jimbo has it right. The Johnson/Evinrude weight about 75lbs and are pretty much bullet proof. But they burn ~twice as much fuel as a equally powered 4-stroke however. Key is finding one.

Japanese 4-strokes are just as bullet proof and burn half the fuel. The weight 30lbs or more, require yearly maintenance, and care has to be considered when laying them down for transport and storage (oil will leak from the crankcase). I'd avoid the other manufactures.

Either way you can't go wrong.

AlbertaBoy92 · #25 08-17-2016, 12:48 PM

I prefer a 2 stroke for a small engine like this, yes it burns a little smelly compared to a 4 stroke, but less work overall. Not having to worry about an oil leak or checking the oil a lot. Pre mix it and you know your good to go. Last thing you want is to have a brain fart, forget to check your oil and sit like a buoy in the middle of no where haha.

AlbertaBoy92 · #26 08-17-2016, 12:49 PM

also, the last time I looked there was a little 2 stroke out board 2.5 HP on kijiji for 300 bucks! it was made in the 80's but might be worth a look!

Willowtrail · #27 08-17-2016, 03:42 PM

Evinrude E-Tec 2 stroke.
Westlock powersports and marine. Go talk to Corey or Dan

You won't regret it

LOL ..... it's not 75 pounds ............ >75 pounds Heavier.

Website says 182 lbs for the 15hp Evinrude.

Compare that to the 103 lb Honda.

http://www.evinrude.com/content/evin...ker.html#tab=0

By the way ....for a fair comparison .....the Evinrude 9.8's are like 98lbs - so 4lbs lighter - which is about the same weight really.

The older generation 15hp 2-strokes are ~75lbs. The new generation E-Tecs are huge and way heavier but I do not believe the where intended to power smaller truck toppers but rather to be kickers on larger boats.

Redneck Tommy · #30 08-17-2016, 09:01 PM

Nothing beats the old evinrude 15 hp but if your buying new the lightest option on the market right now in the 15-20 hp class is the 4 stroke Suzuki
