I have the Mercury 115hp EFI 4-stroke, only because that's what came with the boat when I bought it used. (2007 CD-22). From what I've seen running with others at the two gatherings I attended, if the 90 HP is 100 lbs lighter, I would opt for that given a choice. While I seem to be the fastest boat in a race, we are only talking a few MPH, and at that top speed the boat is kind of squirrely anyhow. Perhaps if I was towing having the larger HP would make a difference. But having the biggest motor allowed isn't always the most efficient. Especially if it's drinking a bit more fuel too. Colby

My 04 22' is limited to 100hp. A single 90 would save me about 50 lbs compared to twin 50's. But then I would lose the redundancy I find important when cruising Bay of Maine

those twin 50 sues look great.

Most of us with a big single have a kicker (for redundancy) and end up the same or more than you will be. Me 386 plus 57 pounds.

On the 25 you would usually be heavier with twins.

If i were repowering with twins, I like the 50 sues

Colby: only the 115 Honda (Tohatsu 4 stroke) is that much heavier than the 90.

interesting comment Dr Bob,

what is your thinking wanting a 115 engine (honda) at 500 lbs. vs a 400 lb. Yamaha ( 2200 cc vs 1750 cc. )? not concerned about the weight on a 22?

curious...


I have not looked at the Yamaha 115 for the C Dory. I had a Yamaha 115 on a Century 18 foot CC and have a Suzuki 140 on my Caracal 18. (The Suzuki 115/140 is 2044 c c, and 410 lbs.) Both were/are very good engines.

The Honda is 1496 cc vs the 2200 cu in for the Tahotsu (Honda). The reason I might consider the Tohatsu, is if the Honda gauges and controls could be used. I would prefer the Suzuki for several reasons.

As for weight--not a huge issue--I could move two of my batteries forward and get 140 lbs out of the stern--I run heavy most of the time anyway. My kicker is only 30 lbs.

However, a good point, and I probably would have to compare the various options, if I was really going to swap out a 330 hour carbed engine for an injected one...

I'm planning on repowering this winter so this subject is pertinent to me. Weight has always been important to us - have run the orignal 70 HP Johnson (2 stroke)for 19 years which has been a great motor. Only complaint is being underpowered if fully loaded. I want mid range torque/power - not top speed. We will always cruise at 14-18 knots no matter what motor. We want to be able to maintain that easily when loaded against strong currents etc. We are currently looking at the Honda 100 HP (366#s) and the Yamaha 115 (377#s). If you factor in a new 8 HR kicker the weight is about the SAME! The Honda 115 HP is > 100# heavyer which is just too much. I'm a Honda fan but a Yamaha is a close second and for the same weight this is really a difficult choice. Any thoughts from anybody.

I would look at the Yamaha line. They make a nice light F70 hp four stroke that if propped right it should do the job. If you want to burn more cash and fuel the Yamaha F90 or F115 hp would be dependable choices. A lot depends how close you are to a dealer if you need to seek professional help. Yamaha has lots of dealer locations. We always bought service parts for our Yamaha's online from Sim Yamaha who offer decent prices good advice and dependable service. www.simyamaha.com

And if you are going into Canada, Yamaha has a much better service and parts availability than Honda, for sure and probably than Merc also. Not sure on the Tahatsu or Suzuki's but, I remember sitting on the dock in Telegraph Cove with George and Carolyn (KerriOn) and we noticed that number of Yami's around us. Probably 20 or 30 of them to any 1 of something else. There must be a reason for that.

I did notice at one time at a C-Brat Get Together that in one place there was a propensity of Honda's, Not sure if the mix has swung or if it was geographically skewed.

I know my boat came with Yami's. It was set up buy a guy who had had 33 other boats in his life time, and he was getting ready to fish his way to Alaska and back. He had to know something. I like that it starts always, every time, first crank, and runs when I want it to.

I think I remember reading that many of the C-Brat dealers (or the builder?) had some arrangement with Honda for good financing packages. That would account for the great number of Hondas on them. OTOH, from watching the site, I can see that just about every C-Dory sold by Three Rivers Marine in Florida was Yamaha powered - so I guess that dealer had its own reasons for going Yamaha.

I think everyone agrees that all 5 manufactures put out a pretty good motor. (Honda, Yam, Merc, Suzuki, Tahatsu). And yes, Mercs 115HP seems to be the lightest (159#) plus merc is also making it smaller in outside measurements which is good. I am suprized there is not more interest in the new Honda 100 HP (which I assume will take the place of the Honda 90 HP - same block etc). This seems like it could be a pretty good motor for a Cdory 22. I was speaking with a Canadian the other day and he said there is by far more service for Yamaha and Honda up there ( although it seems like Les Lampoon said Honda US warranty does not cross the boarder ??? is that possible - I might have got that wrong). When the 115 HPs get close to equal wt with the 90s then they get tempting - again for mid range power when loaded on Puget Sound (not for top end). If strong current and aggressive water were not an issue then I probably would not be thinking of a 115 HP. Also, the power is there but you don't have to use it plus the mileage I'm told is about the same (maybe close to twice what I get with my Johnson 70 2 stroke ?).

I may have this wrong, but it's been my understanding (a guess) that the national importer of the motor governs the warranty in the nation served.

This means that "Honda Marine Group, USA" controls the warranty issues in the U.S., and not the Honda manufacturer in Japan, at least directly.

Of course, they (U.S. Distributor) have to work in cooperation with the manufacturer in Japan, but the policies in the U.S. and Canada (with its own distributor) could be different.

Looking at it globally, there would be no way Honda in Japan could address all the world wide warranty issues in each country, and thus they'd make the distributor in each country responsible for managing heir own balliwick, which might be very different in the USA compared to, say, Indonesia, South Africa, or the Belarus.

Oh, and by the way, this is why if you bought a Honda from a dealer in Mexico to save money, the U. S. dealerships won't honor the motor with their warranty, since you didn't by it through their network: manufacturer/importer/distributor/dealer, etc.

I repowered from a 2007 Suzuki DF90 which was infected with the exhaust manifold issue to a 2014 Yamaha F115. Wonderful engine. The extra few horses are notable coming out of the hole and the little bit of extra midrange torque is also helpful holding it on plane at low speeds. I tend to run my 22' Classic pretty heavy - inflatable, extra gear often extra fuel, doesn't seem to bother it. It was also noticeably quieter than the Suzuki which is a wonderful thing.

"COLD WET DOG" thanks for the info. Is your Yam 115 the new generation (377#)? How is your MPG compared to the Suzuki 90? Is there a large or small difference in power between the 90 and 115 hp. Do you need trim tabs to keep the bow trimmed down or does it trim ok with just motor trim? Also how much fuel do you carry (what tanks do you have?). What kicker do you have? Sorry for all the questions but this is really helpful to me. Tommy J.
