Horsepower size

I would recommend you have trim tabs if you are considering the 115. Without them my boat with a 115 Suzuki will porpoise big time at high speeds.
I love the engine, but I really dont like all that weight on the transom. I also have a house battery by the bilge pump, and with full fuel she sits low in the water. I keep having to increase my bottom paint above the factory paint line. Currently about 4 inches above it. ( I keep the boat in the water)
 
Thank you all for the imput. I'm looking at Suzuki 115, Yamaha 115, and now a new player,E-Tec 115. Like Suzuki, but the closest dealer is 350 miles, and we all know "Murphy's Rule". E-Tec and Yamaha dealer is 60 miles away-and no mountain passes. This is worse than buying a new car!
C-Dory sent me a new sticker for the helm, go figure.
Will post my experience after the 2008 salon season.

You could always buy a Johnson. It's the same engine as the Suzuki but the opposite color.

Or a Mercury, which is a black Yamaha! (Actually a Yamaha powerhead on a Mercury lower end unit, if things haven't changed.)

Joe - I haven't been on the C-Brat site for quite a while, but am getting back in the groove. Saw your mail about the Yamaha 115 not getting your insurance company's approval. Interesting. When I repowered to my 115 Merc. EFI (2006) which had the Yamaha power head, my insurance agent said no problem. Correct me if I'm mistaken, but aren't both the Yamaha and Mercury 90HP and 115 HP motors essentially the same other than fuel adjustments., that is the same weight, configuration, bore stroke, etc.? I went to the 115 EFI because (1) I boat at high elevations and (2) at that time (2006) Honda 90 didn't come with EFI. My 1996 Honda 90 was a wonderful motor (the Merc 115 EFI is loulder), but unless I could rely upon consistent fuels, which was difficult when traveling around the country, keeping those four carbs clean was a big challenge. One story about how quiet the Honda 90 can be, I pulled up to the fuel dock at Bridge Bay Marina on Yellowstone Lake in the summer of 1997 and forgot to turn off the engine. The attendant was putting in gas in one of the side tanks and remarked about the stream of water coming out of the pea hole. Neither he nor I could hear the engine running standing so close by. No exaggeration! Helps to be partially deaf, I guess, but hardly a safe practice. From what I have seen of the Yamaha EFIs they are dandies.

Yellowtone-

It's great to have you back, John! Hope everything is going well for you in the middle of this long winter.

Actually, my insurance company never got involved, we never got that far!

The dealer who I had selected to buy a new motor from (Gunther's in Sebastapol, Ca.), was the one who said they wouldn't sell or install the motor on my CD-22 because of the liability issues. I wasn't adamant about wanting the 115 anyway, so I just let it go and settled for the 90.

The motor has been flawless, so I've never regretted the decision. It's so quiet at idle, we sometimes try to start a running motor!

Yes, the Yamaha and Mercury 75, 90, and 115 are, for the most part, the same engine, but with these differences:

The 115 has increased displacement, from 1596 cc to 1741 cc, and the pistons, rods, cylinder sleeves, and some other internal parts are "hardened" to take the extra strain. Of course, the fuel and ignition systems are raised up to a higher level as well. The hardened parts make it more difficult to break in the engine and seat the rings, so some folks have had their motors "make oil" as gas slips by the unseated rings in early use. They have to be told to go out and run the motor hard for awhile to finish the break in period.

Cheers!

After running my 115 Yamaha on Coop's Cruiser for while now. I feel I made a great move up-powering. You don't have to run WOT to produce a decent time saving cruising speed. :idea I turn about 4600 rpm to produce around 26 mph, that's loaded with three adults 50 of fuel and all the other supplies. Fuel economy appears to me to be greater than when I had the 90 honda. Plus if I add people or other crap to the boat I have plenty of power to do what I need. I run a 4 blade solas 15 pitch that gives me the best overall performance. WOT is 5800 top speed around 35 mph :lol:

If & When the J.M.R.II needs a repower it will be a 115 Yamaha :wink: :mrgreen: :beer
 
I exchanged my Honda for a 115 E-tec, this is on a 22' angler which is heavy with gear and crew. I ran it at sea level and had the factory reccommended 19 pitch prop. At WOT it turned 5100 RPM's with a top speed of 35 mph. I have trim tabs and a paratrim (sp). Running at 29mph was fine, but above that you had to trim the boat out or it wanted to get squirrely in the rear. Get it trimmed out a it was fine. Fuel consumption was about the same a the 90, will get a better idea when I start fishing in July. Will switch to a 17 pitch and see if I can get the factory reccommended 5500 rpm's. Do I like it, you bet. Thank you, Cooper's Coop, hope to see you on the island.

Good choice. Before I bought my Angler last year, Les (EQ harbor service) had it rigged with a 115 E-Tec for his/Dusty's personal use. I chose to change power for my use, but I assume the 115 E-Tec was appropriate since Les was a highly credible C-Dory dealer at the time (still highly credible, no longer a C-Dory dealer) and doesn't strike me as one who pushes the envelope on safety/sea worthiness. Keep us posted. Mike.
