Yamaha, 4 stroke motors

[Jim Rose]

Getting close to decision time for a 22 ft CD. What motor, 75 or 90hp? ( with, lets say, 4 adults on board and fuel) All views gratfully recieved but please be nice - I'm new. Jim

PROBABLY A 90 IF YOU WANNA GO FAST...

I am unhappy with my boats power. I would like it to run when heavily loaded like it does when it is empty. SOOoooo....Get a 90 H.P. EFI. You can get 75 H.P. from a 90 H.P. engine at a lower RPM without having to run wide open. With the 75 your only getting about 60 H.P. at cruise.

Usually more economical and less wear/strain on the more powerful engine running lower rpm's. If you need the extra power, with the 90 it is available. The 75 is usually a detuned 90 so the engine/weight is the same. That puts you at a disadvantage just in the engine. Less power with the 75 VS. 90 only moving the same engine weight. Yea the CD was originally made for a 2 stroke 75. But a four stroke 75 usually weighs about 100 pounds more. So it takes more power just to move the extra weight of the 4 stroke engine. Now add the boat weight and all the gear that a CD can carry and performance only goes on down.

My boat came with an 80 H.P. which is a detuned 100 H.P. I carry lots of camping stuff. When the boat gets moving good and smooth it's close to the upper limit in RPM's. No engine is economical at full power. Not a day goes by that I don't wish it had at least 100 H.P. engine. (It does it just puts out 80 H.P.) A 115 would be about perfect. Nothing worse than an underpowered boat.

If you only cruise with a few people and keep the boat light a 75 may be ok. But if your not satisfied it is a costly upgrade. Resale is generally better and easier with the largest recommended horsepower engine. You may want to ski, have kids or grandkids that would like to be towed on some water toys. I know the CD isn't the best ski boat but with a little H.P. and smooth water you can just have more fun. Makes the boat that much more versatile.

Check out the Evenrude E-TEC for 2 stroke lightweight cutting edge technology and 90 H.P. The best of both worlds. Made in America, too.

C'mon out Don. Not sure what you tow with but my Dodge has a 488CI V-10 in it. That sucker will pass anything but a gas station
And that's not good with gas here at $3.10 a gallon. At least it burns regular.

You guys got some rough water if it has a 6% grade in it...Must be a left coast thing.

As for Red Fox.... I think he's just jealous... I dearly love his pictures though, they are great!!

In reviewing Tyboo Mike's poll on outboard choices earlier this year...

Evinrude 9% [ 13 ]
Honda 52% [ 72 ]
Johnson 5% [ 7 ]
Mercury 2% [ 4 ]
Suzuki 9% [ 13 ]
Yamaha 19% [ 26 ]
Other 0% [ 1 ] BTW, what else is there? Tohatsubishi?


Total Votes : 136

And, if I recall, 26 of 30 boats at the Eastern Shore Gathering had Honda power, there must be a reason, something besides good press? I'd still buy a Yammi if the deal was good though, as I said in an earlier post, the real key isn't the decal on the hood, it's whether it starts when you turn the key, it gets you out and back and it doesn't cost too much to maintain... Each to his/her own! I do like those EFI engines, mine look too much like the motorcycle engine on my son-in-law's HOG.

Still like the Fox's pix!

You guys asked for it .My truck is a Cummins , never needed juice box. A real mans truck has 6spd, packs 4000pds sliding camper + pulls the C-Dory all of that on about 12.5 to 13 mpg. Not bad for big 6 real block diesel. If I would want to go real fast I would buy my self a HEMI. Juice Boxes are made so the Cheby & Ferby can beat those small 6 block DODGE up 6% grade, without those set on 3 or 4 or,,, you would not beat a loaded Dodge up those big hills. Gary SEA RAM

Best answer so far: Chris/C-Weed. Well stated. I'm extremely happy with my 2005 Yamaha 90 EFI engine. Runs just like a new car. Totally renewed the boat, performance-wise. Glad I bought the 90 for the reasons Chris stated.

The rumor is that Honda will add EFI and redesign the accessory systems and lighten the overall engine for either 2006 or 2007 for their 75 and 90.

We'll know real soon if it's 2006, because the boat shows are about to start. Wouldn't want to buy a new engine the year before it was finally updated.

If you don't want to wait on Honda, just buy the Yamaha, they have today what Honda wants for tomorrow. Joe.

On the way back to Louisiana from Seattle, after we picked up our c-22, we got a solid 14 - 15 mpg the whole way. The only time I had to down shift to 5th gear was climbing a pass east bound between Washington state and Idaho. The truck only had our gear (equivalent in weight of one person), and the two of us in it. The boat was full of fuel and water.

My truck is a 2002 Dodge Ram 1 ton dually with a 6 speed with 78,000 on it.

I run all synthetic lubricants, and only burned 1/2 qt of oil round trip.

I have a 75f and can't be happier with it. In my opinion it has more than enough power. I use it for water skiing, fishing, and have hauled lots of people and camping gear. Always gets up on step in a heartbeat. I saved 1000.00 over the 90f and have no regrets. Make sure you get the right prop.

90 -- starts, stops, and does it when you want it to . . .
