Would You Ever Repower a 22' With a 60 Horse Outboard ?

I have two Honda 40s. Running one motor, maimum speed is 17 mph, comfortable cruising 12 mph.

I might look at a C22 with an 80 hp Yamaha. Does anyone have one like this? What can I expect with a medium load vs. a 90hp?. And, if it has digital gauges, can I get an hour readout? The owner doesn't seem to know. Thanks.

Honda did prop tests on various 22 Cruisers over the years. I've posted a link to these tests before. Here's a link to their prop test main page.

Here's a link for a BF50.

Here's a link for a BF75.

Here's a link for a BF90.

I suspect a 60 would be somewhere between the 50 and the 75, but that's a pretty wide range. The difference between the 75 and the 90 doesn't seem so great.

Have fun!

Harryr,
I have a 115 Yahama 4 stroke 2003 engine on a different boat than a C Dory. The digital guages show the engine hours on that engine.

I think that the 80 on a C Dory would perform up to the boats' performance. These boats are not meant to be fast boats (I found that on my 22 anything over 30 MPH was a little skiddish)--and I would expect that in a medium load with the correct prop you would hit the high 20's to 30 mph. Yahama engines have a good reputation.

As previously said, I think you would be sacrificing safety, fuel mileage, and resale value by going that small. I repowered with a 90 Suzuki a couple years ago and have discovered the joys of displacement cruising; I literally enjoy myself more and get great fuel mileage which allows me on a limited budget to stay very active in boating. I also run pretty heavy so I feel the need for the extra power.

I have many friends who are trying to sell their boats or who just keep their boats idle due to the fuel costs, thankfully, we have boats that still allow us to enjoy being on the water.

Yamaha, Suzuki, Honda and Evinrude all make very good motors. I dont include E-Tec only because of some cold weather issues up here but we are lucky to have such reliable motors. I had a Mariner once about 20 years ago when I lived in NC and have to say I was not so blessed.

I could not plane my CAPTAIN'S CHOICE on one of the two 45's. I think it had to do with weight.

Wayne McCown · Posted: Thu Mar 06, 2008 1:43 pm Post subject:

Weight (at the back) is definitely a factor re planing. Although I prefer twin engines, a single engine of the same HP typically weighs less (and the newer ones are lighter than the older ones).

The key variable for most of us is the amount of gas we have in the tanks. Gas weighs ca. 8#/gal. Thus, 40 gals. weigh ca. 320#, whereas 15 gals. weigh ca. 120#. That 200# difference (at the back) will effect planing speed!

A further note: I have found that Permatrims (see discussions elsewhere on this site) are particularly helpful on the low end, getting the hull up on plane and holding it there at a lower speed.

Harry,

I've got a 2000 yami 80 on a 22 cruiser. I would recommend the engine. Never had a bit of trouble with mine. I am the fourth owner. It would run similar to the Honda carbed 90. The new fuel injected models perform much better.

The yamaha is a good engine. The 80 is the detuned 100 h.p. Had I bought the boat new I would have got the 100 version. When/if I repower it would be a 115 h.p. The C dory can carry a ton of weight. 30 mph top speed is fine. I would just like the boat to cruise/perform when it is heavy like it does when it is bare bones empty. The kicker pushes the boat at hull speed quite well and whisper quiet and efficient, allowing operation from the cockpit.

With the 80 h.p. version you only get 80 h.p. and that is rated at 6000 rpm. You have the bigger cowling/engine and weight of the 100 always with you. We always overnight, so lots of camping stuff, two big dogs and a 15 H.P. kicker. Always loaded way heavy. Even for a weekend, my wife carries atleast a weeks worth of canned stuff just in case... I am over propped with the 15 pitch and will try a 14 pitch to get the rpm's as close to 6000 as I can when loaded.

On the Hour meter: My boat has analog gauges but has a separate digital yamaha hour meter mounted in the dash. A meter could be mounted anywhere between the engine and the helm. But I would think the owner would be aware of that. I am pretty sure that there is no electronic brain that would store engine hrs. on a 2000 model for retrieval. Like others have said for most people 100 hrs a year is a lot. We often cruise out away from the crowd, anchor on some remote beach and camp all weekend. Even if the boat was the last one you owned. With proper maintenance you would have a tough time actually wearing the engine out. Thats why I may never get to repower...

Pete,

I've been looking at both, Yamaha & Mercury and I'm pretty sure I'll go with the Mercury Big-Foot. I believe Mercury will offer more options with regards to available prop pitch. I'm in Las Vegas right now and I've already seen some four dollar a gallon gasoline.

Next week I'll be in Sacramento, CA and I'll talk to the boat dealer, that I've done business with in the past and get his opinion. I don't have a need for speed at four dollars a gallon! Shocked

There is no way out for me. My want for a lighter 60 hp has met with failure. Like it or not, it looks like my repower will be a Yamaha 90 hp four stroke. Almost 100 lbs more than the previous 90 hp two stroke.

If you are talking about a single Yamaha 80hp 4stroke I belive that that engine just comes as a jet pump not a prop. It is a 90 hp minus 10% for the power lost at the pump. A couple of years back they made it so the stated hp is at the prop/pump and not the crank shaft. Anyway a couple of weeks ago I was skimming through a Yamaha broucher and I belive that is what I read concerning the 80hp

Thanks Joe,

Just happened to see your boat parked next to the cabin at Eagle Lake last October. I was on a quick fishing trip with a friend of mine. He gave me bad instructions as to where he was staying and I was running a little late, but recognized the C-Dory.

Hopefully, I might bring my boat to Eagle Lake later in the year.

Bill- Too bad we're talking about a 350-400 lb outboard, otherwise I'd take my motor off my transom and loan it to you for a few weeks to try out! Good idea for motors of 15 or less HP, though.

I've got a cabin at Eagle Lake called the "Fly Rod Inn" rented for a week at the end of October during the dark of the moon.

Best trout lake in California, and my favorite escape from Shasta Lake!

Cheers! (and tight lines!)

Joe. Teeth
