Horsepower for your application

[snhstahl@gmail.com]

Hi Folks,
We bought a 2005 22 Cruiser last year with a tired Honda 90. Put a new 70 Yam on it and love it. Smooth, quiet, bow down where it should be without a wing/Ptrim due to less weight on transom. Boat will always be an inshore comfort cruiser. Long cruises at displacement to 15 knots are all this boat will see. Occasional WOT just cuz. Chesapeake, rivers, and ICW.

I ran a 75hp 4 cycle Yamaha on my 22’ for 17 years and loved it, there were a few times that I was wishing for a bit more horsepower but all in all was very happy with it.
Just re-powered with a 115hp 2022 Suzuki. Haven’t had a chance to even break it in yet, I’m sure I will like the fuel injection system and added Hp. Not so sure about the extra 100 pounds of weight in the stern though. Hope to get out on the Columbia sometime soon and find out.

I have twin 45s and the only time I want more power is when it is fully loaded for a long multi-day cruise. And then, it really could use about 50 more hp as all it does is burn a lot of gas and not go very fast.

snhstahl@gmail.com,
While looking at the Troy Marine site this morning, I saw you and your boat in a photo. I have seen several others discuss the 70 four stroke Yamaha, for the 22 Cruiser, but never saw any feedback on performance data. When you have the boat loaded for a cruise, including passengers, do you know what your speed is a wide open throttle?
I had a 22 for 10 years and loved it and my minimum non displacement speed was abut 12 kts. My curiosity is what margin, without WOT, does the new outboard provide above 12 its?

3 more hours of break-in, then we will see if we reach rated rpm and have the right prop. Read reports of 27-28 with 70 HP and we will never be heavily loaded. The old 90 Honda gave us 28mph (gps, reciprocal course average), but it took a long time to get there. Had lotsa hours. It liked to pause and take a rest occasionally too. Hate that unexpected silence. Dealer actually ran the boat IN the WATER for a couple hours with the new one. Pays to repower in February when they have a little time on their hands. Last boat was a Maine-built single screw diesel and after 17 years wearing ear plugs we are cruising in peace.

Redfox, a Alaskan C-Brat going way back, went from a Yamaha 115 to a Yamaha 70 on his older CD22. This is his 250 hr report. He also did a extended cruise report several years back with his boat heavily loaded, but I couldn’t find it now to share.

On our Planned SE Alaska trip coming up shortly, there will be three CD 22’s. Mikes with a 70 hp Yamaha, Jody’s with 140 Suzuki and me with twin Honda 60’s. It will be interesting to see how they compare to each other & Bill’s 23 Ranger Tug with a a 200 Yamaha.

That will be informative. I have heard the 140 is very efficient from a number of folks. On a 22, it shouldn't even be breaking a sweat. I remember when Redfox did that and I was a little surprised because he loved the 115 as well. I suspect that all the boats on your trip will have very similar fuel usage if loaded the same and captained the same. I could be very wrong though.

Pat, thanks for writing up the original C-Brat history & sharing it again here.

What amazes me is that in 2009 there were 3,600 registered C-Brats, which at the time seemed like a lot for our modest little boats. Now in 2022, there are more than 9,900 C-Brats!

HI,
I finally got the break-in hours done and ran WOT with -1/3 total fuel. 27 mph (turning speed) Filled (slightly overfilled) both tanks - 26. 13 1/2 X 10 1/2 - 6100 rpm. The shop made a good prop selection.
