If you are keeping fuel fresh and treating with Sta-Bil and SeaFoam ethanol doesn't matter. Any fuel older than a month pour into one of your gasoline using cars/trucks. Ethanol isn't goong to damage the motor (see below) unless you're using a motor built before the late-ish 1980s. Ethanol is actually a great cleaner. This is good for the boat's fuel system . The problem happens if there is a dirty fuel tank, fuel lines, engine fuel system. The ethanol fuel cleans that stuff up and it gets clogged in the carburetor jets. I've never had a outboard motor problem using E10.

I have been told that using ethanol free gas is best for all small motors as well.

Hi John,
Thanks for that input. I certainly like the Tohatsu 6hp weight. I also like it is designed for sailboats.
Anyone have reliability issues with the Tohatsu outboards?
Thanks,
Gerry

FWIW - Flicka displacement is 6000 lbs, M23 is 3600 (per sailboatdata.com, usually fairly close to correct). The trunk cabin, freeboard, and other layout on both - meaning the windage, or most of it - is quite similar. The Flicka LOA is actually 24 ft. but that's because of the bowsprit, hull is ~20 ft. Anyhow...Flicka is considerably heavier with similar profile, so if someone's happy with a 6hp SailPro on a Flicka that is reasonable input to consider. And, if you sail on Chelan regularly...it blows like crazy, when it blows, for sure.
And yes the Honda 8 and 9.9 are same carcass, as are the Tohatsu/Mercury 4, 5, and 6 hp. They just cripple the full HP capacity for the lower HP versions. Mostly via carburetion I assume. If you read the specs you'll also notice that the top end HP model for a given carcass is rated at a slightly higher RPM. So part of the extra HP rating is from running it faster. If you look at specs, the motors in a certain HP range will all weigh the same (or within a few lbs, for same shaft length) - all the same carcass. This holds true up into bigger HP as well, like the 35-50 hp models will all be the same carcass and so on.
Also FWIW, when I bought my M17 it came with a Tohatsu SailPro 6hp 20" shaft. Waaay overkill. But nice motor. I sold it fairly early on (to a guy with a Venture of Newport 23).
cheers, John

Hi everyone,
Thanks for the input. The 6hp seems like a good option, but I’m hesitant.
The M23 is a large boat. One of it’s weaknesses is it’s height above the water. Really high winds really impact her ability to make headway. Pointing ability also suffers because she gets pushed downwind. I even have the high thrust prop.
I’ve been in some high wind situations on Lake Chelan and have had to really crank up my 8 hp 2-stroke to make 2-3 knots. The cabin space comes at a cost and I think that is why Jerry didn’t care for the deck design. It’s good for my family of four and we love the boat. It sails great in winds up to 15 kts and only suffers beyond that.
I’ll look at the Honda engines. Interesting that 8 and 9.9 might be the same engine. If they are the same weight, why would anyone bother with the 8? I’ll look more into it.
Is Flicka an M23?
Thanks,
Gerry

Gerry,
In the case of Honda outboards, the 8 and the 9.9 are identical weights for the x-long 25" shaft. I expect they are the same engine, with the 8 simply being detuned.

Hello,
I’m not sure how many Montgomery 23 owners are using this list, but I was curious what outboards you use. I’ve been using an 8 hp 2-stroke with 25” shaft, but I can’t find an 8hp 4-stroke with the 25” shaft. Obviously, no one makes a 2-stroke any more. The 9.9 4-stroke has a 25” option but just feels too big and heavy.
Thanks,
Gerry
