Yeah, we’re on the same page. I have a 2hp as well. Honda, old! Works great. No gear box, swivels 180. What is your tow vehicle? Sent from my iPhone

Each place has call for different needs. I sail frequently on SF Bay and I time my departures with the tides. Swimming upstream is never recommended. I sometimes stow my 27# motor under the cockpit sole to lower the center of gravity. The small motor is easily stowed while under way. When moored it is put away, out of sight, out of mind.
I appreciate the lively conversation on all topics here.
I think this thread began with the strength of the M17 transom to withstand loads imparted by motor mounts and ladders. Does a cantilever effect caused by a motor offset 1ft aft add extra leverage to this equation? I know every M boat does not have a notch so moot point in many instances.
The 2hp swivels 360 and gives full power in reverse. I can "park" my boat with great confidence and not worry about shift linkage. Air cooled means no impeller service or sucking crud into the "cooling system". I fire it up in the garage before each trailered outing so I am reasonably sure it will work when I get to the ramp.
The whole covid sailing season saw me launch 9 times; each time I refined my launch procedure and refined my gear/supply list. On my first outing this year I felt for the first time that I had nearly everything in its place, and left most of the things I did not need at home.
Your boat has to work for you!
Thanks again for the lively conversation!

Hi all: I worry about the currents in the San Juan’s and the need for the 4 horse. But I will investigate getting smaller motor Pete

I launch many times in a season and not having to deal with the motor each time saves me a lot of trouble.

I also like no fuel tank in the cockpit. Nothing underfoot.
On a sail in the delta there was much water hyacinth tangling up on motors. Because my motor is mounted directly to to transom, the prop is closer and within reach to clear of obstructions.

On my M23 there are definitely places in the San Juan Islands where I can barely make 0.2 kts head way against the current with a Honda 9.9 at full throttle (and other places where I would never even attempt to go against the current). Obviously there is a large difference between boats here, but a 2 hp motor on an M17 or even an M15 would probably have a similarly difficult time. Usually one can plan a course to coincide with the currents but occasionally you have the dilemma of choosing which location you will have to buck the current (or choose an alternate destination).
My 2¢ only. Others with M17 or M15 experience in the Islands may have better information.

IMO 4HP motor is a great size for a cruising M17s. A 3.5-HP will work just as well.
A 2/2.3/2.5 is fine for 70% of what one will experience.
Anything bigger than 4HP is just more that doesn't help ... especially with current. The displacement hull design means you hit max speed and then done. More horses doesn't help.
HP can assist in wind and to a less extent waves.
The problem now is there are no new build true 4HP motors. All are repowered 6HP blocks - so heavy! The old Yamaha 4HP was a true 4HP block. It has been discontinued for years.
A long, 20", shaft motor is needed on all Jerry's 15 & 17 designs, the 15" standard shaft motors will cavitate easily in a slight chop.

My understanding is that Hull Speed dictates maximum speed with respect to water, no matter engine size on a displacement hull (but if anyone gets an M boat up on a plane please post a video on YouTube, I want to see that!).
It doesn't matter how big a motor you have on the back of your Montgomery, it isn't going to go faster (with respect to ground) than hull speed against a current. For the M15 that is about 4.87 knots ( http://www.msog.org/specs/race_ratings.cfm), if the current is 4.8 knots or better you aren't going that direction!
Now, if the wind is blowing against you, that's a whole different question, but with any luck, the sails will be able to help :)
