Re: Evinrude outboar Short shaft vs Long shaft [links]
If your transom measures 15 inches you need a short shaft mtr. Putting a long shaft on it you'll get a lot of spray and no performance.
As of right now, I have a 6hp( what im assuming is a long shaft) motor. I'm looking to upgrade to a 15 horse but not sure what to get. From where my motor mounts to the transom to the bottom of the prop is 28" Is that how to measure for shaft lengths or is it to just above where the prop starts? more

Finally, consider the Torquedo electric outboards. Not cheap, but they are supposed to be good sailboat pushers and shaft length is adjustable on some models I think. here
I too have a DS II, a short-shaft will "work" if clamped directly to the transom as O'DAY intended, although you will need to shim it a bit to get a better angle for the mounting. I started out using a short-shaft outboard (2.3 hp JOHNSON) and as I say it will work. but is not ideal! O'DAY recommends a long-shaft and before buying my DS II I really doubted the need for the long-shaft. I now have a 2001 4HP Johnson with a long-shaft, it was worth the slight extra cost!! I would definitely go with a long-shaft (20") on the DS II especially if I might keep the outboard to use on my next (most likely bigger boat). I no longer have trouble with the prop coming out of hte water in waves, and can move around the boat with out risking the prop coming out of the water. I'l linclude a picture of my boat and motor, I did end up adding a plywood motorboard, bolted to the transom to try to better angle the outboard. I don't like the look of a bracket, especially those adjustable ones that lift the outboard, they look out of place on a low-freeboard boat like the DS II. A fixed bracket is OK, but I prefer what I have. here
As for size, on the DS II I wouldn't go with anything bigger than 4-5 hp, unless you intend to get that bigger boat after only a year or two with the DS II, 4HP is plenty of power (could go with smaller, but the 4 provides a great reserve of oomph!) A 2-3 hp will be about right. but then may be too small for your next boat. Over 4hp tends to get heavy as well, the Honda 5 is not too heavy, but is still more than the 38# of my 4hp Johnson. Unfortunately, the newer 4-strokes are not lightweights, but the Mercury/Tohatsu/Nissan/Johnson 3.5 hp is not bad, I think it weighs about the same as my 4hp Johnson. Not sure if it offers the option of a remote tank, but that is a good feature. especially once you move up to a bigger boat where you may be using the motor more and will appreciate not having to hang out over the transom to refuel the built-in tank on the outboard.

PS: I added an afterdeck to my DS II, so. that is why in the pictures she may look more like a DS I. Unfortunately, I don't have any pics showing the old short-shaft outboard up close while hauled out. here
150 HP (2013) Mercury Fourstroke with 15x15P SS Enertia (Thanks Todd!) - 41 MPH at 5800 RPM, light load. 39 MPH at 5700 RPM, heavy load. Love this motor.
Maybe my real question is do the new 150s come in both sizes? If they don't, then I don't really need to know since there won't be a choice. What I have now would be irrelevant in that case, as they are gonna get my trade-in regardless of what it is.
24-SSL (2012) Express w/6 strakes, awesome cable steering because I'm cheap, big gouge in pontoon where marina staff sideswiped their dumpster, redneck emergency toilet via bucket with a toilet seat glued to it (hey, its just a toilet), polished toons and a broken ladder strap. Hoping to log my 200th trip out this year (2018).
Sorry for pressing hard on this, just hoping someone chimes in before I make a deal on the wrong motor size tomorrow! It might have been quicker for me to have just taken the hour round trip down to the boat and back to measure it like Jim suggested at the top of the thread. Maybe I'll run down there early in the morning before work and take some measurements, then call the dealer and make sure he has the right one for me.
Is the rule that the shaft length should match the transom height? more
