Measuring the shaft of an outboard

[Bobby Stone]

If I have to buy a new outboard for my oday 23, How do I measure the shaft of my outboard, so I know what to get? I notice some say 20" shaft, but what does that mean? Also, where's a good place to buy an outboard motor?

I believe that...

...you measure from the top of the transom (or what part of the motor will rest on it) to the top of the cavitation plate. alan

Shaft

I believe most outboards are offered in short-shaft and long-shaft versions without intermediate options.

anyplace that has good prices

is a good place to buy. Some places will bench check the engine before you pick it up. (BassPro will do this for engines you pick up at some of their stores.)If you are buying used - then ask around for someplace that has a good local reputation. Outboard motors can last a long time - with proper care. My father has a 5 HP motor from the 50's that he still uses on a small fishing boat. Don't assume you have to buy new. People are always buying new motors because the one they have is either too big (too heavy for the dinghy) or too small (and they want to go fast).

Long Shaft

I would "bet the farm" that you would do best with a long shaft (20") as the prop needs to be as low in the water as possable. Also, be well aware of the weight of the engine, the lighter the better. you don't need more than 5-6 HP....I used a 4 HP on my O'Day 22 for many years. Suggest you select a 2 stroke, as they tend to be lighter than a 4 stroke...Don't forget you have a sailboat, not a motorboat and will (should?) do much more sailing than motoring.Good Luck!
