I stay on the lookout for a small 4-stroke outboard to mount up as a companion to my 175 Johnson. My boat has a full transom and I can't seem to find much information about the importance of motor shaft length in my decision. There are a lot more short-shaft motors in the 10-15 hp range than there are long shafts.

I'm concerned that a short shaft motor will be tough to manage when I bend over the end of the transom to raise and lower it with say, a Garelick spring-loaded bracket, but I don't know if that needs to be a real concern. I'm not planning to spend $1K + on a hydraulic mount.

How much leverage do those spring-loaded brackets give? Do they really provide a lot of "lift" to help one pull up the motor, or is it minimal? I'm no spring chicken, and I have this vision of throwing my back out or dragging myself right over the stern trying to raise one of these things.

What are your experiences with the mounts and what are your recommendations for motor shaft length?

Finally, even though the aux will be mounted off to one side of the transom, I assume that in running position, the aux's cavitation plate should be positioned at the same depth as the primary motor - about even with the keel. Right?

Re: Questions About Mounting and Auxiliary Outboard

you are correct in motor height, and need a long shaft. some of the mount are spring loaded some aren't.

Re: Questions About Mounting and Auxiliary Outboard

I have the Garelick HD bracket with 9.5" of travel and have been happy with it. The springs are very strong, my motor is listed at 115 pounds and I would say that it feels like you are lifting no more than 20 pounds. I have the 20" long shaft motor and think it is a good length. For me 15" would be too short and 25" would be too long. The Garelick website has detailed instructions on how to figure the mounting height of the bracket and motor. On mine the kicker cavitation plate is not nearly as low as the main motor.
