Dan;

 

You haven’t said where you sail, nor the reason that you want to put the 
outboard bracket on the transom. As someone else said, there are problems 
inherent in such an arrangement, depending on conditions where you sail.

 

My 25 came with a long shaft 10HP Honda on the back. The early 80s vintage 
Honda was heavy, and the shaft wasn’t all that long. The weight on the aft end 
of the boat probably has some impact on trim of the boat, but the real drawback 
was in moderate to rough chop and larger waves. When the boat starts 
hobby-horsing the prop comes out of the water and starts cavitating while the 
motor races. The only solution is to throttle back the motor to stop the 
cavitation, and then power back up until it happens again. I sail in the Sounds 
and rivers of eastern North Carolina, where waves tend to be short and steep 
due to shallow water, and there have been a number of times when I shut the 
engine off, raised a small jib, and tacked into the weather in order to make 
any progress. And on a couple of occasions the waves at the mouth of a creek 
have trapped me in the creek, and I grabbed a ride home and came back for the 
boat when it was more calm.

 

When the Honda died, I replaced it with an older 8hp Evinrude that was lighter 
and had a longer shaft. Same problem. I now have a 9.9 Taihatsu with a really 
long shaft, and relocated the motor bracket down as far as I could on the 
transom. I’ve not noticed the problem, but I basically only daysail the boat 
these days so I’m not out in crappy conditions.

 

So my opinion would be that if you sail on a lake or someplace where you will 
not need to contend with weather and waves, the outboard will be OK. But if 
weather and waves are in your future, and you have an inboard that can be 
salvaged, spend your money on the inboard instead of getting the outboard. Get 
the longest shaft you can possibly buy on the Yamaha (and look at the 
Nissan/Mercury/Taihatsu motor, which I found had a longer shaft and cost 
several $100 less than the Yamaha I priced). And mount your bracket as low on 
the transom as practical. I have a ½ thick marine plywood backing plate inside 
my transom, and oversized stainless fender washers under the nuts on the 
mounting bolts for the motor bracket.

Subject: Stus-List Mounting Outboard Bracket

 

I  want to mount a Garelick bracket on my stearn to support a Yamaha 9.9 4 
stroke.  I've seen at least on C&C 26' with an outboard; anyone have any 
experience mounting and anything  unusual that I can expect?  Probably better 
off having it done by a professional, any opinions?
