I'm back home from our haul out on north Key Largo, Manatee Bay Marine. This
was our third time at MBM, and we've been very pleased.
As for the removal of the lower leg of our Yamaha's, I once again had the
opportunity to practice while working from my dinghy. While on the hard, I had
changed the lower unit and motor oil and installed a water pump rebuild kit on
each motor. I assumed that all was fined when we we're put back in the water
to begin our 25 mile sail back home. One motor, the same that had not been
squirting much water as of late, began running rough and dropped its RPM due to
overheating. Once back on our mooring, at the marina, I worked from our dinghy
to pull the lower leg of the motor, 3 times. I wanted confirmation that the
impeller was properly installed, and still no water from the tell-tale.
One motor has a strong stream of water. The affected motor only squirts or
spits. I'll be back on the boat tomorrow to remove and test the thermostats.
I'm afraid the water cooling passages mat by clogged. Has anyone worked
through this issue? What did you do to correct it?
Back to working from a dinghy to remove the lower leg. We use a Walker Bay
rowing dinghy to get out to our moored boat. This dinghy may be easier to work
from due to its lower free-board. I put my weight in the rear of the dinghy
and back it under the tilted lower leg. I then loosen the shifting rod nuts
and remove the 4 nuts holding the lower leg to the upper section of the motor.
The leg slides down into the dinghy and you must be careful to bring the leg
"insert" with the lower unit so that the insert does not drop off later into
the water. The only thing I do different when re-installing the leg is to
have a helper sit in the dinghy with me and hold the dinghy with pressure
forward. Otherwise, when I try to align the drive shaft and shifting rod,
while lifting the leg, the weight and force push we away from the motor.
Another option would by to anchor in a calm, shallow place where you can stand
on the bottom to remove the lower
leg. This is how I plan to do the work once we begin cruising. 12 days, but
whose counting.
It works for me, I hope this helps.

I'd like to know how you pull off that magic trick! I've done things from the
water and it is a pain when i'm in my spare dingy. Get back. Bye the way,
what key are you on? gene

Hey guys, I've only a second. I'm home from the boat yard in the Keys for a
shower,off to a meeting, and then back to the boat for several more days.
There is no internet there.
I'll try to make sense of Joe's idea for pulling new wires through the mast.
As for the motors, I have removed the Yamaha lower units several times while
the boat is in the water. It's a fairly straight forward using the Seawind
instructions. I then have the choice of working on the boat or taking the
lower units home.

Check this for Seawind's detailed instructions, page 6:

So what I was really wondering is if anyone is changing gear oil using this
method, and what problems might be encountered.

Ok, I read the comment wrong. The Seawind method has the motor tilted, and
the lower unit removed completely using a dinghy. Then you disassemble
and
change out water pump and lower unit gear oil.

Not me. Every mechanic I asked about doing that says its not a good idea as
you can't get enough
fluid out or in.

Hi Mike, what's the Seawind method? Doing it on an angle in the dingy?

Consider how much trouble it was to remove the wiring and the
linkages, does anyone just remove the lower leg while the motor is still
attached. For instance, how many of you are using the Seawind method?
