is the forum sending out emails weeks after they are originally posted (the
date on the email below came across as 3/19/07, received in my inbox 3/26/07)?
regardless -
the debate if a honda 2H motor needs to be 'flushed.' (my comments below
relate to my engine, an '05).
putting 'water cups' over the exhaust holes would send water INTO the
engine of a honda 2H. the motor does not use water for cooling. it is air
cooled. the exhaust is also cooled as it runs down the shaft. from honda's
site:
Cooling System - Forced Air
(http://www.honda-marine.com/modelDetail.aspx?modelGroup=BF2)
the contrasting to the 5H honda (again from honda's site):
Cooling System - Water Cooled
(http://www.honda-marine.com/modeldetail.aspx?modelGroup=bf5)
i had a discussion with my honda marine mechanic about this back when the
motor was obtained in summer '06. he stated that water will 'back fill' into
the exhaust holes below the waterline (when the motor stops). there is no
water pump/impeller and therefore the only salt above the water line is from
splash. he did say it is a good idea to spray the motor down after salt water
operation. besides checking the zink, running good gas, and following the
maintenance recommendations this is all that is necessary.
i do run the motor in the garbage can when i return from a trip/sail (have a
designated can that sits within the motor stand). i figure 'better safe than
sorry' and do this fresh water bucket run to assure (as much as i can) the
exhaust 'runs free.' while the motor is running i give it a complete
'misting'. it then goes into the garage until the next trip.
now, this is different than what i would do if i had a 5H motor -- but i need
a M17 for that (one can dream).

All,
Does anyone know of an easier way of flushing a small 2hp motor without using a
trash can? I don't always return home after a sail and I'm looking for a quick
and easy method of flushing my motor while traveling. The traditional flush
cups are too big and will not fit over the intake hole due to the location of
the hole.
Has anyone ever tapped the the intake hole and used a small fitting. I was
considering using a small male fitting with a gate valve (for adjusting flow)
connected to a short tube that connects to a traditional hose fitting.
If anyone has an easier, tried and true method, I'd appreciate it if you'd
share.
Thanks in Advance,
