You are probably better off to turn on the water,

The other factor is the hose to the flush port is 5MM ID (less than a
quarter inch) so you are not really moving that much water anyway.

If you really want to flush the block, you need to remove the
thermostat, drop the foot and back flush through the thermostat hole
... but you are not going to do that very often.

These are wonderful, time-consuming suggestions for those who are
retired and have little of importance to do, sort of like painting a
ceiling and watching the paint dry.

I especially like the second suggestion.

The first one is the only way you are actually going to get fresh
water up into the top of the block more than once.
If you want, I can scan the water flow diagram from the shop manual.
The thermostat stops water before it exits the block (that is how it
works).
If the thermostat is closed, you are not going to get circulation
through those passages.


The second suggestion is a maintenance flush

You might want to do that on a 100 hour if that is once a year. I
usually do it at around 300-400 which is once a year for me.

(any time I have the foot off)




Gee, I'll keep all this in mind in case I buy another Yamaha outboard.

Ah yes, the Corinthian leather. There are so many good stories right here in rec.boats. It's a shame
we don't have a historian.

You boys have no shame. Whatever my differences with Dave, he was a
decent writer and contributor on on-topic subjects to rec.boats. Herring
is neither. I have no idea of why you are making fun of his memory here.

I doubt Skipper (wherever he is) would object to a little humor here
and there.

Trust me, FOAD, it's not Skipper who's being made fun of.

Nice try though!

Of course, we all know that most boats are sold at a profit.

I don't remember Skipper mentioning hurricanes but he did tell a story
about "Sudden Onset Tostitos" or something like that. I understand
that the IRS is trying to sell an old clapped out Hatteras with
Corinthian leather seats. Supposedly they seized it to satisfy
certain unpaid judgements in Jacksonville, FL.

That would be just the thing to spruce up that low transom of yours.

I got curious regarding the discussion of rinsing an outboard using
the garden hose flush port versus muffs on the water inlet so I did
some reading. I had a Yamaha 250 four stroke on one of my outboard
boats and seemed to remember reading something about it.

First of all, it is not recommended that the engine be run while
flushing using the flush port. Yamaha states that *if* your water
supply pressure is sufficient to generate a steady stream from the pee
hole, it's ok to run the engine while flushing at idle RPM and for no
longer than 15 minutes. If the flow is *not* sufficient to generate
a steady pee stream, Yamaha says to use muffs in addition to the
flush port if you want to run the engine.

The flush port injects water after the thermostat which will be closed
if the engine is not running. If somehow water can still get down to
the inlet passages and impeller, the impeller won't be turning (unless
the engine is running, in which case it would simply pump the water
back in the opposite direction), so I don't see how it can be rinsed
off. The impeller would tend to seal off any water from running
through it with the engine not running.

So, I still question if using the flush port thing really does
anything to rinse the water inlet and impeller, extending it's life.

Here's some collaborating information:

I don't trust the port and always use the muffs and run the engine.

I'm not convinced that rinsing the impeller does anything to extend
its life. They are essentially self flushing everytime you use the
engine. Sand and shells do not accumulate in the pump and have
already done their damage as they pass through. Pumps and impellers
are not harmed by salt water corrosion, unlike engine blocks,
manifolds, heads, risers, etc.


True. I think you can get salt deposits within the casing though that
harden and might cause premature wear on a rubber impeller, especially
if you boat in the ocean but trailer the boat home at the end of the
day. My point in this discussion was that using the flush fitting
doesn't necessarily mean you are flushing the inlet passages or
impeller area. The Yamaha outboard I had was equipped with the flush
out port but when I hauled the boat I always flushed it with a muff
over the leg inlet screens.




Yup. Better safe than sorry as they say.
