Garden Hose Flush vs Muffs?

[DennisG01]

In regards to the garden hose attachment on the side of the engine (2000 250HP OX66, if it matters) for flushing the engine or using the flushette attachment (muffs) on the intake... Do both methods work equally well for flushing the engine? Are there any downsides to using the garden hose attachment on the side of the engine?

Everything I have read says the hose connection is for flushing the power head ONLY! do not run the engine! you can ruin the water pump from lack of water.


The muffs supply water to the water pump.

Thank you. Yes, that part I am aware of. When using the hose connection (boat is in the water right now which is why I can't check myself), will some water backfeed down through the lower unit? Will it backfeed enough to flush things out as well as on the muffs?

Can't answer that one...

But it does run out the bottom at a pretty good pace on mine.

Awesome, that's perfect. I may need to fog at the ramp (salt) and then flush afterwards, hence the question about whether the garden hose attachment is sufficient. Thank you!

Your welcome..

Just as a side note, (I'm on a boat lift), as soon as I come in, the powerhead adapter gets the hose for at least 15 minutes..

Then, the muffs come out for another 10-15 minutes.

Then I flush the speedometer pitot tube (they like to clog up).

Then soap and water to everything and a pump of yamaha grease to the main steering pivot..

I hear 'ya on the pitot tube. I've boated my whole life (and have worked part time/full time in the marine industry for about 26 years), but am much more familiar with stern drives, inboards and smaller OB's. With the Grady being in Maine (on a mooring so it can't be flushed regularly), we don't have as much of the "salt" issues as you do down South since it's not "in the air" like it is down there. The pitot's still sometimes get clogged, but it's because of sticks or debris in the water. A small drill bit always takes care of that.

I can tell just by looking at your lift that it was built for boat maintenance. Very nice.

Haven't had a bike for a few years now... but nice bike!

Thanks re the lift and bikes!

BTW, even with the boat pitot tube NOT easily accessable, I "Tee"ed off the the line/hose going up to the speedometer and put in a shrader valve.

With a small 12 volt pump, I simply snap it over the valve and is blows ALL the water, out of the speedometer hose/ line. I was surprised how much water came out initially(1/2 cup maybe) under the floor and out the tube the first time. It'll blow just about anything out of the tubing and aluminum LU as well..

Its an easy mod and the speedometer hasn't been this accurate since new...
