Fresh Water Rinse
- Thread starter dotnmarty
- Start date
Getting advice from me is like asking a blind man for driving directions, but I'm not shy so here goes...
It is my understanding that it isn't so much where you store your boat* but where you use your boat that matters.
When you use your boat in saltwater all the time, the salt may start to accumulate in the water cooling lines internally in the motor (just like it does on the outside of your boat after a splash). This salt along with other miscellaneous crud that you've motored through may affect your motors ability to cool itself in the future if the pathways get clogged. This of course is in addition to the effect salt has on the acceleration of rust within the engine.
Flushing an engine should be possible while on the water. I realize I have a different brand motor than you, but as new as yours is it should have a flush port that simply hooks up to a hose. My boat is moored in Edmonds and I've gotten into the habit of flushing mine after every use.
*My engine manual (Mercury) also states that if you store your boat in saltwater all the time you need to spray the motor itself (under the cowl) with anti-corrosion spray regularly.
Hope I didn't embarrass myself.

Marty,
I don't think you have to pull the boat to flush the engine. There have been some past discussions on this issue, and my vague memory is that there is a benefit of flushing (on engines with a flush hose attachment), even if you leave it in the water.
There are also some bucket or bag setups I think.
The newer Hondas have you hook up a hose and flush fresh water thru without running the engine, so ear muffs would not be needed if that's the case on your outboard.
Hopefully, one of the dealers will chime in on this!

John- The manual says that there is a flush port, but an optional garden hose adapter is required. It also says that the motor needs to run during flushing and, additionally, it says the prop shoud be removed for safety!. (I wonder how many people do that?) Lastly, the flush port is located just above the permatrim, so I might as well use the muffs. Unfortunately I dont have a swim step so It's just out of reach when the boat is tied up. Anyway, the whole manual is free on line

I have an 01 Honda 90 - the owners manual that came with the engine shows on the back of the engine just below the engine cover a round black plastic plug that can be removed (pops right out with a screw driver) - once uncoverd there is a connector for a rinse device called a "water hose joint" that can be purchased at any Honda Dealer for $50.00. The engine is not on and when rinsing water comes out of the "pee" hole.
Page 104 of my owner manuel shows the water hose joint and the location of the water hose joint. I curise and salt water so i reinse after each use.

I have been mooring at the Everett Marina since I got my boat, about 5 years. You positively still need to flush and should do so after each trip. I have the twin Honda 40's and you may have seen my recent posting about gas in the oil. As explained by Les, this is caused by the thermostats becoming stuck open. The engine runs very cool and doesn't burn all the gas, which ends up in the oil. I just changed the thermostats and will put the boat back in the water this week (I hope). I back my 22 foot into our slip, then tie it up so the engines are very close to the main dock. Raise the engines some, add the ear phones, turn on the water, lower the engines back into the water and start them back up and flush. I have done this almost everytime I return, the exceptions are when we are late for whatever reason. I was still amazed at the amount of salt built up in and around the thermostats.

I just flushed my Honda 90 thirty minutes ago using the attachment mentioned by ken 120 in this thread.
FWIW: My first year I'd flush after every use - I keep the boat at a municipal slip. Last fall it was pointed out to me by the Honda dealer that, while this is SOP, folks on a mooring who don't have access to a fresh water hose and can't flush all the time and the Honda engineers know this.
BTW: I believe the port for flushing doesn't impact the impeller which is why you still need the ear muffs when running the Honda out of the water.

Marty;
IMO, I feel that if you have the means to flush after each use, go for it. It is time well spent. It is almost like pay me now , or pay me later view. I try to do this every time my CD25 is used.
My HONDA 90s are flushed with 'Sat-Away' through a garden hose adaptor "Y" so I can do both engines at once. It is amazing to me to see how much cleaning action occures.
I bought the 'Y' adaptor at Home Depot and each branch has its own cuttoff. Now it takes me 1/2 the time to flush both 90s, and a side benefit of controlling the individual h2o flows.

Marty mentions using his earmuffs to flush, others mention hooking up with a hose to the connector on the engine - why do one or the other?
If I have a connector on the engine that a hose end goes into - does that do as good of a job flushing as using the earmuffs? I've heard from some folks that you should always use the muffs, but it seems to me if the manufacturor puts the connection on the engine it must be designed to do the proper flushing.
Thoughts ?

If you use the ear muffs, you will be flushing thru the water pump impeller. If you use the in the block type of fittings, The vane type water pump may not be flushed in some engines. Some engines have a water pump bypass when block flushing, so that the water goes thru the pump.
If you run an engine, with no water lubricating the water pump, then the water pump vanes will burn up and fail in the engine where the manual cautions against running the engine when block flushing.

When we bought our boat, I was warned by the dealer that Honda
published some manuals with incorrect info with regard to running
the motor with the garden hose attachment.
You probably do not want to run the motor with this method of providing
water unless you are certain the water is going to flow through the
impellor.
You can run the motor with muffs, of course.
The salt line does not extend to where I slip our boat and I've never
seen anyone flush an outboard in any local marina, so I do not
worry about it. If we come in at low tide, I'll raise the motor (but keeping
the intake in the water) and allow it to run for a while.

So this may be obvious to some, but when running with earmuffs or the garden hose attachment on the motor, is the motor tilted down in the water, or up?
The engine should be in the down position when running. This has nothing to do with flushing but with the engine oil level in the crankcase.
When running my Honda 150s on the earmuffs while on the trailer, my overheat alarm sounds after about 10 minutes. The temp indicator doesn't show overheat however. :?: :?:

Its that time for antsy folks to pull some maintenance and I wonder if some one might have and answer to a cooling system issue? I wanted to run the motors to check everything after a tuneup but couldn't get water to come out of the pee tube.. I checked everything and tried a flush nozzle and still wouldn't come out.
The impellers were only a year old, so didn't seem like that would be the problem so I eventually had to fill a tub with water that completely covered the inlets and finally water came out fine.
Shouldn't water come out with just muffs on or with the flushing nozzle? thanks michael

You may have a spider or another such critter in the pee tube. A pipe cleaner or something of that nature usually cures the issue. It happens to my kickers all the time.
