O5 Tige Vortex 5.7 Question.

[flyboy]

Hey guys,

shortened season here on the lake in NY...they lower the lake every three years so folks can do needed repairs to their bulkheads.

I have a Fake-A-Lake question.

I usually fog the engine while on the trailer in the lake, but I'm going to take her out on the Hudson once or twice before the season really ends.

So, I made a fake-a-lake as shown in the pix below, but I'm wondering where is the best place to hook it up to while out of the water. Looking in the engine compartment, I see a hose hooked up to the intake from under the boat....see pix also....


Is this the best place to run the hose to/from? TIA!

[chpthril]

That will work just fine.

Thank you for the quick response

Just be sure you don't run the engine above idle because that hose diameter is only 5/8" on your apparatus and can't flow enough water at higher engine speeds. As a note, Perko makes an inline "Flush-Pro" Perko part# 0456DP7 (1.25" hose) for $91 at west marine so it's way cheaper somewhere else online. It has a springloaded mechanism inside that keeps the water from flowing out the intake when water pressure is applied from a garden hose. You could also make an external fake-a-lake from a toilet plunger and hose fittings.
FYI, DO NOT FOG multiport injected engines! The fogging oil sticks to the injector tips and holds them open and/or sometimes just clogs them! Instead, run a small batch of stabilized fuel from a separate tank through the system and shut it off before it runs out of fuel.

Wouldnt the Flush-Pro still be fed by the same garden hose?

[boatwakes]

Not necessarily, I was referring to the diameter of his flush kit being 5/8" but if you're household hose is also 5/8 then you're right, you run into the same problem. 3/4" preferred but you get the gist. Good luck.

So that's all that is required to run the motor at home is an adaptor to the intake into my garden hose huh?

What happens if the garden hose pressure pushes water? Why is this bad?

The problem with a fake-a-lake on a typical house-hold water supply is that it may not supply enough water to keep up with demand if the engine is run too high above idle. This can lead to running the impeller dry or a higher then normal engine temp.

[Fiveflat]

So nothing particularly wrong with the garden hose pressurizing the system? Or will that pressure turn the impeller?

Sorry if my questions are a sort of hijack...

No, just not recommended to run the engine much above idle for long periods of time.

First I'm hearing of this after numerous multi-port engines...I would like to hear more on this issue and from Tige direct if possible.

FYI, I fog at idle until she stops running, then I close her up for the season.

Fog it. I fog mine. Oil does not clogg injectors.

This has been a debat for a few years now. I have heard of manufacturers either not recommending it or warning against it (not sure which), but I have never read why in anything from a manufacturer.

IMO, fogging will not harm an injector. You have 35PSI of fuel spraying across the injector pintle (needle & seat where the fuel exits) as well as 17 inHg (vacuum) pulling the fogging oil toward the cylinder.

[ajholt7]

I just don't see oil clogging anything. Dirt in oil might clogg something but oil doesn't clot. Ask BP!

This is from the Mercruiser service manual:
Power Package Layup

1. Fill fuel tanks with fresh gasoline that does not contain alchohol and a sufficient ammount of Quicksilver Gasoline Stabilizer for marine engines to treat gasoline. Follow instructions on container.

2. If boat is to be placed in storage with fuel containing alchohol in fuel tanks (if fuel without alchohol is unavailable): Fuel tanks should be drained as low as possible and Quicksilver Gasoline Stabilizer for marine engines added to any fuel remaining in the tank. Refer to "Fuel Requirements" for additional information.

NOTE If desired, a portable fuel tank can be used to perform the remainder of the power package layup procedures. Be sure to add an appropriate amount of Gasoline Stabilizer to the portable tank.

3. Run engine sufficiently to bring it up to normal operating temperature and allow fuel with Quicksilver Gasoline Stabilizer to circulate through fuel system.

4. Shut off engine.

5. Change oil and oil filter.

6. Flush cooling system. Refer to "Flushing Cooling System" procedure.

7. Close fuel shutoff valve, if equipped. If no fuel shutoff valve is present, a suitable method must be employed to STOP the flow of fuel from the fuel tank to the engine before proceeding.

8. Prepare EFI fuel system fo extended storage as follows:
a. Allow engine to cool down
b. Remove the water separating fuel filter
c. Pour out a small amount of fuel into a suitable container, then add approximately 2 fluid ounces of Quicksilver 2-Cycle outboard Oil to fuel in the water separating fuel filter.
d. Reinstall water separating fuel filter.
e. Start and operate engine at idle speed until the water separating fuel filter and fuel injection sustem are emty and engine stops.
f. Remove and discard water separating fuel filter.
g. Install new filter.

9. Prepare [COLOR="black"]CARBURETED fuel system for extended storage as follows:
a. REmove flame arrestor assembly and start engine.
b. While operating engine at fast idle (1000-1500rpm), fog insternal surfaces of induction system and combustion chambers by squirting approximately 8 ounces of Quicksilver Storage Seal or SAE 20W engine oil into carburetor bores.
c. Squirt the remaining 2 ounces of Storage Seal rapidly into carburetor, just as the engine begins to stall, due to lack of fuel. Allow engine to stop.
d. Turn ignition key to OFF position.
e. Refer to "Flushing Cooling System" and appropriatelyt remove water supply to the seawater pickup pump.


Just making sure none of you are incorrectly informed as to what we as Mercruiser techs have access to in the manuals. Good luck!
