    QuickSilver Power Tune Spray - worth trying??

    Texasmark, so I'm all set now. Good learning experience for me. Going forward, when fueling my boat I'm going to always use the "Mercury Component Cocktail" which is 5 gallons of non-ethanol gas, 1 oz of Mercury QuickCare, and 1 oz of Mercury Quickleen. I've heard good things about this...

    What octane gas?

    I have a 2001 Mercury 90 hp 4-stroke that is NOT fuel injected. I have ALWAYS used no ethanol gas, which in my county meant I had to use premium gas that I think is 93 octane. Recently the Fleet Farm gas station began offering no ethanol mid-grade, which is 87 octane. Which is better for the...

    QuickSilver Power Tune Spray - worth trying??

    To clarify, I unhooked the vapor recovery hose and sprayed Power Tune into that hole, which seemed to be a more direct route to the carb intake. FYI I had decided against my previous idea of removing the fuel line and spraying Power Tune directly into each carb. Hope that was OK to do.

    QuickSilver Power Tune Spray - worth trying??

    Sorry Texasmark. I got a little confused as to why a second person needed to crank the engine. At any rate, here's what I did....I unhooked the vapor recovery hose located above the air intake screen. Then with the engine running and throttled up a bit I sprayed Power Tune into the intake. Short...

    QuickSilver Power Tune Spray - worth trying??

    OK, good point. So I need someone to crank the engine - meaning crank the engine without it starting? Meaning pull a spark plug wire and then turn the key? Just for my own education, why is this important?

    QuickSilver Power Tune Spray - worth trying??

    Texasmark, in addition to my previous question shown above (spraying Power Tune into plenum), I had one more question...... a friend of mine suggested draining the carburetor bowl(s), which is easily done because the brass screws are very accessible, then retightening the brass screws. Next...

    QuickSilver Power Tune Spray - worth trying??

    Good thinking Texasmark, so let's review. The plenum and runners are one-piece (actually two molded pieces of plastic permanently glued together......I read that in the manual). To remove the plenum assembly you'd have to remove some other bolted-on parts first; I've already decided against...

    QuickSilver Power Tune Spray - worth trying??

    These pics should help. I tried to focus on the area where there might be ports to access the intake, where the plastic is bolted to the metal, and where the two plastic parts are (presumably) glued together permanently.

    QuickSilver Power Tune Spray - worth trying??

    Yes you're right about that. I will provide better pictures for you ASAP. What I initially thought is that the plastic plenum (with the 3 bolts aligned vertically) was a separate plastic part from the horizontal round "tubes" that (presumably) would lead to the carb intakes. But what I found out...

    QuickSilver Power Tune Spray - worth trying??

    Thanks Texasmark. Actually it's a four stroke. If you look at the photo, I thought I could access the carb intake by removing the plastic plenum but it doesn't come off. Note the three bolts I removed. How can I identify the correct holes to unplug? I can send a better photo if that will help.

    QuickSilver Power Tune Spray - worth trying??

    I have a Mercury 2001 90 hp 4 stroke outboard. NOT fuel injected. I want to spray this Power Tune into my carburetor intake but don't know how to access it. Would appreciate some advice.

    2001 90 hp 4 stroke carburetor intake- how to access?

    I want to spray some Quicksilver Power Tune into the carburetor of my engine. This is NOT fuel injected. I'm humbled to say that I cannot figure out how to do it. Please advise. Thanks in advance.
