Quicksilver Power Tune

[alystra]

Hi Chaps,

Quicksilver Power Tune. Is it 'snake oil' or does it do some good? The instructions seem very off putting.

Run 2/3rds of contents into carb throat (?? I've got four of them, do I need four cans?) while engine running at 1200 rpm. Increase speed to 2000rpm and stall the engine with the rest of the stuff . After a bit start and run at 5000rpm for 5 mins. Will that be the end of my engine? What is this stuff? Will my engine get addicted, like a diesel to Easy Start?

I wondered if it might fix the odd missfire and spit back on tickover or fast idle, which I thought might be caused by carbon buildup or a sticky valve. Engine's 8 years old and not been heavily used. Any thoughts? Anyone with experience of the stuff?

I'm conscious that Quicksilver are Mercury, and Mercury want to sell more engines.

Cheers Tony

powertune is a good de-carbonizer/cleaner i have sqirted it down the throats of carbureters and striped and cleaned carbs out on site and in the w/shop cleaned the top of my work bench (yes i know the people that know me will say i have a wooden bench but it still cleans it just mind the splinters) it is a damn good cleaner.

i forgot to say when you spray down the carb when running it smokes like hell and you require about 1500rpm

It is good stuff-I use it for cleaning fuel system parts too.

uncle AL uses it to clean his kitchen table at home aswell .

I used the evinrude equivalent and followed the same instructions using a couple of cans on on old V4 Johnson.

To be fair I think if you are using good oil and fuel then unless you have clocked up 1000's of hours its ulikely you are going to have major carbon buildup.

Many thanks guys. It seems it doesn't do any harm and might do some good. Might as well use it now I've got it.

Chris. I'm sure you're right. Looking down the plug holes it didn't seem particularly nasty.

Uncle al. Thought it would be smoky. It'll cause some gossip hereabouts. Mate of mine cleaned his ancient diesel engine out with Redex (don't know if that's still available). The smoke was so thick it filled the canalside 'marina' till you couldn't see one end from the other. It gradually poured out of the entrance and down the canal.
