The "trick" is to have the boat and engine in the water - on a trailer or well tied to the dock and IN Gear.  That gives enough resistance so that you don't get the run-away in Neutral.

The directions on the Engine Tuner do say to have the engine running, although Rick's method sounds good too.

Regular use of the Fuel System Cleaner, along with some EV Carbon Guard on maybe alternate fuelings should help keep you good.

I'm surely no expert, but here's my regular fuel mix found through my learning on here from the pro's:

Per 5 gallons of fuel - 3.5 oz of your engine oil (helps lube injectors and HP fuel pump), 1/2 oz of Carbon Guard (lot of low speed running), 1/2 - 3/4 oz of StaBil 360 Marine (protects and lubes whole fuel system).

Hope it helps!

Phil

Just as a note. The directions on the spray can of engine tuner states "run engine at high idle and spray into carburetor throat(s).
There are nod directions on the can for fuel injected engines with a throttle body.

++ to Rick!  I just "assumed" that with the air box removed it was essentially the same thing - carb or injected.  Running at high idle worked "fine" for me (in gear) - the spray got sucked right in past the throttle plates to get in there and do its work.  [smile]  Two or three tight ropes holding the boat back from climbing up out of the slip onto the marina walkway, and all went well.

Rick's method does sound good, just that I never tried it myself.

Phil, the tuner sprayed in the throttle body can do some cleaning of the throttle shaft and Reed valves.
Now, just some of my personal theory.
Tuner sprayed in the throttle body will have a percentage fall down or so the lower Reed block and cylinder gets more tuner. As the tuner travels through the crankcase it, in theory, washes some oil off the bearings then enters the cylinder intake ports.
Like a lot of cleaning procedures, they work just fine in moderation, but can be harmful when overdone.

Some interesting points there, Rick!  [thumb]

Surely not 'debating' with a Pro (I'll lose!), but wouldn't the spray through the plug holes to fill chambers also wash the oil off the cylinder walls, rings, and pistons?  It almost seems like MAYBE a choice between "lost compression" vs "maybe Bearings" when the oil gets washed off of 'somewhere'?

I truly don't know, and do think your method does have Merit!  Moderation is key, as you say.

Best at ya!  [smile]

Phil
