Read what this guy said about how you said to tune the boat. This was on another form where I was trying to help a guy.

I've read a lot of bad advise on this forum but running a boat on the stand, wide open, has to top them all. If you want a basket of broken parts, that's the best way to get them. The mixture needle on a boat ENGINE is set on the water. That doesn't mean you have to run along side it and adjust it. It's a trial and error process. Set it rich on the beach (usually 2 to 2 1/2 turns open - check the engine manual) and launch the boat. The ENGINE has to be under load to set the needle properly. Run the boat and observe the exhaust trail. Heavy smoke means you are to rich. Bring the boat in and lean the mixture. 1/4 turn at a time is usually sufficient until you get close to optimum. Continue that process until there is light visible exhaust smoke and the ENGINE will hold RPM at full power. No loss of RPM in the corners and good response during throttle transition from low to high speed. Also look at the glow plug. If it's visibly wet after a run, chances are the ENGINE is running rich. If the plug coil is distorted after a run, the ENGINE is to lean.

You're local hobby shop should be able to get you in contact with an experienced boater. Seek his/her help, but PLEASE DO NOT TRY TO SET THE MIXTURE NEEDLE WITH THE ENGINE AT FULL THROTTLE OUT OF THE WATER!

I wouldn't do that either. I do give the throttle quick blips to check to see how the mixture is set. If you have help, I have held the boat in the water to tune it for just a short period, a second or two but I wouldn't do this with a large boat as it could get loose. You have to really watch what you're doing then, especially with the spinning prop.

Yes I know, Thats what I was trying to tell the guy. I said run it up for a quick second to check for smoke.

Hmm, Well I Have Checked The Needle Mixture That Way For Years! Go Figure. Nothing Has Ever Gone Wrong Or Broken. Then Again Im Not A Beginner. And Usually Do This Within A Second. I Can Set The Mixture And Toss It In The Water And Usually Right On The Money. This Is Of Course Done Only If I Percieve That Something Is Wrong. Dosen't Happen Often. :)

:) Your Welcome! I Will Say Who Ever Made Those Statements Is Pretty Much Whack. :d Because If That Was The Case Engines Would Be Blowing Up All Over The World.

If Your Boat Comes Out Of The Water While Running At Full Throttle Thats Even More Stress. Ie: Jumping Waves, Flipping Ect.
The Key Is Quickly, If Your A Moron Then I Can See Somthing Happening.

I think maybe he just wanted to impress more than listen. I've always done it out of the water first.
