Mild smoke from 330ex

[FritzB141]

Hey Folks-

It's been about 5 months since I last ran my 06 211. I'm about to tow it north for the summer so I decided to get it into "ready to go" condition. One of my first projects was to run the engine and charge the batteries. I'm no where near a body of fresh water so I decided to use the flush kit and fire it up in my driveway. After getting the engine started (the batteries needed a jump) I turned my hose on with mild pressure (as my dealer instructed) and paid close attention to the exhaust to see how much water was getting through. Water began to drip from the exhaust and I periodically checked the engine temperature. The temperature settled at about a 154 degrees and all was well (it had been about ten minutes at this point).

About two minutes later the engine shut off abruptly. I looked at the engine temp and it was still at 155 and then looked at the motor. Mild white smoke came up through the bottom of the motor for a very short time. The engine wasn't hot and all of the hoses seemed to be in working order.

Why did the engine shut off if it wasn't overheating? Any ideas as to what might cause smoke in the situation? Was it lack of water pressure? Any ideas will be greatly appreciated.

RE: Mild smoke from 330ex

don't know about the engine shutting down, but I do know you should have had more than just a little water dripping from the exhaust. Turn the water pressure up for sure. Not to sound insulting but did you check the fuel level.

There's plenty of fuel. Water Pressure was more than dripping. I probably should have used a different word. I don't use full pressure because I blew a hose off once and it was a royal pain in the a%# to get it back on. However, I still thinks it's possible that there wasn't enough pressure. I'm in pursuit of the happy medium. Thanks for the reply Jward.

the smoke was more than likely just steam if you ran it that long. Did you ever rev the engine or did you leave it in neutral the entire time?

[jward]

Also, have you tried to fire the boat back up since it shut down. If so what happened

[tadelfio]

Not sure of why the engine shut off either but I do agree that as long as your temp gauge is working correctly then the smoke was probably just steam. I do not turn my water up all the way either because I too have caused a hose to pop off due to excessive pressure. I do have pretty good water pressure at my house so it is tuff to say what is too much for someone else.

[FritzB141]

The engine shutting off is my major concern. I felt it must have been the computer protecting the engine from damage. The question is....what damage was I causing if any?

Jward- to answer your questions: Yes I did rev the engine and no I didn't fire it back up. The batteries were still too weak to turn over the engine. Thanks for your replies.

You should never take the boat out of idle when on the hose because the hose doesn't provide enough water pressure when the boat is taken out of idle. If you are going to trailer the boat a good distance to water I would check the impeller.
I wonder if you may have a bad cell.

[FritzB141]

I bet you're right. I didn't rev it above 1000 rpms, but I agree that reving was a bad idea. It couldn't find the water it was looking for with the low pressure. I'll check the impeller and it should be good to go when I dunk her. Thanks for your input.
