My brother is in town this week on vacation and we borrowed a boat from one of my uncles. I recently sold mine, so we borrowed his to go fishing. When we got to the lake, it was a little low, as it has been for a while. Well when I backed the boat in, in order to get it off the trailer I had to keep backing up. I had to go to the point where my dual exhaust tips were pretty much submerged. And they stayed that way for about a minute while they cranked the boat and finally got it off of the trailer. Then when we loaded up, we had to do the same thing to get it loaded. The ends of both tips were under water. I didn't look, so I don't know if the entire tips were under or just half of them. But I noticed the line from where they were dirty and wet went all the way around the tips.

I just want to know will that cause any problems and if so, is it something major or just maybe minor things. I have had a boat for several years and never had a problem like this, but this boat was bigger and heavier so it was a little harder to unload and load.

 

I'm not an expert but if the truck exhaust is the same as a four wheeler exhaust I don't think you should have any problems, as long as you didn't suck any water in to the engine, I know I have had my Yamaha exhaust submerged and as long as it was blowing outward I was ok. Has it been running weird since that day?

 

That water evaporated quickly when you drove off. Nothing to worry about. Water is produced when you burn gas, so your exaust always has water in it.

 

Your only problem will be corrosion.

It won't bother the engine at all. All marine engines exhaust underwater, except of course the hi-po guys with the thru-transom cannons.

As long as your engine exhaust ports are above the waterline, you'll be fine. Well, other than all the other problems being that far in the water would cause.

You might want to have a look under your rig and see if you have breather pipes on your diff(s) and where they breathe from, and then don't go wading in water that deep.

 

I agree that the exhaust is fine. I agree that you should be more concerned about your rear differential. It wouldn't hurt to see if your vent tube is functioning properly and if your gear lube is ok.

 

Thanks guys. I just wasn't sure about it and figured I would ask some of you guys that might know more about it. My parents and brother kept saying it would be fine as long as I kept the engine running. I don't think I got the rear end under the water, its just that I have duals out the back and they are what got under water. As far as them corroding, they are already starting to rust a little bit as they are only the chrome ones. I need to have them replaced with some stainless steel ones. Thanks

 

The only time submerging the exhaust will hurt is if you shut off your truck. I did this 4x4 ing and filled the muffler full of water it caused the truck to back fire.

 

YUP!

 

With my truck lowered 4" in the rear and this one lake we take the Yamaha 135hp to, the boat ramp is really shallow so you have to back way down the sucker. I almost alway's get water in the bottom of the tips (they are in front of tire) and the bumper is underwater almost. Sucks

 

You won't have any problems migth be a little rust but if you keep the truck running you'll be fine as far I'm know. I go off roading enough to no as long as you keep exhaust coming out your fine.
