I dont know if its the pitch of the boat launches around here or what but I cant seem to launch or pull out any of my boats without putting my exhaust in the water.
I have read that I shouldnt put the exhaust in the water because the truck might stall. I have also heard it can do worse to the engine. But I dont know whats true.
What is the deal? Can I drop the exhaust in for 20-30 secs or is this a big no-no?
Any other thoughts?

Other than salt water eating at it, I've never heard of any issues.... I've also never heard of anyone stalling from submerged exhaust.... Maybe on a 1L 3cyl Geo Metro.... But highly doubt it could stall a V8....
The launches grade....length of boat trailer(tongue), and when you're launching(tide) all play a factor.... I submerge mine all the time on low tides(ocean connected lake), and never have any issues stalling, even at idle...
Even if it did stall, it wouldn't hurt much. I'd only advise trying to keep your axle from being submerged.... and don't do this...
you should never have to submerge the exhaust in the water to launch your boat. what type of boat do yo have? The only reason I ask is because I work on boats and have never had to back a truck in that deep to launch or retrieve a boat.
We're spoiled by the boat ramps in Jupiter, especially the east ramps at Burt Reynolds Park, those suckers are steep, even at low tide. But I've launched at many ramps throughout Florida and havent soaked the tail pipe yet. That being said, I've seen people soak their tail pipes a bunch of times and havent seen a stall yet.... doesnt mean it doesnt happen but I do see submerged pipes a lot.
but aside from that, ive never had the need to get mine that far in...maybe if i was marky mark and had a slammed bagg'd truck that was close to the water but not on a stock or higher truck....
i back mine in, i guess we have steeper ramps, at all the ramps ive ever used and just back it in to the top of the trailer fenders and drive it off/drive it on..i dont get in far enuf to float it off w/o engine power but its barely gripping when i put it in at that level so it wont float away from me or across in a sideways current...
You are fine. Just don't turn the truck off. The only issue I have heard is water being sucked up into the exhaust if you turn the truck off and start it again. Even that though seems far fetched, as the water has a LONG way to travel up the exhaust system.
The ramp at my lake (man made) is very very shallow, so you need to back in to where the front tires are at the edge of the water, just to get the boat close to pulling off. Never had an issue. PITA, but you can't beat the glass!
Yeah, as everybody has said, don't turn teh truck off.
If you're blowing on a straw, what are the odds of water getting to your mouth from the other end?
Especially with the grade. EVEN if you turned teh truck off, the water is not goign to get UP the exhaust pipe and ruin the motor.
This is more if you're ENTIRE truck is udner water.

rock there are some circumstances if u are on a not too steep ramp and when u turn it off that the motor will cause it to suck back up the pipe not just run up hill...so it could and can happen...but still i dont see the need to back in anywhere near that far...

Yeah, that's true. It does suction a bit so it could get up there.
Don't forget, cold water can crack a block too! haha. My buddy's Jeep ahs been through so many cold water crossings that if his hasnt' by now, it sure as hell won't lol

thats kinda one thing that alot of boaters have actually had happen...they go flyin across the water and accidentally pull their kill lanyard and engine dies but sucks water up the risers into the manifold lcoking the motor....
Does that suction have anything to do with how fast the engine's turning?
I could see that if it's turning 5K rpm it's gonna have a lot more suction when immediately shut off htan an idling truck at 1200...
but then again, I've only been ona boat a handful of times.

yes it does. alot. (fyi my redline is 4800 on my boat)..... but yes, idle speed its less likely but larger motors can cause more suction than a 4 banger....its just something that could happen not really gonna thouh im sure...
Don't turn the truck off, and try to limit the amount of time the axle is submerged. As long as the engine is running the vehicle will not stall, especially a V8.
In other words don't screw around on the boat ramp when launching or pulling out of the water, be ready to launch when you put in and be ready to pull when you put the boat on the trailer. Not only will all the other boaters thank you, but your truck will too.
Boat launch question.
