Cracked Exhaust

One of the exhaust manifolds cracked without anyone's knowledge until the floor got squishy. Got the boat back to the slip and on the hoist. I need to get it back on the trailer and to the shop for a permanent fix but does anyone have a suggestion for a temporary fix to keep the water out while idling from the slip to the trailer?

Row or tow. If you don't start the motor you won't have any water running through the exhaust.

if it's not too big, jb weld might help

Or duct tape, how fast is it filling? Surely you can't run that much water into the bilge between the lift and the ramp.

Our exhaust had a leak but it didn't really fill that fast. A couple of inches in the bilge over a couple of hours at most.

The plan is for a tow, but with the exhaust being below the waterline it is filling rather quickly. I'm just looking for a temporary patch like the JB Weld idea. Obviously several ballast pumps will be on hand.

If you are towing it, remove the flex hose between mufflers and manifold, and cap the muffler.

Even just stuffing a rag or something in the exhaust will slow the entry of water if you are towing. If you want the shop to repair the muffler that is in there, sometimes doable, then I wouldn't jbweld it, that will make them more than likely only look at replacing it.

duct tape your flap down. You could even silicone it then just peel it off when you get it off the water.

X2 on the JB Weld. Get enough in the crack and you might be able to delay the repair until after the riding season. I've seen JB weld like stuff used to fill in erosion on large diesel engine blocks.

Does jb weld fiberglass/plastic?

Get an inflatable plumbing block from the hardware store (or just use an inflatable ball). Stick it in the exhaust and fill it up with air. You might even be able to find a kids toy ball that fits snugly enough in the exhausts to block the water intrusion.
