View Full Version : Leak from manifold?

05-20-2012, 09:46 AM
So notice the bilge was running a lot, and then realized theres a hole in the riser? It looks like a nipple, theres a few on the riser, but this is the only one streaming water out. Time to replace riser?

If it's a "nipple" leaking, then i would replace that part, new risers are less than 150...

where can i find risers for 2006 mcx

i was gonna plug the hole with JB weld, since we had planned on riding today, temps remained at 160 all day yesterday while riding before we realize what was happening. Is this a good idea/

is yours equipped with the 1 piece ETX exhaust? If so, I think the nipple you are referring to is a forging / extruding plug. I think you can order new plugs from Indmar and have them welded in. The ETX exhaust is pretty expensive to replace.

I think it is the ETX, here are some pictures

boat is a 2006 Mastercraft X1 with 350 MCX motor

yes, those are the aluminum ETX exhaust. You can get the plug disks from indmar. There have been posts on here before with it being done. Just have to find a decent aluminum welder...should be pretty affordable. Buying new ETX exhaust is not affordable.

Same thing is starting in on the 04 - 209.
I think this is total BS.

mine is doing the same thing, I was told I need to replace them. If it leaking from the outside it may start leaking on the inside and get water in the engine. I thought about JB weld to hold me over until i can get some replacements.

I will start another tread with all my questions

04-209 start of 2nd season.
They must be paper thin.
Hate to even touch it, and other spots are doing the same.

In recent search - found where it was suggested to drain manifolds each time out.
Maybe it's true.
