Adventure yesterday bringing her back from the yard (new bottom paint).
Doing 6.1kts at 2100rpm.
Lost power suddenly.
But the engine re-started, revved fine in neutral; then stalled in fwd.
So killed it and sailed home.
On inspection found this (see pictures - pic2 is contrast enhanced so easier to see the failure):
- pipe at the top comes from the engine exhaust manifold.
- hose in the upper left goes to an outside vent.
- hose coupled below goes to a water lift muffler.
You can see that the Y pipe has come loose at the top.
The failure was pretty messy.
Light grey smoke from the lazarette - I assume exhaust escaping from the break
Water - fresh not mixed with oil or gas - dripping from everywhere in the engine area. I assume from the muffler absent exhaust pressure to push it out the tailpipe.
So now what ? I'm thinking the coupler threads rusted out (its 12 years old) and it should be replaced.
Hoping the top pipe threaded female side is ok.
Anyone know who makes one ?
1 1/2 inch OD. The vent leg is 7/8" OD.
This is all new to me. Any advice is very welcome.
