Wasps in Exhaust

How would y'all go about getting rid of a wasp nest in the exhaust of your diesel?

If the exhaust is mostly blocked, I would be very hesitant to run the engine at all: If the raw water seacock is open and you are pumping water you will quickly fill up your wet muffler and exhasut, and upon shutting the engine down you risk backfilling the cylinders thru the exhaust manifold.

On the other hand, a quick start and full throttle might blow them right out. An interesting question for sure....

Well, it looks pretty blocked...

Well, if you can see the nest... Is the nest active? If so, I might try shooting it with wasp-killer, then pulling as much out as you can with a tool. I think if you can get most of it out, then you could probably run the engine and blow the rest of it out with the exhaust.

Any other opinions on this one?

It's Awaaay back in there, and it is active...the broker was stung just the other day, in fact. I'm not sure how far back it goes into the exhaust line, so I'm concerned spraying it with wasp killer might not do the job.

Next question: have you closed on this boat yet? If not, you could insist the broker and seller take care of it...

What is the configuration of the exhaust? Hose? How about removing the entire length of hose to clean it out (or to simply throw away and replace)? Probably a pain, but sometimes it's the only way. Given what you've said so far, that would probably be the safest bet. But I'd spray the Raid in there first to kill whatever you can, for your own safety during removal.

Brake cleaner is an effective wasp-nest shooter, if you happen to have some lying around.

Also WD-40 works wonders, kills them instantly.

Just to tie up loose ends... :-)

We closed on the boat yesterday, it is currently 37 degrees outside, the engine is pretty much toast and I started prepping it for removal two days ago. My reciprocating saw made short work of the exhaust hose.

Case Closed!
