no water coming out of the exhaust-gctid378399

[Guest]

on my 84 Bayliner Contestsa I flushed both the outlive (volvo)and exhaust hooked up the muffs started the engines but no water came out of the exhaust. Any ideas.

On the Volvo drive, there is a large hole on the rear bottom of the outdrive. That hole must be plugged for the seawater pump to pick up the water. I use a piece of duct tape. Also, I have found the water pressure to the boat MUST be turned on high to help force water up the drive to the seawater pump. The Volvo drive does not have the impeller in the lower part of the drive like Mercs.Also, once water starts flowing, I also see that I must have the engine running about 1200 or so to keep the coolong water flowing.

Ditto Tony on plugging the drain hole...., and check/replace the water neck fitting.

These are a wear item and require routine replacement.



Any breach in the suction side will prevent the sea water pump from pulling water up/in.

In your completed projects thread, I mentioned; See the BOC Vault thread titled Volvo Penta AQ series frequent Q's & A's for any V/P drive related help.

Go to local hardware store get a tapered rubber plug- pushes in and doesn't care if it is wet - I fought getting things dry enough for tape to stick enough times that I gave up on tape. the plug fits perfectly into the fitting that the hose fits on the flushing unit.

You may laugh at this... but my plug for these is made from Tremco Vulkem 116 Polyurethane Sealant.

I filled the neck portion of a plastic funnel with Vulkem, let is cure, pulled it out..... and "voilà" ... ya got a near perfect plug that doesn't care if the drive is wet or dry.

I put a lanyard on it so I won't loose it.

You may not be entirely out of woods here!

How long did your engine run while you were figuring out that no water was coming from the exhaust?

An impeller can be ruined in as little as 20 seconds if run dry.

I'd remove it, and take a look at it.

Re-install with glycerin on it.

I really like this idea.

I have been using those little expanding plugs (7/16 inch), stick it in and flip the little lever making it tight. This is just a bypass, incase the intakes get plugged by debri, you have a safety valve to continue sucking water.
