RE: Guys, help me out - oil pan full of seawater!

Over here oil companies add kerosene to road diesel during winter time to keep the diesel from turning to gel as temperatures drop below minus 10 degrees Celsius

I have seen that done during the winter in Alaska as well, I wondered what the effect on the engines longevity might be. *But I doubt they really care, they're just happy to have a running engine at those -30 F. degree temperatures.**

Back in the 70's we also had No. 1 diesel here, a lighter grade and I don't see that anymore. I heard it was still available in the far north.

While fueling, my son accidentally grabbed the gasoline nozzle and pumped 2 gallons in one of our fuel tanks before I could stop him. ***We closed the valves, isolating that tank and called the Perkins people. *They said two gallon of gas mixed in with 125 gallons of No. 2 was no problem. *Just keep it isolated for a day or so of cruising to ensure it mixed well.*

Both gasoline and kerosene are used to keep the fuel from gelling in low temps.

Under 10% is frequently acceptable .

Both kero and gas are poorer injector lubricants than diesel, so a gallon of cheap 2 stroke outboard oil is frequently added with the kero.

RE: Guys, help me out - oil pan full of seawater!

Kevin, a question. Was the boat on a single anchor, or was she moored bow & stern.

I am amazed that there would be enough pressure exerted through*the exhaust tunnel to push sea water through the exhaust water locker, with its baffles, then up*through the elbow and* down*past the cylinders to the sump. I assume this is what happened or am I missing something?

Second question, are there any downsides on fitting one way SS flaps to the wet exhaust under the transom?

AS noted they don't work in hard conditions.

A cable operated valve would be grand , but not cheap to install.


"Best" would be a higher gooseneck in the exhaust manifold , seamless.

http://boatdiesel.com/Articles/Artic...ion.cfm&Y=2007

Or directly to Seaboard Marine site:
http://www.sbmar.com/main/articles/category/ and find Tony's article.

I'd also suggest you look up and read the above articles from Boatdiesel and/or Seaboard Marine about exhaust systems. Yours may be extreme and the result of the storm only but read it and study and decide. In the future an expandable plug as suggested may be all that is needed for storm protection if your exhasut sytem is ok for normal use and protection.

Since the last post was a long time ago I assume you to be on the way out of the woods. Several oil and filter changes are in order along with runups to temp to dry it out.
