Anyone have any thoughts about how to proceed to the next step? I am the proud new owner of a Westerbeke 40 powered sailboat. The motor is under water to the leval of the crank pulley and is not seized. I have been thinking about attempting to to try start it. I will change the oil first. Any other thoughts that i should do beforehand?

Depending on the clearance issues... What you may want to try and do is drain the oil, and while dry, put some kind of heater in there to point at the block. Be VERY careful about flammability issues. You may not be able to do this.

The idea is that if there's any moisture inside the engine, evaporate as much off/out as you can. Moisture can kill a diesel. If you can't do this, fill it with cheap oil (the cheapest possible, but still specified for your particular engine) to see if you can fire it up and get it running before spending any more on it. If it runs, then get it up to operating temp if at all possible. Make sure the cooling system is intact and functioning, etc. Once there, then you'll want to drain out that oil and replace it with the correct stuff.

I have friends that own an auto shop (Very reputable. family business that's been there for 30+ years now and the best shop in town), and they keep "blended" oil handy for initial starts on replacement engines, etc. This is basically all the oil that's left over in the plastic bottles from regular oil changes, etc. They have a drain setup they put them in upside down and it all drains the last of the oil left into gallon jugs to use for things just like this. You're not going to hurt an engine using this type of method, but it's not something you want to use for more than getting it running initially.

What you need to find out before spending any serious money on it is if it indeed runs before deciding if you want to spend any more cash on bringing it back.

Is there actually water in the crankcase? I have had water over the crank on an inboard and it did not get into the crankcase. The oil will float on water, pull the drain plug and check for water coming out , put the plug back in when oil starts coming out. Make sure the oil level is correct and start it up.

Leftover oil in a "replacement engine"? That doesn't ring as "best" to me. You do not know what could have gotten in that oil or what viscosity it is.:eek::mad:


If you can, drain and refill the crankcase with NEW, correct type, OIL and replace filter(s).

Disable the fuel system and crank the engine over until you get oil pressure. Once you get pressure, enable the fuel system and start the engine. Let it run up to operating temperature.

Check the oil, if it is NOT milky, leave it in there until you get an hour, or so, on it.

Then, drain and refill with new filters.

You may waste a bit of oil and a filter(s) but Westerbeke's aren't cheap.

What DJ said, plus, if it was me, I would probably pull the motor and change the bearings. i know it is most likely overkill, but I like to know what I have in the lower end. By pulling it, and gage the bearings, I know that it is or isn't in good condition. And since I have the motor out, change the bearings, and crank seals.

If you do not want to pull the motor, (I don't blame you) you can follow the wonderful advice that you have recieved from DJ.

Sorry if I wasn't clear. It's not leftover USED oil, it's NEW oil. The residue from the plastic bottle after the majority is dumped in for a normal oil change. It's just several different viscosity ratings, but all quality stuff. and WAY better than the bulk oil you'll usually get at the discount oil change shops. 100% safe to use as starting/break-in oil. They've been using this method for 20+ years with zero ill-effects at all. It's just used on old engines that may not have been run in a long time to get them up to temp, suspend any contaminants that were in the crankcase into the oil, then drained out when warm to remove as much crud as possible. Then it's filled with the proper/correct oil.

I also applaud them for NOT sending that oil to the landfill like most everyone else does.

Additionally, the method for priming the oil system posted by DJ would be highly advisable as well if this motor has not been run in a long time.

That's exactly what I would do.

Yeah. I applaud my neighbors for bringing their used oil to ME so I can pour it in my storage tank (right below my waste oil furnace!!
