Oil Pump Out

[Budsparks]

Does anyone have a source for the Crankcase Oil Pump that Cummins lists in the owner's manual (Part number 91-90265A-S) that attaches to the end of the hose attached to the oil sump.

We don't, and can you share what you find, just in case it is needed in the future?

Thanks, Don

You might want to give the Cummins/Mercruiser Distributor in Kenly, NC a call. I purchased a QSD 2.0 Shop Manual and some filters from them a while back and found them to be very easy people to do business with over the telephone.

Ken,

Did you find that the Cummins QSD 2.0 shop manual was a match for our Mercury version? We have a 2009 R-25 with the Cummins 150.

I have been wondering how to drain the closed coolant. We can't get access to the drain plug on the port side behind the water separating fuel filter and then behind that, behind a couple more metal rods. Have you had any luck draining the coolant?

We found an online PDF of the Cummins repair service manual but am looking for more detail.

Thanks for any insight, Don

A method I use which allows removal of 100% of the oil works great on my engine (older pre-2008 Yanmar engine). An alternative I use is to use one of the cheap pumps to pump out about 75% of the oil while warm then I open a FUMOTA type brass valve I installed on the oil pan drain (after that oil cools). I have used these valves for years on road vehicles and they are in heavy use in fleet/commercial applications. I do not know of any leaks or failures due to their use. The drain valve I have allows a flexible tube to be temporarily attached to route the oil back to a container in the bilge. With only about 25% of the oil still in the engine it is easier to catch the remaining oil in a smaller container held low in the bilge. You get no oil in the bilge. That is on any future oil changes. Since the plug must be removed the 1st time to install the drain valve that 1st time does involve dumping the 25% or so remaining oil into the bilge. As such it is best done when boat is on trailor at home. Futher changes can be done with boat in water.

Clearance between my drain valve and fiberglass hull is about 2 inches which should prevent any contact during engine operation. I do not know how well the drain will fit on other engine designs. I do not have the model number for the valve but you have to buy the one wioth the drain nipple and the optional adapter extension. Total cost is about $30.

I could not figure out a way to put a large enough container in the bilge to allow draining the entire engine oil sump so it is still necessary to pump out most of the oil.

+1on the Fumota valves. I use them on all of my cars, and they turn oil changes into a 10 minute no-mess affair. Worth every penny.

Here is some info on the Fumoto Valves http://www.fumotousa.com/ The valve looks cool.

I could not find anything on the Cummins part number on Google. That was a real surprise to me. In fact, when I googled the part number, I only got one link related to Cummins. All the other links went to mostly strange medical/scientific stuff.

Don,

The Cummins/Mercruiser QSD 2.0 Shop Manual covers both the inboard (used in the R-25) and the sterndrive versions of the 150 hp QSD 2.0 engine. The only divergence I have noticed between the shop manual and the engine installed in my boat (also a 2009) is the placement of the secondary fuel filter. The shop manual shows it mounted on the port side of the engine while in my boat it is mounted on the starboard bulkhead near the front of the engine.

Have not attempted to drain the engine coolant yet. It is on my spring "to do" list before I put my boat back in the water.
