The Mercruiser part number is: Quicksilver 14957 , crossed over to Baldwin is: B360. A Baldwin B27 is a longer version that will work if you have room. According to Mercury, here is the recommendations for oil:

Engine Oil

For optimum engine performance and maximum protection, use the following oil:
Application Recommended Oil
All MerCruiser engines Mercury MerCruiser Full-Synthetic Engine Oil, 20W-40, NMMC FC-W rated

IMPORTANT: Lubrication requirements for catalyzed engines differ from the requirements for non-catalyzed engines. Some marine-grade lubricants contain high levels of phosphorus, which can damage the catalyst system on MerCruiser engines. Although these high-phosphorus lubricants may allow acceptable engine performance, exposure over time will damage the catalyst. Catalysts damaged by lubricants containing high levels of phosphorus may not be covered by the MerCruiser Limited Warranty.

If Mercury MerCruiser Full-Synthetic, 20W-40 oils is unavailable, use the following lubricants, listed in order of recommendation. If you are servicing a catalyst engine, use these for short periods of time only.

Mercury/Quicksilver 25W-40 Synthetic Blend, NMMA FC-W-rated 4-cycle MerCruiser oil
Mercury/Quicksilver 25W-40, NMMA FC-W-rated 4-cycle MerCruiser oil
Other recognized brands of NMMA FC-W-rated 4-cycle oils
A good-grade, straight-weight detergent automotive oil according to the last row of the operating chart below.

NOTE: We do not recommend non-detergent oils, multi-viscosity oils (other than as specified), non-FC-W-rated synthetic oils, low-quality oils, or oils that contain solid additives.

This crankcase oil recommendation supersedes all previously printed crankcase oil recommendations for MerCruiser gasoline engines. The reason for this change is to include the newer engine oils that are now available in the

Re: Which oil filter & oil?

If you go to Fram.com, they have a cross reference chart for all oil filters. You can probably find dozens of filter numbers, some of which are available at your local auto parts store for less $ than at a Mercury dealership.

And as far as motor oil on an inboard outboard: You can use your favorite brand of regular car/truck oil. If it's a newer engine with the catalytic converter, just don't use diesel oil. I personally believe Mobil One is better oil than anything being sold by Mercury.

When there is any question on motor oil or lubrication, see BobIsTheOilGuy.com.

Re: Which oil filter & oil?

Everybody's got an opinion on this one I'm sure, but I'll throw my preference in fer ya anyways. I like to use the long AC Delco filter. They make a very good quality filter. The number is PF1218 and auto parts stores around here sell 'em for about $4. I've been using some old 40w old I've had sitting around for a long while, but now that I'm out, I'll be switching to 15w40 diesel oil this summer. I'll find whatever is on sale. Probably Shell Rotella or Chevron Delo. It has a higher zinc content that is better fer yer motor. The 20w40 is something that was made up for recreational equipment. It seems and its purpose is to drain your wallet do I believe. Happy Boating whatever ya do my good sir!
