How to change the oil in a Universal 21hp?

Hi, everyone. Now that I'm getting settled in to my recently purchased boat, I need to change the engine oil and filter. I've searched through the forum (and the manuals on the boat), but can't find anything on it yet:

How do I change the oil in my Universal 21hp diesel? What are the tricks and got'chas?

There are a number of manual and electric pumps available form any marine outlet for removing oil. I'd recommend an electric, makes the job much easier and you'll have it if you need to get other stuff out of tanks or whatever. I usually change the oil 2 or 3 times a season so mine comes in very handy. Just be careful if you get an electric because they can be top-heavy and fall over if your not careful.

Run the engine until the oil is warm... stick the pump tube down the dipstick hole and pump out all the old stuff. Move the tube around to get as much out of the pan aas you can.

You'll probably need a filter wrench for the filter. I have one that looks like a big wrench.... I find that works better than the kind you have to wrap around the filter as there is a lack of room / access. Change the filter as you would on a car.

Get plenty of those oil absorbant sheets from West Marine or a car parts place. Put them under the engine and over and under anything around the filter. (It doesn't hurt to wrap one of those sheets with wire ties and fasten it in your bilge to absorb any oil type products that might drip into your bilge too.... I leave one in mine all the time).

Get a funnel to pour the new oil into the engine.

All in all, not a bad job but as always on a boat, can get messy because of the lack of room to move around.

Good luck!

Excellent!

FYI, to others: The link contains the full engine manuals, both operation manual and service manual.

Thanks, guys.

The closest Westerbeke dealer is 30 miles away and charges from the time the tech leaves his shop untill he returns which is almost two hours total travel time. The bill would come to $70 per hour for abour 3 hours including the travel time plus the cost of the oil and filter. Total about $225-245.

My neighbor, who has a twin screw power boat with difficult to reach filters pays almost $1,000 for an oil, filter and fuel filter change.

Like most frugal sailboaters I change my oil myself. The only cost is the price of the oil and a filter. By belonging to the C36 association where you can ask around for making minor maintenance suggestions a sailboater can save many times over the cost of membership and meet some nice people in the process.

Be sure to have a DRY BILGE!! used oil from a diesel is very nasty, fantastic or super clean will clean it up if you hurry. I hate a nasty bilge so I prepare well and have plenty of oil absorbing mats, rags and I put whatever I pump (electric) the oil into in a large flat plastic storage box so any spills are controled. Have Fun, clean fuel and clean oil are the two biggest rules to diesels. Russ&Spanki:)
