Easy oil drain

islands50 · #1 (**permalink**) 10-10-2010

I have a Bristol 29.9 with a universal diesel model 20 (5416) and would like to replace the oil pan drain plug with a fitting that I could attach a hose to for an easier way to drain the oil. Pumping it out of the dipstick hole doesn't quite get it all. Does anyone know the size of the plug. I know it is not pipe threads and I think it is metric but I cannot find anything to fit.

My Universal M-12 came fitted with what appears to be a hose kit---rubber hose, plug, banjo fitting, washers and glands--- from Torresen Marine in Michigan.

A quick check of Torresen's Web site yields an aftermarket kit: Universal 200390 Ships Store TorresenThing is, your specific engine isn't listed for this particular kit.

Give 'em a call. They've been pretty helpful to me on other things in the past.

Consider buying a Reverso oil change pump as well. Pump the old oil out; pump the new oil in and do it in minutes with no mess.

It looks like Torresen has a kit to fit my engine. Do I need a pump for this kit or can I just use gravity if the oil pan is above the end of the hose?

Any of the various vacuum pumps will speed things up - don't forget to warm the oil first.

i50, I have the same engine in my boat.. it has a hose on the bottom and it's not that much of a job with a little hand pump.. these engines don't hold allot of oil like car and truck engines.
