agree. it seems the yanmar folks just want to make life tough for those who might want to change the oil. i could easily get a shallow pan under mine

Is this an environmental regulation for marine engine manufacturers?
So we aren't discarding our oil to the bilge?

Re: Painting Marine Engines

Thank you. I nearly have my generator done as far as paint work goes.picked up my oil pan gasket yesterday.Here's a couple of pics.Not bad for a 30 year old motor? Still need to rewire everything.

Re: Painting Marine Engines

My 3GM30F has an oil change pump connected to the bottom of the oilpan. I always that it had a plug. I guess it must have been tapped or welded somehow. But it sure works great.. now for that paint job!

Re: Painting Marine Engines

Ive taken to painting the copper and aluminum with clearcoat. I kept finding a coating of aluminum oxide between the paint and aluminum when stripping and figured there was some kind of reaction between the pigment in the paint and aluminum. Doesnt happen with the clear.

Re: Painting Marine Engines

Oxidation does happen unless you use acid etch primer first.Then sealer and then the color coat. Clear coating lots of different bare metals is okay.But it will last a very long time if you use a polyurethane.
