Sounds like a bit of contamination but if its cold... gear oil is quite thick

As Nos said .. marine grade EPX 80/90's contains stuff to stop water affecting the gear surfaces even after slight ingress

edit .. do the change .. then check it after a month or so and see if its discoloured again, because you might have a failed seal on the output shaft thats letting water in, either that or you have impending gear failure

mark did you watch the video in the link above? that engine has 3 holes (drain, vent and fill) as opposed to filling through the drain hole. Is that what you are referring to?

its not white grey or yellow its quite black, looks like it aint been changed in ages, its a second hand engine so i thought a service might be in order before i used it on water, i did hear it running before i bought it, it started first pull ticked over evenly and pumped plenty of water, did not find any metallic grey trace in the oil or signs of water, just looks like it needed new oil, i am going to fill it with ordinary ep 90 , i am skint after building the trailer to take the boat and our local chandler does not keep marine ep90, but i will just run it for a few hours as a kind of flushing oil and then change it for proper stuff,
thanks for the help chaps.

i watched the video but i didnt get any sound, did you? the third plug i was referring to is directly above the water intake so i assumed the previous reply of it being a flushing point to be correct ? i have drained it from the drain plug and refilled through the fill plug? the mrs went in the shed to get the dogfood out tonight, smelled the ep90 which was all over the place and promptly accused me of leaving some eggy farts in the shed
its my shed and ill fart if i want to.

that sounds right then - some engines (like the one in the video) have 2 plugs at the top of the gearbox to make life easier.

did you fill it from the top? you are supposed to fill from the bottom (unless like the video you have 3 screws in total). because its fairly "glupy" you may have air trapped at the bottom of the gearbox. I would be tempted to turnover the gearbox a bit (with kill cord removed and in neutral) and recheck level (and top up if necessary from bottom).

Goood .. no water contamination then .. black was the only colour I didnt mention .. what that means is the oil hasnt been changed in ages but your seals are good

the smell is a sulphide smell like gas.. which is the oil breaking down .. and you got it at a time before it becomes useless to lubricate the gears .. all good

It's only an extra 5 to buy a litre of Quicksilver gear oil over the price of EP80/90.

Have a look on the tip of the drain plug-it's a magnet and any metallic particles will stick to it very well.

yes filled it from the top, i did note pete7 said fill from the bottom but i thought i would fill from the top leave overnight wobble the engine around a bit to move any air and then recheck the level, these marine engines are very different to anything else, i built this a couple of years ago http://img.villagephotos.com/p/2004-...8/P1010004.JPG
its a westfield with a 3.5 sd1 vitesse motor, sounds like gods personal tvr, 8-1-2 exhaust
holley carb, i am not a total mechanical numptie but marine engines are a different kettle of fish altogether and i am very grateful for all the advice i have had from you chaps

i did look at the tip of the drain plug when i took it out i thought it might be magnetic and it was free of particles of any sort, i know marine ep90 aint all that expensive (but our local chandlers cater mostly for canal boats when i went to buy marine 2 stroke oil i looked for gear oil and could not find any so i thought i would use the ep90 i have as flushing oil and pick up some proper stuff when i can) surely a few hours on ordinary ep90 and then a drain and refill with marine grade cant do any harm can it?

Should be OK-I'd leave it for a while to drain though when you do the change just to get rid of all the EP90.
