Hi,
I changed the outdrive gear oil today and then set about changing the engine oil. I ran the engine for about 10 minutes and then opened the hatch and noticed that the bilge looked black. I hadn't used the boat for a while so figured that perhaps a bit of oil had dripped. However upon closer inspection, it was all oil in the bilge - extremely viscous and not mixed with water. The boat is dry stored and typically when I have it packed away, the bilge is dry.
I used a canister to extract approximately 3 liters of oil and I'd guess there's another 3 liters of black oil in the bilge. I changed the oil filter and the filter was full of oil - no leaks in the filter. There is no oil running from the top of the engine or the front of the engine so I'm really perplexed.
I've only ever extracted oil using a canister - so that leads me to wonder if perhaps the problem lies in the sump. I assume that if the sump plug (does it have one??) let go, then I'd have extracted very little oil from the sump into the canister which isn't the case.
So my question is; what sort of thing can have gone wrong? There is no 'wreckage' of sump in the bilge and the oil pressure looks fine.
Hoping someone can help as I'm well out of ideas - I'm also assuming that the outdrive is a sealed unit and that if oil had leaked from the outdrive, it would have been 'new' oil and not the old oil.
