Hi, I drained the leg oil from my 2 stroke 4ohp Mercury (4 cylinder) today, but not that much came out.
When I refilled it it only took about one tube of oil, I thought an engine like ths might take alot more??? Can anyone advise me of the capacity of a leg for these engines (roughly)

Cheers Bryan

Dunno the capacity, sorry.
But if you have carefully filled and She,s up to the level should be ok.
Run the motor for 2 ticks let Her stand and check the level again.
They dont hold a lot. I know that,s a bit vague! What I,m trying to say is Your reaction to the apparent stingy amount of oil is quite common, thought so myself first time I did one.
Did it thrice to make sure!!!

Oh! How much was the "Not much"?

Yep, if You look at an outboard, there aint much room for a big gearbox.
Also what does ot do?
Sends yer backwards and forwards.
Yer aint got 1st 2nd 3rd 4th 5th and all that there stuff.
Pretty tough pieces of kit too.
No clutch and lots of times reverse is required when the operator is in "Panic Mode One"! /forums/images/graemlins/grin.gif

Just about a tube full is correct.

as they say fill untill the oil comes out of the upper vent hole removed for the purpose..

Old oil definately without white streaks etc, other wise the seals need to be checked.
