502 uses alot of oil. Normal?
I have a 502 mpi mag. It seems like it doesnt matter if i drive it hard or not it uses oil BUT i notice it more when the water is really rough vs smooth water. Its not uncommon for me to go through a qt to qt and a half in a weekend. I do boat alot but is this normal? Thanks for all your help guys!

it is a function of the ultra light ring tensions they used to make power. if it annoys you you can replace them with the set that total seal makes specifically for that motor that fixes the problem completely.

When i bought the boat in March the guy had been using Castrol 20-50 so i continued using the same oil. This past weekend i put 7 hrs on it and it used a quart and a half?????

Mobile 1 15w-50 pretty much solved my 502 oil consumption problems. I still keep a couple extra qts in the boat but hardly ever have to top off between oil changes any more.
I use either Mobile 1 or K&N oil filters (large ones)

Your 502 mpi oil consumption sounds about on par with mine. After a couple good weekends of boating Im about 1qt low.
