Default Oil and filters

I am going to be helping a friend this weekend change the oil in his boat and get it winterized. He has a 1993 Cig with twin 525SC's. Can someone tell me how many quarts of oil these engines hold and would anyone know the part number for K&N oil filters on these engines also? I appreciate all the help.

They hold the same as a magnum engine-8 qts is capacity with filter when empty and use the same oil filters. The most my 525SC's ever took was about 7 quarts at an oil change. Top it off with the boat in the water after the filter is full and the attitude of the boat is correct.
Use a Mobil 1 Filter #M1-302 and 15-50 Mobil 1 synthetic. The best price for the oil is at Walmart in 5 qt jugs and they usually have plenty on hand at the Osage Beach store.
