A 14 quart pan on a 420 is a complete waste of money. The stock pan will work just fine.

if your running the boat hard in the ruff stuff you want to keep the oil in the bottom of the pan and seven more qts is a good thing. also with a gil pan it has a scrapper bilt into the baffle which keeps oil from winding around the crank and helps with windage .especially if your running over 5500 rpms.but if your not hard core a 7 qt pans fine but still recomend a cooler.

My oil pan on 88 420's had the trap door ... I reused them and went with a 2 qt oil filter wix racing 51734r

My Merc 400's have the `14 qt pans. I think ANY high performnce offshore boat should have them.
