This gasket set worked perfectly for my Mercruiser 170 engine. Make sure you get all of the old gasket off the cover and the block. It's also best to replace the oil pan gasket at the same time (as removing the front cover will likely destroy the front part of the oil pan gasket.)

Would have been perfect if they hadn't bent the package and creased the gaskets
