[Ray 911s]

Every MerCruiser engine has a drain plug in the oil pan. In some cases on product before the mid to late 90's, the dipstick tube extraction method is the only way to get oil out due to room in the engine compartment. This is dictated by boat design - some have very deep compartments and stringer set ups and boat design requires a low CG. In those cases the oil pan sits nearly on the floor of the compartment.

Since then there is a banjo type fitting on the drain plug with a hose that attaches at the rear of the boat in the boat drain plug where the consumer can pull the hose out the drain plug, remove the cap and drain the oil. This would eliminate the method of the pump and small hose going down the dipstick tube.

The boater may be able to add this system, depending on his model and set up, but to do so may require the removal or partial removal of his engine to install the newer system depending on access in his particular bilge. Without serial numbers not sure what we are dealing with but we offer two kits, one is 865277A02 which covers 1995 and older units on V-6's and the other is 865278A02 which covers 1997 and newer V-6 engines.

These are both in the Mercury accessories book page 148.
