Hi and welcome.

Heads were supplied by different vendors and may not be the same on all Mark II boats.

What brand of head do you have?

We've found that the more specific you can be in the question the higher degree of probability of a useful answer.   :D

AMA :  What model head?? 
 It should be a straight FWD easy replacement.  Just be careful if it's a Jabco, that when you screw into the base that the base is PLASTIC and you only get one shot before you can mess up the threads with the stainless screws.
What I always do when screwing into plastic with old threads, is to put the screw in by hand and turn it counter clockwise till you feel that it has engaged the existing thread.  Then you can use a screwdriver!!

Welcome Amari,
Iíve removed and reinstalled my Jabsco pump several times. It is very straight forward.  I would pump four or five strokes of clean water through the pump then turn off the seacock. Loosen the inlet hose clamp and the hose to the bowl. Expect some clean water to come out of each hose. Unscrew the joker valve clamp and those at the base of the pump and you should be all set. Ron is right about ensuring threads are lined up correctly before tightening the screws. Seals are simple and are designed so they canít be installed incorrectly. Generally itís the seals and joker valve that need attention. The pump structure rarely fails. Jabsco has a very good website providing useful instructions. I suspect Raritan and Groco have similar good instructions.
Iíve always found it is not too tough a job and is far cleaner than you may think although having a bucket and some paper towels handy is a good idea.

Be very careful not to overtighten the screws. Easy to strip out.
