    So the head shit the bed the other day. Its raritan thats only a season and a half old. Been sounding a little queer for the past month.

    Found all this build up either side of the motor housing. Any thoughts what causing this; perhaps improperly sealed at the factory? 20181117_132212.jpg

    In what sense? How much preventitive maintenance is there on a supposedly sealed electric motor?

    As far as appearance yes I could take apart the fairings each trip and scrub down the entire unit, but a heavy dosing of bleach keeps the odor down till the choker valve get replaced mid season.

    A thorough cleaning once in awhile will keep the odor down even better, and the head will not wind up looking like that after such a short time in service.

    It gets a lot of use, 15-25 trips a month in season with 10-15 guys, most enjoying a few (to a lot) of adult beverages

    Then it should be cleaned every day.

    What kind of beer are they drinking :) Guinness or Coors light?
    So did the motor fail? Maybe this is a boat system electrical issue? I would check other electrical components on the boat for accelerated corrosion. New marina? New next door neighbor? How's the prop zinc look? Is the ground connected to the main ships ground or something else? Do you plug into shore power? The ground wire has a funky pinkish color which is often due to electrolysis. It doesn't look so much like pee splash corrosion (acidic) or excessive bleach corrosion (base) as much as electrical imbalance attacking the weakest links (lots of corrosion on the end caps of the motor but nothing on the main case.) Pee and bleach might do this after several years but after one year is unusual. Something is making this happen quicker than it should. What happened to the previous head?

    Is it a salt water head? To me it looks like seawater leaked down from that flange above the motor and attacked the aluminum motor end castings. One of my customers has an old Tiara with one fresh water vacuflush head and one Raritan salt water head in the guest cabin. Though the fresh water head gets a hundred times the use, it looks and works OK. The salt water head looks like a haunted house candle.

    I have the same head. Looks like flange of bowl base may be leaking as noted above. If not sure is nasty looking. Other thing I notice, mine only has two wires, plus and neg. Looks like you have two wires attached to neg terminal. Not sure what additional wire would be for.

    The second, (Yellow collar) wire on the negative terminal of the head motor is probably a grounding, (bonding) wire that should be on the motor body and NOT the negative terminal.

    I would look at where ground is connected and also ask-

    Are you feeding this with salt water? Maybe just salt water dripping all over it and sitting on the steel/white paint is all.

    With that amount of use i would say you got your monies worth, replace with a higher end or better protected model.

    When I got my boat in April the seller stated the forward head motor needed replacing. They aren't cheap. The motor buzzed but did not spin. It turned out it was a rusted bearing. $8 bucks and a couple of $20 cuss words later and we were back in business.

    Been using Raritan Marine Elegance head- full china bowl and motor is easily accessed. Kept up with my kids for 5 years now on 2 boats.

    We have Raritan Crown model which looks like OP's. They are 12V raw water heads that macerate. Seem very robust and powerful. Easy to replace/disassemble components. After having used only manual heads before I have become a believer.

    If that extra wire on the neg is for bonding as suggested above, why would there even be a need for bonding the head?

    Because it has electricity and salt water running through it. And parts made of various metals.
