I went budget this time
My friend had a Raritan on his old boat. It was old, old enough that when the seal on the pump went, and sea water squirted on your hand as you pumped, it was not an unreasonable amount of time for it to wear out. All head companies have rebuild kits readily available, which means they all wear out eventually. For me, it seemed to be a question of whether or not a more expensive head is worth it for the amount I use it. I decided to try the Jabsco cheapy, on sale for $119.99. So far so good. It works just as well as the Raritan (an old one anyway, I have never used a new Raritan) and if it lasts five years I will be happy. A new pump assembly is $109, so I should be OK for years and years (knock on wood) still having spent less. Unfortunately, only time will tell if I have made a mistake, the Raritan has always recieved high praises so you can't go wrong if you have the budget.
