Head problems - Sealander # 752

[Bob Pullen HC-33 1981]

Hello to allI'm having a problem with the head.I have a Sealander Model 752 manual marine toilet, and recently have noticed that a small amount of liquid is coming out of the unit when it is pumped, right at the base of the pump handle shaft. I have detected an odor and have stopped using it for sanitary reasons. When I look at the exploded technical drawing of the unit, the most intuitive approach would be to change the O-ring (item #20). Would appreciate anyone's assistance, ideas, comments, etc. Can anyone suggest how to best find a replacement O-ring, or the process to take it apart, replace it, and put it back together.Many thanks.Bob PullenS/V Seanorita

It's time for a new toilet

Marine toilets, like most other things, do not last forever. The Sealand 751/752--which had a life expectancy of 7-9 years, btw--was discontinued nearly 20 years ago...no part have been available for it for more than 10 years. That o-ring isn't the only thing that has disintegrated...all the other rubber parts it have too...and the pump cyliner is so worn, scratched and scored by now that even if it weren't leaking, it's working at less than half its original efficiency. So it's more than earned its keep and way past time to replace it.All marine toilets are NOT created equal either...like most things, you do get what you pay for. Your best choice would be a Raritan PH II...or PHC (same pump, but on a compact base and with a shorter handle to fit in a tighter space. It's not the least expensive (and FAR from the most expensive), but well worth the price.

I must disagree Peggy

A friend has the original head in his 1926 powerboat made of bronze and wood and still works great to this day! The thing is beautiful.Otherwise I agree. The PHII is the best bang for your buck and can be rebuilt. I did mine last year and it works great.Tim R.

Ok, there ARE marine toilets that last forever

In today's dollars adjusted for inflation, the one on your friend's cost about $1000 then, $1800-$3500 now....just a wee bit more than most people want to spend to replace a worn out plastic compact. Your friend's 1926 boat wouldn't be a Trumpy, would it?

Thanks for the great advice!

Thank you very much Peggy.I appreciate your insight. I will try to find one that might be a close fit to the available space in the original head layout on the 1981 Hunter 33 Cherubini.Appreciate your suggestions very much.all the bestBob

Sam, it should be rebuilt every 5-6 years

as PREVENTIVE maintenance. Waiting till it shows signs of needing it is like waiting till the engine starts smoking to change the oil.
