Holding tank wrench

[peterbrown77]

Hola -

Is there a specific wrench to remove the access port? Or just whatever works?

TIA

There should be threaded port caps called "Deck Plates" which are for fuel filling, water filling and holding tank pumpout.

You need a "Deck Plate Key" to open them. They are found at any ship chandler.

I believe the OP meant the large "access plate" at the tank, not the deck plate at the deck level.

To OP: A picture of the plate in question would be helpful.

This is the picture he has had trouble uploading:

Interesting. Never seen a plate like that. Not that I'm any kind of expert on holding tanks but having 5 boats not one had any such plate on any tanks. One could probably DIY a simple wooden cross from scrap 1X4 or some such.

They are threaded and need to be unscrewed. They are typical in Beneteaus at least. I use a 4" 1x4 that has been rounded off on the corners, then slip joint pliers to turn. I've heard others taking the handle of slip joint pliers to put in opposite sides, then another wrench to turn. I have also seen photos of a device that people have made to fit the cross pattern that also has a handle for leverage. They do unscrew but sometimes the O-ring has a lot of "gunk" seizing it in place.

Yes… what hlev says. There isn’t a specific tool. But use a large pair of pliers to put the handles in the slot and you can then turn by inserting a screwdriver between the two handles. Normally, nothing more than fingers are required to turn if the o-ring is lubricated with silicone grease.

Thanks everyone and yeah, I kept trying to upload the photo to no success. Beneteaus are lousy with that cap; both water tank, both holding tanks, and the fuel tank have them. I may 3D print a wrench just for kicks.
