Marine Heads Footprint

Do jabsco, Par and Raritan marine heads, (bowls) have the same foot print?
Will the 4 bolt holes line up?

From what I can tell from the user manuals, not even close. The manuals are available on-line and have line diagrams with full dimensions.

I know the Wilcox Crittenden and Raritan do not. But, most/all heads are ona raised fiberglass area so putting in new holes is not a big problem. At least we found that part of changing heads easy, the hard part was bending the existing intractable hose to fit the new output.

Are you asking if the bowls are interchangable between brands of if the toilets can be mounted in the same screw holes? The bowls with a water inlet on the back are usually interchangeable the bases probably not.
I'm not sure about the Raritan SeaEra. It was designed to be an improvement over the Jabsco electric toilet and they may have made the mounting holes the same. I know the SeaEra can use the same bowl as the Jabsco. What are you trying to do?

All BOWLS that have a 4-bolt mounting pattern will fit ANY toilet base...as shown in this ad on the sailboatowners.com site for the Raritan PHII/PHC "conversion:" sbo.com PHII PHC LBA

However, the mounting bolt pattern for any new toilet BASE never matches the mounting bolt pattern in the sole (floor) for any other make...and sometimes new ones of the same make/model longer match the mounting bolt holes for older versions of the same toilet.

So if you're asking whether your existing bowl will a new base, the answer is year. But if you're asking whether a new toilet will line up with your existing toilet's mounting bolt holes in the floor, the answer is no...with one notable exception:

The Raritan SeaEra Raritan Sea Era was purposely designed to be a "plug and play" identical upgrade/replacement for the Jabsco 370xxx series electric toilets, even down to matching the mounting bolt holes. An even simpler, less expensive solution, though, is a SeaEra "conversion," which lets you recycle your existing bowl, seat and lid (your bowl WILL fit).

However, it's not a big deal to drill a few new holes in the head sole and fill a couple holes with expoxy. Touch up the ones that aren't covered by the new toilet with a little nail polish or, a bung if you have a teak sole.

Maybe I should explain what I am trying to do. I have a Raritan PH II pump
and base. I need a bowl that will fit. the Raritan base. I know I can fill in the old holes in the head sole (floor) and drill new holes for the Raritan base that is no problem. The problem is getting a bowl to fit the 4 hole pattern on the base. Is that better? Do i make myself clear?

Aha! You'll be glad to know that ANY marine toilet bowl that has a 4 bolt mounting pattern will fit your Raritan base.

The only thing that might cause a problem is an upgrade from the smaller "standard" bowl to the larger "highboy" or "household" size. The larger size will fit the base, but half the increased fore-aft measurement is forward of the hole in the middle and half is aft of the hole...which means the larger bowl needs more room behind it. So if you are upgrading to the larger bowl, make sure you have enough space behind the base. However if the new bowl will be same size as the previous one, you can disregard this entire paragraph.

Thank you Peggie Hall, I thought that was the case but I was not sure.

RM69 and Jabsco (old) do not.

Peggy, Thanks for the info on the SeaEra mounting holes. It makes sense that they would be the same. Raritan wants to sell SeaEra conversion kits to Jabsco owners.
