Thanks guys.  Based on your knowledge I am now pretty certain that the existing 
bolts are hanger bolts bedded into fiberglass/plywood.  I will shop around here 
for SS versions of those and/or lag bolts.  Thanks Ed for the heads up on the 
seat lifting/opening.  I will make sure to check that before drilling.

My boat is 2.5 hrs drive from home and is in the middle of nowhere so if I get 
to it without the right hardware,  I am hooped.

Really helps having others provide advice so I can go back out with the right 
gear in my bag!

Subject: Re: Stus-List Mounting new head in 29-2 - bolt pattern mismatch

Bruce:

I recently replaced the original head on my 1981 C&C 34. The original "bolts" 
were not bolts at all but were what I think are called hanger bolts - part 
screw and part bolt. The screw part was into the pan on which the head sits. 
The head was held down by cap nuts. Remove the head and back out the hanger 
bolts. I carefully measured for the base of the new head, drilled, and used SS 
lag bolts. The new head mounts firmly.

I did run into a placement problem. A wall of the head compartment was angled 
thus reducing the space directly behind the head. I had the new head bolted 
down and plumbed. When I put the toilet seat on, the angled wall prevented the 
seat from lifting/opening fully. Solved the problem by reversing the side of 
the pump relative to the bowl but had to re-drill for the lag bolts. Good luck.

Hello.


I pulled the existing Brydon head from my 29-2 and am installing a new Jabsco.  
  The existing bolts appear to be bedded into the fiberglass pan that the head 
sits on and of course the bolt pattern for the new head does not match these.  
There is no access to the underside of the pan.  Any ideas I've come up with 
for creating new mounts depend on knowing the thickness of the pan.

Any 29-2 owners know how thick the glass is on the pan - is it solid?

Any 29-2 owners encounter this issue and have a solution?

I could use stainless steel toggle anchor bolts that would work if the pan is 
hollow - thinking this would be easiest.

I could cut the heads off of bolts and bed them inverted (with resin/adhesive) 
in new holes if the pan is solid.
