Lrg Fiberglass exhaust bellow under cockpit question

How difficult was it to remove the fish boxes? The ones on my 35 Cabo were easy to remove, however the ones on the 40 are installed differently.

Thanks for the lessens learned regarding the 40 with the prop pockets. I can see the (4) little screws in each corner and all the caulk. Razor duty and patience and I will get them out. As mentioned,I did the same on my 35 Cabo express which gave me full access to the exhaust line and strut fasteners. I also replaced the fish box gaskets while I had them out.

It sounds like after all the caulk is removed, and macerator pumps disconnected, I should be able to break the seal between the fish box and deck connection, with a little hydraulic help, aft to forward.

Wonder why Cabo made those so hard to remove? With a macerator pump and other service items below you would think they would be easier to remove and access underneath. Especially since they thought everything else out so nicely. I was in Virginia last week and was fortunate enough to get a tour of Capt. Maritime's 40' Cabo. Beautiful boat that is really laid out well and well designed. Too bad they sold the Cabo brand

Do you know what type of caulking Cabo used at new construction back in 2005? I'm hoping the 18 year old caulking lets go with out too much force.

Yes it was a silicone type caulking. It appears as though the port fish box was removed in the past as it came out very easily. After removal I could tell the exhaust silencer had been removed and re-installed, likely as interference to replace the hydraulic lines to the steering rams. Next to identify where this common bonding connection should be connected. I'm planning to install new hatch seals and new gas lift support struts as well.
