I'm thinking of opening up the floor on my Humber 7.5 about 2004 vintage to install a through-hull transducer and wonder if anyone has a diagram of the floor support structure.
Cheers
Yep, I'll try and find one for you but meanwhile, you don't need to be concerned because the structure is simple. A V hull with two mahogany longitudinals from the transom to the bow. If you have the single inboard engine as in your profile, you'll find a longit at each side of the engine bay, if you're talking about an outboard engined boat you'll find the longits are attached to the transom by the transom knees.
Hi JW,
Thanks for your input. Yes, I've got an inboard diesel, 150hp Volvo, I believe.
I want to install a thru-hull transducer rather than transom mount it and I also want to investigate the drain from the bow locker as it seems to be blocked. Both tasks require lifting some floor panels and I don't want to tackle it without some idea what I'm cutting into.
Unless you have a particular application which requires you to cut a hole in the neck, then I'd suggest you mount the transducer in the engine compartment. Clean the surface well and bed the transducer into a big skoosh of silicon sealer. Try to lay down the silicon without air voids within it.
