Since it looks like a challenge, there’s five things I’d like a better idea about before installing an FAE (fresh air exhaust) on an SV211.
The basics are, that the SV211 has a swim platform mounted by removable brackets. These brackets are two pieces and resemble (but are not exactly like) these other models of CC removable (swim-platform) brackets.
[See picture posted, in next post.]
Again, these removable brackets are two pieces, with unknown names, but I’m calling one a ‘hitch base’ and the other a ‘removable hanger,’ which has a vertical slotted-sleeve for seating onto a hitch post of the hitch base.
The hitch base is bolted onto the outside of the boat’s transom (the removable hanger bolted/screwed to and underneath the swim platform). The SV211's swim platform is supported by three such removable brackets. Hence there are three hitch bases bolted on the outside of the transom:– namely, a left, right and center one.
The center hitch base is mounted by six bolts, which extend through the hull, and are secured by nuts tightened from inside and at the very rear of the engine compartment.
TAKING THINGS APART.
1 - What is the best way to get at the (six) nuts for taking off the center ‘hitch base?’ Some suggestion somewhere was to pull out the left (passenger-side) ballast tank. Really? Eek. Access to the nuts has me reaching around at an awkward angle of attack – and behind – a large, cross-wise, horizontal pipe (about 12" OD x 48", I’d guess, and raw water heat exchanger, I’d guess again). As it is for me, those six nuts are at the furthest end of my reach, and my wrist is at no comfortable angle to apply twist.
2 - Does the ‘backing hardware’ for the center hitch base come loose after the six mounting nuts and bolts are removed? I can feel that the nuts are not tightened directly against the inside of the hull’s transom, but against some stress-distributing hardware. I’m calling it ‘backing hardware’ in my questions here.
3- What does that ‘backing hardware’ look like? (If not known, then what’s the best guess.)
PUTTING THINGS BACK TOGETHER.
4 - Is it tricky to get the center hitch base back into correct alignment when re-mounting it (except this time together with the FAE-specific bracket) to the rear of the transom? It appears if the center hitch base has to be aligned fairly accurately such that its hitch post is contained in a vertical plane parallel with the vertical planes containing the left and right hitch posts. In other words, the three hitch posts appear to need to align on parallel axes or else the three removable hangers won’t seat properly.
5 - After the (a) center hitch base and (b) FAE-specific bracket are together bolted/re-bolted back onto the transom, does the FAE-specific bracket interfere with the seating of the (center) removable hanger? It appears that it might.
