Finished the install of the new idler plate Sunday. It took a great deal of work to get the aluminum plate to fit where the old "mild steel" plate fit the deck well. I had to grind the ears of the new aluminum plate and some of the fiberglass to get it to sit level. The plate wound up higher than the deck so final fit required a 3/8" trim ring (PVC sheet comes in 3/8") between the deck and the pedestal base. I had to caulk the bolts so couldn't find a way to Tefgel them first and caulk. Used 3M UV 4000 cause it works with PVC while Boat Life polysulfide does not. What a mess getting all the cables and wires routed through the pedestal and plate, then caulking, then bolting, etc. Stupid me. In hindsight, I should have bolted up the pedestal to the deck, and run the steering cables and shifter and throttle cables, compass light, and autohelm cable, after. 4" SS bolts were plenty long. Added washers underneath.
In hindsight, 1/2" starboard could be used for the trim ring and saved a little grinding.
A folding rule made a great fish when I had to reroute the electric wires for the compass light.
The new plate positions the idler sheaves lower in the deck well, so I'll have to lower the quadrant on the rudder post to get a fairer lead.
I cut down the SS uprights, reused my old bronze sheeves:
