Click to enlarge. The transom drain plugs were cut out with a hole saw.  Fiberglass tubes were fabricated and epoxied into the holes. (19-JUN-2007)

Click to enlarge. A hole saw makes quick work of cutting out the exhaust outlet holes. 

Click to enlarge. Interior view of the transom.  A 3/4" marine plywood backing plate was fabricated and epoxied to the transom. 

Click to enlarge. The inside lip was waterproofed with one layer of 6-1/2 ounce fiberglass cloth.  The hole was drilled 1/8" oversize to allow a thick bead of sealant around the exhaust tip's circumference.

Click to enlarge. We reduced the 4" OD stainless pipe to 3-1/2".

Click to enlarge. The rough-cast aluminum Velvet Drive bellhousing was brought back to life with many hours of sanding and polishing.  We fabricated a torque tube guard adapter which mounts to the transnission's end-cover.

Click to enlarge. The cap bolts were replaced with hex head bolts in an effort to gain more clearance.  The base was cut from a piece of 1/4" steel plate.  A 1-1/2" wide slice from a 6" well casing was welded to a larger pipe which was in turn welded to the mounting plate.

Click to enlarge. With the transmission hub installed, there's just enough room to insert a hex key to tighten the end-cover bolts.

Click to enlarge. Slots cut into both sides of the part allow access to the hub bolts.  I wasn't able to find a manufactured adapter, so like many parts on the boat, you have to build your own.  It won't be a real Hot Rod unless it's got a bunch of homegrown parts on it !

Click to enlarge. Here's the last of the interior epoxy barrier coating.  Round 2 will be followed up with a sprayed urethane clearcoat. (11-JUL-2007)

Click to enlarge. Once the clearcoat has been applied, we can start the carlings and deck !

Click to enlarge. We fabricated a frame truss plate to span the stuffing box at frame # 4.  It's made from 3/8" thick T356 aluminum plate.  The v-drive and transmission mounting plates were bolted to the stringers with 3/8" stainless steel machine bolts.  Also visible in the top left corner of the photo is the carling.  We'll have more pics of this after it's been all glued up.

Click to enlarge. We'll be installing a stainless steel pop-up bow light in the strongback.  This will require routing out a rather large hole which will seriously affect the member's integrity.  We therefore laminated three pieces of 1/4" 5-ply marine grade plywood to the douglas fir strongback.  This will retain it's curved shape.
