The transom drain plugs were cut out with a hole saw.
Fiberglass tubes were fabricated and epoxied into the holes.

A hole saw makes quick work of cutting out the exhaust outlet holes.
|
Interior view of the transom. A 3/4" marine plywood backing plate was
fabricated and epoxied to the transom.
|
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.

The Gibson Transom Mount Power Tip mufflers look sweet !

We reduced the 4" OD stainless pipe to 3-1/2".
|
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.
|
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.
|
With the transmission hub installed, there's just enough room to insert
a hex key to tighten the end-cover bolts.
|
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 !

Here's the last of the interior epoxy barrier coating. Round 2 will be followed up
with a sprayed urethane clearcoat.

Once the clearcoat has been applied, we can start the carlings and deck !
|
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.

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.
