Gluing an epoxy puck in the center of the hole:


Grinding back the laminate:


Fiberglass patches on outside of the hull:

Great job. Now, put some barrier coat on that spot.

[hilbert]

Oops, I wasn't clear. The 4 coats of epoxy primer (Pettit 4100 white) is a barrier coat.

Although I use West Systems guides, I find their products to be expensive.
For epoxy, I use Clark Craft's Epoxy-Plus marine epoxy at $64/gallon, when purchased in three gallons quantities.
Over the past several years, I have been using between 3 and 5 gallons a year, so the price really makes a difference.
It also has an easy to use 1 to 1 mix ratio and no amine blush.

Hilbert:

Should there be two (2) hose clamps on each side of the engine's raw water filter or is there not enough bronze pipe to accommodate two hose clamps

[hilbert]

On the outlet side, the bronze fitting has insufficient length to accommodate two clamps.
