Super Jet Drilling a 144 pump for dual cooling

[rwilliamtaylor]

I'm about to start a BOB build and I want to use dual cooling. Where do you tap the pump for the second cooling line? It's a stock Yamaha 144 pump.

I don't use the stock bilge and I've filled the bilge hole with epoxy. Can I just drill and tap the epoxy or is there another place to drill and tap.
