Somewhat of a ‘here we go!’ moment to put the drill to the bottom and go straight through! Reminds me of the joke: “What does a belgian (fill in your neighbouring countryman here) do when his boat has a hole and water is pouring in? .. he drills another hole, so the water can flow back out.” Ghe.
Anyway, my father brought his milling machine to mill a circle out of the bottom plate and the saildrive fits superbly.
Next up: mounting the motor to the saildrive.
