The Cummins started being installed in trawlers in the 90s. Even though it is a great engine for a trawler in its 6BT configuation, I suspect your budget will lead you to something older.

Lehmans have fantastic support from American Diesel, the guy who originally marinized the Ford.

But a normally aspirated Perkins would be a good choice also.

Both were installed in trawlers from the mid 70s into the late 80s, early 90s.

You sometimes see Detroit 8.2s in trawlers. It doesn't have a good rep. Detroit 4-53s were installed in the Hatteras LRC and while a very solid engine, are noisy and vibrate at low speeds.

Most other marine engines don't have enough displacement to go low and slow while pushing a 20,000+ lb boat.

So Cummins, Lehman and Perkins would be my choice.
