Diesel quits in rough water or tight turn

Just another thought. You mentioned the fuel gauge is kaput. Like MMR recommended I'd check to see if there's a relationship between the engine problem and the gauge. The setup I had on the previous boat had both wired into the ignition switch. With a boat of that age, plus the motor installation several years back, you could have an intermittent connection. I'd start checking the wiring at the switch.

On most diesel engines, there's nothing electrical which would cause the engine to die (unless you have either an electric fuel pump or a short in the stop solenoid).

Diesel problems in order of occurence are: (1) fuel; (2) fuel; and (3) fuel. You've very likely got a dirty fuel tank, and maybe some bad or old fuel.

Have the tank cleaned. Make sure the pickups are clear. Change the filters. Check to be sure all fuel connections are tight. Yes, it's a dirty job and a lot of work, but if your tank is dirty partial measures like changing the filters won't do the trick.
