Assistance towing is tough duty on an engine: high speed planing to get to the caller, time spent at part throttle washing the silt out from under the grounded boat and light throttle 5 kt towing back to port.
Anectdotal stories says that gassers get 2-3000 hours before replacement.

You wouldn't use a 454...you would use a straight six (like a Fort 300 cu in or even smaller) with a high reduction gear I would think.
