RE: 3208T on 44 ft Gulfstar
While it will slowly be killing the engine , and not at all fuel efficient , most folks dont care.
The 3208T will frequently run 5000+ hours of normal (half throttle) use.
The usual minor hours of a trawler 300? a year will take a decade to get to 3000hours .
A 20 min shot of heavy throttle every 10 hours will help.AS operating at at least 1 lb boost would also help.
Many old engines simply had the turbo added , not a special turbo build with lower compression ratio pistons etc.
Perhaps a conversion to an NA is possible with simply tossing the turbo?
"would be a realistic fuel burn rate at the slower speeds?"
This will be up to you to figure , and will be interesting as a higher speed 7K or 8K might not cost any more than 5K due to engine efficiency.
A Flow Scan will answer the question easily, for a price.
