The 3208 up to and including the 375 was and is a great engine. A 30,000 gallon lifespan before a rebuild if she hasn't been overloaded. Parts are still readily available. Try and get a good estmate on fuel usage to know where you stand.
ok you guys say total gallons of fuel burned pitou says 30,000 gallon life span do the math at 10 gal per hr thats only 3000 hrs on the motor or do you mean 300,000 gallons
