RE: Fuel Economy Question
"Take a look at the fuel consumption curves of some modern engines."
No doubt , but most "trawlers" have 30-40 year old farm implement or light truck motors.
My own has a 1936 designed DD 6-71.
What a "modern" 30,000 psi rail electronic injected turboed engine has little today to do with most folks.
This WILL change as we see quite fancy auto engines being marinized.
The Yanmar BMW , or Toyota conversions will do quite well at low speed fuel burn , weather they will get 5000 hours at much over half throttle is the question.
