I'll have to show my ignorance of Diesel Engines here but wouldn't it prolong the life of an engine if it didn't have to run at 80% to 90% load on a consistent basis? I thought I would be ahead of the game If I had a 30HP engine on a 12,000lb boat with the proper propeller.
But that's why I'm here, to learn.
Thanks for any feedback;
