I am thinking of replacing the engine in my old FL boat (not my Bruno DE so please excuse) I would really like to retain my current prop & gear and use a 4 cyl diesel, non electronic. I have been getting some conflicting information from manufacturers.
Current engine 50shp @ 2000
gear 2.6, prop 23X23 5 blade "shrimper style"
My question is this: Can't I select an engine that produces [email protected], limit my rpm's to 2000, and not worry about what the hp is at max rpm's. I have talked with Beta, JD, & Westerbeke and they all have some reason why this won't work and will void the warranty. For the life of me, I don't understand why. I need some common sense knowledge.
I should add that 95% of the time, at crusing speed, this vessel only uses 15-20hp as it is a 33LWL, 26000lb full displacement. Pic attached.
