The original engine on our boat was a Volvo
MD40A and at about 7,000 hours, had developed so many problems that a rebuild
or replacement was necessary. I was going to rebuild it myself but the parts alone came to slightly over US$20,000 and that didn't include overhauling the transmission
We bought a Beta Marine
90 for about US$16,000 (with a new transmission) and have been delighted with it. It now has over 2,500 hours on it, has consistently started quickly and run smoothly, has never leaked a drop of anything and burns less than one gallon per hour at cruising RPM
. Beta Marine
recommends lubricating oil
changes every 250 hours but in the owner's manual for the Kubota MX-6 excavator, which uses the same engine, it says to change the oil
every 500 hours. Which do you think gets worked harder: A piece of construction equipment
or a sailboat engine?
Fair winds and calm seas.
