23 IB - Anyone Running a Diesel?

[cc]

I have a 28' boat with a 315 hp, 6 cylinder yanmar pushing. I love it! It is so smooth, very quiet, a responds quickly. I get a tad over 3.2 statue miles per gallon running at 28 mph. Top end is 40mph. I have 400 hours on it. We also have a 1965 seacraft 19 bow rider Dad bought new. Thought about repowering it with a yanmar 4 cyl, but the original mercruiser runs so well. I can't say enough good about the yanmar.
