Default Performance info ,27 Seacraft Diesel-D6-350 HP I/O

I moved the post from pics to performance. I just got back from my 3'rd Sea trial with the correct props (G5 Duoprop). Top Speed was 36 Knots at 3500 RPM and I was burning about 14.5 Gallons per Hour. I set it to 3000 RPM and I cruised at exactly 30 Knots, and it was burning 11.5 GPH.Looks like about 2.6 MPG all around. At 2500 RPM I was doing about 22.5 Knots and burning 8.5 GPH. Bottom line, top speed is 36 Knots, I can cruise all day long at 30 knots. It trolls a little fast, 3.6 knots at 600 RPM, burns 0.31 GPH trolling. My Volvo Trim tabs were not working, so I may be able to improve the numbers. It is fairly quiet for a diesel, I will add more sound-down to the engine compartment to quiet it down a bit.. It is an impressive engine package. I think I am sitting at 8000 lbs loaded with 140 gallons fuel, and thats how I tested it.
