MS 34 Pilot 34 Rumrunner Fuel Consumption

Attached is a little chart I keep around as a guide to fuel consumption on our 2005 Mainship Pilot 34 Rumrunner II with a single 370HP Yanmar 6YLA-STP engine. I cannot recall the source that I lifted it from so if I am infringing on anyone's copy rights I apologize in advance. I realize this is a very different boat from the 34T but thought it might help anyway.

Looking back through our maintenance logs I have found very few if any significant repairs or troubles with this engine over the life of the boat (we have impeccable maintenance logs and work orders since new). A water pump has been replaced, all hoses were replaced with new on general principle (I still have all the original hoses as spares on board just in case), but little else other than routine maintenance and scheduled inspections. The engine currently has around 1450 hours. If well cared for, these Yanmar's should run reliably a good long time. Just keep up on the routine and preventive maintenance.

I would be interested in any feedback on my little fuel consumption chart from other 6YLA-STP owners as to your own experience with fuel burn rates at different power settings.

Thanks all!
Doug
