travel stats.

I just completed my summer cruise on my 41 DCMY, (6v53s). I cruised from Pt Darlington Ontario, to the St. Lawrence river, and then cruised the 1000 Islands up to Ivy Lea and back to home base.

Total fuel used: 157 gal. (596 Litres)

Total distance travelled: 230 miles

Fuel burn (mixed speeds-1500 rpm -2350 rpm, 8.1 knots-13.5 knots): 1.46 kts/gal.

Average speed : 8.15 kts @ 1500 rpm., fuel burn @ 5.5 gal/hr total, for both engines (2.5-3 gal/hr per engine)

I travelled most of the time at 8.15 kts, but each day, I got up on plane for 1/2 hr to burn of the excess crap. While on plane, speed was approx 12.4-13.5 kt/hr. depending on the wind and wave directions. The stbd engine would smoke a bit (white) for approx 5 minutes, then clear up. Port engine-no smoke at all.

No major engine problems, except for stbd tach cable giving up the ghost. Repair cost was $150.

I did burn off approx. 1/2 cup of coolant per engine.

All in all, a very pleasant and restful 3 weeks.

"I did burn off approx. 1/2 cup of coolant per engine."

I suspect (hope) that coolant was dumped via the overflow tube. No coolant should ever make it's way to the combustion chamber to be "burned."

I asked my mechanic about this. His reply was that with prolonged use of the engines, some coolant is lost, either through evaporation, or through the overflow tube. In any event, this loss was over the entire summer, and not just this trip.
