Up at 6:30 underway preps, less than yesterday, the covers are already off the windows in the dodger and the screens are up. Breakfast, the net.
Well, the packing on the shaft needed to be adjusted, but that drains below the engine room floor, along with the AC. So, that’s not the issue. The investigation continues.
Finally!! We have the “smoking gun”. Most people run these engines at 2000 rpm maximum, I don’t know where that comes from, but the Yanmar manual clearly shows the normal continuous duty rpm is 3000, with 3800 rpm for up to an hour. I run ours at 3000 rpm, the difference is 4.5 vs 6+ knots.
At 2000 rpm, no leaks, but at 3000 rpm there is a steady stream out of the raw water pump. Upon further investigation two bolts were loose. The o-ring was flat, so a new one (yes we had one) was installed some cleanup and then we will see what we get.
We ran up to Isla Partida north of Espirto Santo and anchored at Ensenada Grande. The engine room remains clean and dry!!
Carlos and his wife worked on the boat from about 9 am to 1230. Then we immediately got underway as the next boat to rent the slip was pulling in. Very close!
It was a calm night, good sleeping weather.
The other things are distance to the next waypoint (34.78) time to the next way point (6 hrs 24 min) Speed through the water 4.5 knots (not calibrated yet) speed over ground 5.3 knots (from the GPS). Time in 24 hour clock format 13:16:43 (1:16 and 43 seconds PM).
Direction we are going 337 degrees, and finally the depth of water 91 feet.
