OK, here I am your very own MKI technical editor raising my hand for help.

I joined the fleet 9 group for a lovely trip to Petaluma over the weekend, this cosisted of a fairly long 3 hour motoring trip in SKINNY WATER. The fleet was returning on Monday but due to home projects we left on Sunday with the incoming tide. Motoring down river about two hours out of Petaluma, I commented to myself how great the enging was running putting out its constant D D D D D D D at 2500 RPM. About fourty five minutes later at buoy #7 on the way out the channel with very thin water on each side and six more channel markers to go before deep water, the RPM's roll back to about 1500. I first assumed I had bumped the throttle, I moved it up with no joy just black smoke out the exhaust. I thought I had fouled the prop, put the transmission in neutral, engine still would not throttle up. I assumed we had contaminated fuel and plugged filters as I knew we had plenty of fuel and the engine was not surging. I opted to just keep the engine running at the current RPM as it was fairly stable and motor sail out of the channel. We motor sailed for another hour past the Richmond San Rafeal bridge, I had decent wind and figured I could sail the rest of the way home and shut down the engine.

Ten minutes later the wind died, tried restarting the engine, no joy. I replaced both the primary and main filters and started to bleed the injectors and found the fuel pump would not run I figured that was the problem not contaminated fuel. I tried jumpering the power wire from the macerator to the fuel pump and still the pump did not run.

We decided that we would do the ancient mariner thing and just sail. We slowly worked our way past the lee of Angle Island and into the slot where it was blowing 20-25KTS, we were on a ripping reach, the fog dropped and we had an empty tanker bearing down on us with a meanacing bow wake showing brightly and an even more menacing fog horn that tightened the sphincters of all aboard. I knew he would be turning out to sea past Angel Island or continuing south on the west side to Treasuare Island to the anchorage and we were on a course to the south side of T.I. He passed about a quater mile to our starboard but, in the conditons it was very uncomfortable until we could see that his course was west of us.
We carried our high speed reach on past the lee of Treasure Island and under the bay bridge. We made the entrance to the Oakland Estuary about 8:45 PM and the wind quit. The tide was going in and we recieved a little push from that and managed between .5 and 1.5 knots, at times just enough to maintain steerage. a few commercial vessels, ferrys and tugs passed, their wake eliminating our headway and steerage. This went on for several hours until the wind totaly quit about a mile and a half into the estutary. A small thirty foot plastic classic slowly motored upon us and I aske that he tow us at least past Jack London Square where if we drifted to shore we would at least have docks near by. His little 8 HP outboard would only run about half throttle, he took us abeam of Mairiner Village. We let our guests go ashore with our savior were he gave them a ride to our marina. We continiued to ghost along and managed to sail into our slip at 1:30 AM

Now back to my question, it is one I should be able to answer but have come up feble, can anyone tell me the circuit the fuel pump gets it power from, it obviously comes from the engine panel but, I see no reference in my manual about the circuit. I ask as when trouble shooting underway I had jumpered the macerator to the fuel pump and had one of my crew momentaraly hit the switch for the macerator. Later when it came time to turn on running lights we found we had none. We also lost water pressure and some other systems. One of my crew reset some of the breakers and systems came back on line except for the fuel pump. I would like to understand the circuit before I start my trouble shooting of the pump. I would assume the engine harness upgrade schematic would show this but I have no access to it at my office.

As for the pump they cost about $60 from an automotive supply house, I may install a back up with a switch to eliminate another long night on the water. Never liked this aspect of the Universal/Kubota motor, much rather have a engine driven lift pump that eliminates the need for any electrical source to keep the engine running.
