Yanmar Newbie. Finally success
We splash on Thurdsay, so Yesterday was paint day and today was re-energize the "Iron Sail". We have a Yanmar 30GM Freshwater cooled model (27 hp). I ahve never changed the filters on our engine as this is the first year we have had her. Changed the oil last winter before we put her away, but today was fuel filter and water/fuel separator day.
Reading the engine manuel, input from a bunch or others, and finally a step-by-step tutorial by a Yanmar mechnaic I got it to re-fire.
The Water Separator/Fuel Filter was straightforward, but the Engine Filterr was a PITA. I filled the fuel filter cup as much as I could when I changed it, then screwed it on. However, I tried to use the hand fuel pump lever to pump the fuel/bleed the air, but it didn't seem to be moving the fuel at all. I pump almost a hundred times, but still nothing out of the top of the filter unit. I got frustrated so I removed the top screw and dripped in fuel with a disposal pipette until it was filled to the brim. Then I screwed the screw back on.
Do I have a bad hand pump or does it move only a frew drops at a time? Once the engine started it was a little rough, but then smoothed out nicely. I pumped about 5 gallons of water out of the exhaust, which took about 4 minutes, repeated and then shut her down. All guages and pressures looked normal.
Once when that engine ran smoothly i yelled out "It's Working!!", like young Ankin Skywalker did when he finally got his POD racer working in the Star Wars/Phantom Menace.
