This weekend we decided to start our scheduled engine service. Being our third year into owning a yacht, we are still learning, documenting and trying hard to remember all that needs doing…constantly.
First step was the impeller.We thought that would be a nice easy start to our engine service. Last year we had a lot of difficulty with getting the plate off. I had tried to use a flat head screw driver. Nope, I couldn’t budge those screws, so ended up calling our engineer friend, who swiftly made a trip down to the marina and talked us through every step of the impeller change. This year, we were very confident in managing this task ourselves. I now know that we need an 8mm spanner to move those screws. Oh, and whatever you do, don’t drop anything into the bilge. Butter fingers fail. Lucky Pete has long arms. Fantastic, we got through step one. Getting the old impeller out proved a little bit tricky. Eventually, and I will not disclose how long it took, we got the old one out. Putting the new impeller in should be a breeze, right. Well, it will be now that we know it needs to be greased first.
This whole process took us close to three hours. I kid you not. The hard part is mainly due to the engine configuration. The array of hoses that get in your way and the lack of space makes an easy job take such a long time. However, the smile on our faces and the huge feeling of success was beyond words. We did it. By ourselves.
Step two, air filter change. Too easy, out with the old , in with the new.
Step three, extracting the oil and replacing the oil filter. Extracting the oil was easy this time, as we made sure we ran the engine for at least 15 minutes. Changing the filter and filling the oil tank was straightforward. Unscrew the old filter it will be filled with oil, so be careful. Get the new filter and line the seal with oil from your finger. Screw it in place. Fill the oil tank with oil. Check the oil gauge. Done.
Step three. Fuel filters. There are two of them a primary filter and secondary filter.
Remove the top handle from the primary filter.
The secondary filter.
Easy as. Unscrew the filter. Line the seal on the new filter with fuel from your finger. Screw the new filter in place.
The last major step. Bleeding the Engine.
It was difficult getting photos of this process, due to the location of parts. Basically, I had to pump this little lever, (Pete says it is the manual fuel pump) which I couldn’t see just had to feel for it, until fuel flowed freely from this screw which was loosened to allow the air bubbles to escape.
It took a lot of pumping, eventually the air bubbles subsided and fuel flowed.
We started the engine with all fingers crossed hoping that we did everything right.
The engine started. the water flowed out of the exhaust and she ran really well, After running her for a bit, we turned off the engine and gave it a good clean. The end result, a fully serviced clean engine, ready for dry season sailing. A fantastic result.
The more we learn, the more confident we are becoming in our ability to do some long term cruising. With the knowledge we are gaining in rough weather during the Wet Season races and our ongoing knowledge of the engine and electrical system, we are confident in our ability to be somewhat self sufficient. If Captain Pete could learn how to catch a fish, that would be a bonus.
