As already mentioned a decision to change the engine ( a Kubota D-950-b) was taken in August 2003. The reasons that lead to this decision mostly reveal continues problems due to a bad recondition of the engine when purchased (that didn't show so soon) and also a bad marinisation of the engine that was originally built for a tractor.
The new engine is a Yanmar 3GM30F fresh water cooled marine engine by design. It is reconditioned by my mechanic who bought it used but checked and replaced every bit that could cause trouble. Along with the engine comes also the reduction gear mechanism bought as a "package". The engine was completely bench tested and I had the opportunity to follow up the rebuilt (although at the time I have not had a camera so as to take pictures to present here).
The engine was moved aboard Efaki on Sep 4th 2003 at the same time that the old engine was removed. Efaki has been hauled out at Kalamaki (Alimos) Marina for the purpose of re-engine and by the chance for a new coat of antifouling.
The hard ground is really empty this season. It's early for boats to take the ground in Greece.
These are the stands that the crane operator hired me. I'm thinking for a long time to construct myself retractable stands that I'll keep at home when not in use. Probably I'll take exact measurements of these so as to know the needs of Efaki and some time in the future get to construct them.
This is the new engine. There is no need for modifications to the engine beds on the boat but probably a new shaft will be needed as the present one is 3.5cm short of what would be the ideal. The exhaust equipment (hoses, silencer, anti siphon valve, etc) is of the same dimensions and will be kept as is. The exhaust of the new engine comes out on the left side and so the hoses will be permanently moved near the bulkhead as shown in the picture above (here it is temporarily placed so as to observe things being ok).
We also thought of changing the stuffing box since the one I have is old type (the one with the packing thing). Although probably this wont happen since there is not enough space in the little keel to drill for the replacement, but we have to see that.
The new engine has not an electrical panel. A new one costs about 300 Euros which I consider expensive for a tachometer and three warning lights and a buzzer. So I bought the tachometer for 80 Euros and I'll construct myself the panel. I have the wiring diagram and the parts wont cost me more than 20-30 Euros with the wires and the Plexiglas panel to install them.

Update: September 9th 2003
Today I'll start constructing the engine panel. This will have a key switch for setting to "running" and a button for the engine start. There will be three warning lights: charging, oil pressure and water temperature and a buzzer (sound alarm) connected to each one of them. The panel will be created from Plexiglas. Of course there will be a fuse and all the other bits and pieces to make it not only functional but even better that the original. Ok, it wont say Yanmar on it!! but this is not really a problem for me. The tachometer will be placed in the existing hole of the previous engine's tachometer in the cockpit.
Update September 15th 2003
Last Thursday I painted the engine room so as to be ready for the engine installation. At Friday the inspector of the Marine Mercantile Ministry Inspection came on board so as to check the serial number and the type of the new engine, the shaft and the propeller so as to renew the Protocol of General Inspection of Efaki before the complete installation of the new engine.
On Saturday my mechanic temporarily installed the engine on the engine beds so as to mark where to drill the final position of the engine mounts (bases).
At the same time he completed the checking of the stuffing box by replacing the plastic bearing on the out edge since a new shaft is installed. Also a new elastic coupler will be installed between the engine and the shaft coupler to absorb vibration. This is a relatively new piece of gear made in France which my mechanic thinks that will ease the vibration of the engine mounts and at the same time help the new shaft last longer (here in Greece every four years we have to take out and have checked the shaft for damage. On Efaki in order to bring out the shaft you need to remove the engine since it can not come out on the outside since the rudder skeg prevents that).
On Saturday I also scrubbed Efaki to have it ready for the new antifouling. The process as always was painful !! I also forgot to bring the protective glasses and all night long I had my eyes suffering my stupidity. Thank god Efi had some collyrium that eased the pain.
Yeah, this is me! On the center it is a "before" and in the right an "after" picture of sanding the hull.
Today my mechanic completed the installation of the engine. At the same time I'm almost ready with the engine panel that I construct myself. If I manage to complete it today, we'll launch Efaki tomorrow.
I used the engine panel of the old Yanmar YSE 8 to cut from Plexiglas a new one. Then I drilled it to suit the bits and pieces needed on the new one.
The new panel incorporates a master fuse, an on-off master switch (no key) a buzzer and three alarm lights for low oil pressure, charging and cooling water temperature. There is also a button for the engine start and two more buttons that control the anchor windlass (the main control is at the bow but I thought a second control station in the cockpit would facilitate single handed sailing).
Update September 17th 2003:
I splashed Efaki yesterday since on Monday September 15th I managed to complete the wiring of the new engine and applied a new layer of antifouling with the help of my wife Efi (of Efaki...).
Go to the launching 2003 page to see how we splashed Efaki on September 16th 2003.
