The old Yanmar 2QM20 was taken out (it had to be dismantled partially to be handled more easily) and a few days later a brand new Yanmar 3YM30 was lowered through the hatch.
The new engine being much smaller and lighter, it was much easier to handle.
The following work was done by the local Yanmar shop:
-Remove the old engine
-Remove the shaft and propeller
-Remove the water intake
-Remove all the exhaust gear
-Remove the fuel tank lid, the fuel line and the fuel sump valve. Clean the tank.
-Fit new water intake, raw water filter.
-Fit new fuel line and valve with a good prefilter, fuel return line and valve, sump valve. Paint and refit the tank lid.
-Mount new exhaust with Vetus water lock
-Manufacture aluminum base plates (1 in. thick) in order to reuse the existing fixation holes and accomodate Vetus silent blocks
-Mount new engine fitted with a special exhaust bend, a 90A Mastervolt alternator and Vetus silent blocks
-Mount a Volvo shaft seal, a new shaft and a big two bladed Radice propeller
Splendid work. The engine is extremely powerful and propels our Nic at around 5.5 knots at 1900 RPM ! Even going against strong headwinds is quite easy now. We just have to be careful not to overpower her! The alternator charges the batteries in excess of 20 amps for each bank at 1000 RPM already.
Here is a picture of the new marvel.
