Dear All, I faced a problem with the SM 2000 Alma Libre which I want to share with you just in case you have the same problem in the future. We were motor sailing with 8 Knots and suddenly the boat started to slow down and the motor started to increase rpm. Immediately I reduced the throttle and opened the engine room which was messed with red colour Automatic Transmission Fluid (ATF). The problem started from a leak between the hydraulic gear box and the valve of the shaft break. I was able to locate the leak and stop it but I could not use the motor as the quantity of ATF I had with me was not sufficient and I was afraid that by using the motor without enough ATF I could damage the hydraulic gear box . In the mean time I spoke with the Technical department in Amel and they advised me to unscrew the large screw in the back of the shaft break cylinder in order to disable the break as it needs a lot of hydraulic pressure to be disengaged when you start the engine and I continued by sails ( 9 hours) until the next port to find and fill the gear box ATF. So carry with you at least 3 Litters of ATF it may be necessary in case of a leak.
