Maintenance

Hull blacking with Pinder in Diglis dry dock. A busy week but managed to repaint the black hull sides above the rubbings track.
Taking the boat out experienced hire duos vibration. No obvious fault including checking the propeller for fouling. Pinder had polished the propeller leading edges to reduce propeller whine. That seemed to work and the vibration was not evident after runing the engine for a time.
Though problem could be thrust plate rubbers to visited for the day for J to complete getting ready for summer cruise and I would replace rubbers.
Disconnected and removed Aquafax coupling. Unfortunately had not left angle irons onboard that I could use to support the gear box. Made up a jury rig and got gear box off and thrust plate out. No apparent fault so replaced rubbers ans started to reassemble. Unfortunately jury rig did not support the gear box to allow it to be slipped onto the drive spline.
Returned next day with angle irons to support gear box. Reftted all. The bell housing on the 1505 is designed to make maintenance as difficult as possible. The bolts have to be started with the housing away from the black and then the bolts tighter and the housing move towards each in turn. One bolt is almost inaccessible and not in line of sight.
Anyway all assembled which left me time to re wire the galvanic isolator that I incorrectly installed about 12 years ago!
