I`d like to thanks all in this forum who help me in my AZ 37.9 refit.
After 2 years ownership and some interiors and other minor refits until last summer I finally can start an serious mechanical refurbishment and have now my Azimut like new and ready for many years of safe navigations.
I calmly start this project in last January and have tested all the results last weekend.
For those who wants to appreciate and take some knowledge for my (little) experience I left here a resume of some works done in this period (all spare parts and consumables original Volvo Penta):
Mechanical / motors (2x TAMD61A):
Fuel System: diesel tanks out and serious clean; injectors and diesel pumps supervised and refurbish. New diesel fuel lines and extra size fuel pre- filters / water separator; new diesel filters. Replaced rubbers, rings, O-rings, gaskets, etc.
Exhaust System: turbos refurbish; exhaust system “pipes” clean. Pre-heaters and by pass valves. New crankhouse ventilation filters. Replaced rubbers, rings, O-rings, gaskets, etc.
Lubrif. System: annual revision set up; filters, oil, etc. Clean all system. Replaced rubbers, rings, O-rings, gaskets, etc.
Cooling system: Sea water pumps, impellers, heat exchangers and after coolers clean, expansion tanks clean. Replaced rubbers, rings, O-rings, gaskets, etc.
Eletrical: instrument panels, service batteries, fuses, etc.
Others:
Reversing gear supervised and oil changed
Steering system r supervised and oil changed.
New Fresh water pump
New bilge pumps
New outside saloon windows design with UV protection filters
New covers and fly bridge cushions
Etc.
Conclusions and benefits:
Boat appearance and seamanlike 10 or 15 years newer.
Fuel consumption reduced for same cruising speed: 50 lt /h
Cruising Speed = 24 Knots at 2200 RPM
Max speed = 30 knots or more (I don’t want to over charge more than 2600 / 2800 RPM).
No smoke after 10 minutes starter.
Cost: about 12 K
For better understanding I attached some photos (if forum let me do it).
Many thanks again,

PS: best kick – fuel tanks clean.
