• Shaft diameter: up to 40 mm

• Up to 175 HP & 130hp at 1200 shaft rpm

• Used as a drive shaft alone the CV21 series shaft will take up to 270HP at 2500rpm.

• The maximum speed of the drive shaft: 8000 rpm

• The maximum speed of thrust bearing: 4000 rpm

• 175 HP = 130 kW (1HP~0.75kW)

• CV21 can be manufactured to required length up on request apart from the standart length of 210 mm.

• Standard coupling mounting: Yanmar, Volvo, 4”-5” coupling

• Non-standard coupling adapter kits are custom order.

Sample Application;
Boat Type	Motor Gücü kW/HP	Krankşaft devri rpm	Şanzıman Oranı
Planning	173/235	3800	02:01
Semi displacement motorboat	147/200	3300	2.2:1
Displacement motorboat	96/130	2500	3.1:1

Above example is based on optimum conditions with 2 degrees of CV joint angle. The maximum permitted power must be reduced normally by 10% for each degree over 2.
