boat propeller shaft
Type FR is a propeller system with an adjustable propeller. This is a safe option when the optimal propeller design is not known, or if it is difficult to obtain fixed propellers. The greatest advantage of an FR propeller system is that the propeller can be adjusted so that it replicates a range of fixed pitch propellers.
Maintenance costs are very modest. Yearly maintenance normally consist of replacing the zinc on the propeller. It may also be necessary to retighten the hose clamps on the stuffing box and to refill with lubricant.
Usage: There are no requirements for the maximum exploitation of engine and propeller for a wider revolutions range.
