Lower Unit - SELVA MARINE Blue Whale 250 EFI Service Manual

Lower unit

A spring has been added to the lower unit for the Blue Wlale 250
The spring is used to push the drive shaft toward the water pump and stabilize the thrust free play of
the shaft.
This spring facilitates the backlash measurement procedure since the lower unit does not need to
be turned upsidedown to carry out the measurement.
