on my saildrive
VP 130S-B has an axial clearance of about 4 mm (3/16") on its shaft. The propeller
(3-blade foldable) is kept in place on the shaft through a standard spacer (Volvo pn 358 2887) and the propeller hub, resting against a shoulder on the propeller shaft and torqued (70Nm?) up. But still there is the 4 mm axial clearance. Is this clearance normal or is there some wear or is the spacer a wrong one? Anybody knows what the length of this spacer? Maybe someone has put in a wrong spacer? Pushing the propeller towards the vertical main housing, also in forward drive the gap between zinc anode and hub is appr. 1 mm. pulling the prop to the stern (also in reverse drive) the gap is appr. 5 mm.
The face of the propeller hub looking towards the zinc anode (new) has some grooves because of trapped fishermen's lines, between Anode and prop hub. However this problem cannot result in an increase of clearance, only the gap could have been increased. Any ideas?
A line cutter
on the hub could avoid these problems? I haven't found a supplier for these cutters on the Volvo Penta
foldable 3 blade
Thanks for your attention.
