GP1300 Pump damage after forgetting 1piece
After installation of a new pump stator, i ran in some problems with idle and water entering the hull.
it took some time before we saw that the motor moved a little (2cm) to the front, it was flat on the motor mounts (these are now in bad shape)
The rubber inside the midshaft coupler also was pushed out.
When i took of the impeller and shaft, i saw that the impeller was running in the 2inch extension piece, it was boring itself true
resulting in damaging the impeller and impeller house.
the impeller was moved out of the pump stator, because someone (not me ) forgot the spacer (21) between the bearings
So the best thing to do now is to replace the midshaft coupler, 2inch extension (housing,impeller 2) and 4motor mounts.
and of course put the spacer back in the pump.
(WFO already pm'ed for the motor mounts)
some pictures of the carnage

2 more pics,
in the left, there should be a spacer in back of the bearing keeping it from pushed back inside.

Can i re use the midshaft coupler if I seal the rubber back in with some 5200M??
Expensive piece to replace...

I dont think you are going to be able to use that I shaft bearing housing
Ive never seen one come apart like that, but have seen plenty leak at that rubber seal... that thing holds/seals water pressure where it mounts to the midwall

What do you think off that 2inch extension piece (housing,impeller 2), will it affect any performance or cavitation?
if i sand it smooth. the grove depth is about 1,5mm (0.06inches)

Damage like that in the 2 inch extension won't effect performance
