Hi,
I'm currently working on a 144 Yamaha pump.
When I teared it out from the boat (the boat was unused minimum 4 years)
I noticed that the impeller was blocked in the impeller housing.
I disassembled all carefully and realized that the impeller was touching in several points the housing. The housing is in perfect conditions but seems to have some reliefs in it that touch the blades of the impeller. The reliefs are very regular and smooth like as the iron had some very strange deformation.......
I think to grind carefully the reliefs till when the impeller mach the housing liner.
Any advice?
Thank you Michele
