I would look at the bearings & shafts, need to pull the powerhead to replace impellers (2), check the watertube seals too. Pumps sit high & need good seals to prime, Local bearing store will have new bearings,
SOMEONE? What’s the John Deere grease called? Use 105 for assembly. Those mtrs have almost as many powerhead needles as Merc’s then! I have a CD manual but can’t get it to open
