Motor

Your manual will set out the maintenance requirements here. Do not forget to check your motor anode and the impeller in the waterpump. I think it is a good idea to replace your impeller each year and keep the old one as a backup.

Also a simple filter on your water intake line between the gate valve and the pump will save a lot of hassles with potential blockages. Wingate" make a simple clear inline tube one and these are available from farm stores, marine shops and garden centres.

All hoses should be double hose clamped for safety and checked for wall softening or damage. Replace as necessary.
