The easiest is a flush kit made and using salt away. If operating in salt water.
Be ready to repace shaft log with dripless. Replacement of water pump ( engine) on routine bases. If the boat is left in water then you will need to buy another boat. It is a fresh water non bonded boat.
If the water has tanic acid from trees you get a corroded internal engine...
I have replaced an engine that dropped a valve from salt water.
