With new motors in place, here are a couple of videos showing how to flush them after use for a couple of minutes: This extends the life of the engines by rinsing out the salt water. One change since the videos were filmed: we now have our own blue expanding hose, so no faffing with connectors, they are already on the hose.
1st – connect the hose to the engine – DONT RUN THE ENGINE as this flushing means its not cooling the engine
After flushing, disconnect, then DONT FORGET TO RECONNECT THE HOSE on the engine.
