I'm giving you tournament guys 48 hour to catch up while I'm sitting on the beach.
On my trip to La Jolla on 5/19 I thought the boat was running 5 to 10 degrees warmer that the last time out. When I get home and do the engine flush the pump isn't sucking much water. After a little trouble shooting I find she's sucking air from the area of the intermediate housing.
I found a $3 bushing missing that centers the top end of the water tube. The bushing missing caused the o-ring to pinch on the bottom end of the tube.
All this so I could get to a $3 plastic bushing. #11 on the drawing
