Hi,
This is my first post so I hope the format is correct. I have an Islander 34 with the original Atomic 4. The engine runs great and we have had no complaints until last week. I noticed a steady drip (almost a run) coming from the upper hole of the water pump so my plan was to remove the pump and replace it. The top water pump bolt is no problem to reach and it is in reasonably good shape. However, the bottom bolt, which I assume would take an 9/16" wrench like the top bolt, is deteriorated to the point where a 3/8" to 7/16" will slip over the head which is almost round.
First, I would like to know how serious the leak is in terms of whether or not water can get into the oil through the defective pump seal? and second, does anyone have any suggestions on how to get the bottom bolt out given the very limited space available in the engine compartment?
Also, is it possible to remove the transmission housing with the engine still in the boat and thus allow for removal of the bottom bolt and pump on the bench. If the transmission housing can be taken out while in the boat how do you reseal it since the pan gasket would most likely be damaged?
Any thoughts would be greatly appreciated.
Thanks,
Bruce
