Hi,

I noticed that during idling, my engine vibrates enough
to constantly hit the water pump on the fiberglass engine
foundation. The last two or three big jumps the diesel does
when stopped bang the water pump into the fiberglass really
hard.

So about about half an inch of the engine foundation has to go.
What is the best tool to cut really solid fiberglass, and how
do I do this? Any advice is appreciated.

Thanks a lot,

Chris
