leaking heater pump causing overheating?

Where is the pump located? Is it easy to see for regular inspections?

Mine is located at the rear port side of the engine compartment towards the bottom. Not terrible to get to but not great either.

awesome, thanks. With 300+ hrs on the clock I guess I should probably just drain and flush the whole thing since Indmar recommends it at 300hrs.

Technically it's every 2 years or 300 hours whichever comes first.

Just a follow up on this in case it helps anyone out. I got a new heater pump and replaced the cracked one, drained the coolant out and replace with new coolant(since i was at 300+ hrs). I followed the instructions from Indmar. Spent a few hrs on the lake last week and the engine temp stayed nice an constant around 160. After leaving it overnight I checked the level in the coolant tank and it was a bit low so i topped it off. Everything seems to be great now.

Once I had mine fixed, had to top-off the levels 1-2x and all was consistent after that.
