Here it is on my direct drive. Should be in a similar spot, but flipped around cuz you got a vdrive and the engine "faces" the back. it's not very fun on a vdrive. After you do it once or twice it gets easier... I'm sure you know to change it every year, hence this thread. But its worth repeating I suppose... Got stranded on the water last wknd b/c of a shot impeller. (not in my boat) Keep a spare on the boat and the tools to change it. Oh yea, if you can't find it, just follow the raw water intake up from the tranny cooler. Will lead straight to the water pump.
Welcome to the board and enjoy your summer!
