Bought this oldie last weekend. I can't make out the first part of the model but it ends with "G18734C". Fires right up and seems to idle OK but no water sprays out the weephole. I figure the impeller's toast. I'd like to know the year so I can get a manual and figure out if I need to drop the lower unit to replace the impeller but if anyone has any thoughts on whether that's the issue then that would be great too..
