Post subject:  Sea water pump impeller location

Question about sea water pump impeller location. I have a 2004 Horizon 200 Volvo Penta 5.0 GXI-E with an SX drive. I have been researching on the internet for drawings of where this impeller is located. From what I have determined it is located on the front of the engine and driven by the serpentine belt. Is there also an impeller in the lower unit?
Thanks

I'm not a Horizon guy, but, the impeller is usually located on the front of the engine, bottom pulley.

The outdrives usually don't have impellers, at least in my dealings with them.

Hope this helps, good luck.

Mercs I know, the Volvos I am still learning. BUT, if you look at the front of the engine, you can tell at a glance. Both Merc's and Volvo's have the standard (like a car) water pump driven by the belt. It you look farther down on the crank shaft, IF you see hoses and a housing. That would be your raw water pump and that impeller should be changed out every year or two. Depending on usage. If there is not one there, than I would "think" it is in the lower unit. Like an Alpha drive.

NO impeller in a volvo drive, the impeller is either mounted at the bottom left side of the front of the engine, or on the crank pulley.
