I'm looking for a replacement impeller for my 1994 Glastron SSV 175. It has a Volvo Penta 3.0GL D-MMDA engine. The part number on the impeller says Volvo Penta 3862465 and when I look for a genuine Volvo Penta part it says discontinued. I wouldn't mind ordering a cheaper after market part but I want to make sure I get the right one. First time I've tried to replace this on my own. Your expertise is appreciated.
