I have an overheating engine.

I have an overheating engine. I am fairly certain it is the lower unit impeller. also bought a yamaha i/o before i realized their rarity. my mistake. I think I need a new impeller in the lower unit. Any advice as to where to find an impeller for a gm 4.3l v6 1991 yamaha i/o in the lower unit?

"By the jabsco impeller on line ($20.00). Somewhere in this forum there is a link to a yamaha sterndrive forum that has a step by step answer to your question. I have the same boat and sterndrive. Not hard to find the impeller at all, Jabsco.com"
