Can anyone tell me what impeller I need for a 1989 351W in my TriStar? I want to replace it this coming weekend as I have no idea when the last time it was changed.

Impeller is Johnson 812 (splined). Listed in the faq's.

If it's a johnson pump. I've seen some folks with Sherwood pumps, but I think those boats were a bit older.

Early 80's used Sherwood.

His boat will be a Johnson pump. The Sherwoods are on the PCM motors from the early 80s and prior. All of the Indmar motors use the same Johnson 812 impeller.
