The only bad Sierra impellers I’ve had were for 1970s-2000’s 9.9 and 15 HP Johnsons – they didn’t pump at an idle.
Be sure to lubricate the impeller surfaces before starting the first time – I either smear a small dab of grease on it, or KY-Jelly. The first couple of turns can wreck them if there is any grit in the lines.
