Johnson 09-812BT-1 Impeller Service Kit

Impellers play a key role in keeping boat engines cool. Malfunctions can lead to engine overheating. In addition to spoiling what would otherwise have been a fun day on the water, that can lead to costly tows and even more expensive engine repairs or replacements.

Experts recommend impellers be changed at least annually to avoid problems. If you use your boat hard, you may want to change your impeller more often. If you are looking for an Indmar water pump impeller, the Johnson 09-812B-1 Impeller Service Kit from Bakes Marine fits most indmar.
