For replacing the Yanmar 128377-42500 pump model, it is essential to use the JPR-YM08IH2 pump model due to variations in revolutions per minute. While the flow rate of JPR-YM08IH is higher than JPR-YM08IH2, it is important to note that this doesn't make it suitable for both Yanmar numbers 128377-42500 and 128397-42500. To ensure proper replacement, specifically use the JPR-YM08IH2 when replacing Yanmar 128377-42500.
