This was a critical part to complete a scheduled sea trial. The part arrived securely packed. On arrival, I removed impeller cover to verify the pump had been rebuilt correctly and promptly installed to complete trial on time. The part performed as new stock, no leaks or mods needed. Seller was a good communicator, responding in minutes to my questions. He was very helpful in securing 3 day shipping to Hawaii , time being of the essence. I will definitely do business here again.
