    Hello, new here. Just recently bought a rare, possibly one off shoal runner boat. Has a "The Hawk" model 12s jet pump. Need parts or cross reference for impeller plus who knows what else. Cant find info on it at all, anywhere. Also has a strange motor im having trouble finding info on. AMW 60hp 2 stroke. Cant find info on it and need a starter. Hoping someone can help, because i woild like to get it running with the original, unique set up as opposed to starting over with a jetski set up. Thank you ahead of time for any help!!

    Someone just private messaged me saying im on a boat page, not an airplane page. I cant reply to it for some reason. But this is in a boat. Its The Hawk is a late 80s jet drive similar to a berkeley but small. Thats all I know. AMW marine 60 hp 2 stroke(yes they were also used for planes and drones, all i can really find) and The Hawk 12s jet drive.

    Hi, the "Hawk" was produced "Marine Jet Pumps, Inc.", Oklahoma City, Oklahoma. The 12 S has an impeller diameter of 120 mm (4.75"), and was said to be designed for the 40 to 60 hp and 6000 to 7500 rpm range. Afraid there isn't much info available today, and as for the engine - haven't got a clue. But it might be possible to find someone i OC who knows the whereabouts; good luck!

    Thank you! Ive found that info but not the impeller size you just mentioned. Thats the main thing im after. Do you think an aftermarket impeller that size could be fit into the pump?

    What is the problem with the original impeller in the first place, and what material is it? Is there any info regarding engine output and speed (redline on tacho or similar)?

    Generally speaking, as long as there is at least one blade with a reasonably intact leading edge and one blade with a dito trailing edge, a rebuild is possible. Finding a substitute requires hub and shaft dimensions; then a search among the impeller manufacturers might be possible, but my basic take is to check the original first. Got any pictures?
