1: Skat trak 9-17 ST-ST impeller in good condition, good replacement for a stock impeller on a stock ski. pump not included 2: Solas YBSJ 14.7- st-st impeller. not sure of the exact spec of this prop PETESKI may be able to shed some light on it, (i beleve he brought it back from the states) Went well on a mod/limited/high HP race ski. Cheers Tim
Its just a J prop, everyone use to run them before they change to a swirl design, better than a stock one.
