Impeller Kit with Housing 47-43026Q06 for Mercruiser Alpha One Gen II
Impeller Kit with Housing 47-43026Q06 for Mercruiser Alpha One Gen II
Product Overview
Water pump impeller kit with housing for Mercruiser Alpha One Gen II sterndrives and Mercury Mariner outboards from 40 to 350 HP, supplied as one complete kit. It replaces 47-43026Q06, 47-43026K06, 47-43026T6, 47-43026T8 and 47-43026T11, plus Sierra 18-3265 and the 46-817275A1 housing kit. Because the housing, wear plate and cup come in the box, the pump is renewed end to end instead of just the rubber, which is what a worn housing with a new impeller will not fix. Fit it on Alpha One Gen II drives from serial 0D469859 onward, and on most Mercury and Mariner outboards from 1999 up.
