Prop Nut Kit 11-52707Q1 for MerCruiser Alpha One Bravo 1 2 3 Sterndrive
Prop Nut Kit 11-52707Q1 for MerCruiser Alpha One Bravo 1 2 3 Sterndrive
Product Overview
Propeller nut kit for Mercury MerCruiser sterndrives, supplied as 1 x prop nut and 1 x tab washer. It replaces 11-52707Q1, 11-52707A1 and 11-52707A2, plus Sierra 18-3701. Fitment covers Alpha One, Bravo 1, Bravo 2, Bravo 3, Vazer, TR 200 ratio, TRS 1.50 ratio, and the 165 and 120/140 models listed below. The tab washer locks the nut against the prop shaft so a prop cannot spin off in reverse; both parts are meant to be replaced, not reused, whenever the propeller comes off. Fit a new kit when the tabs have been bent twice, the nut has lost its nylon insert or the threads show corrosion.
