Re: 150 Black Max lower unit
I think my V150 is an '82... careful about swapping LU's between years. On the early ones like mine, they're the kind that have a preload pin on top of the driveshaft. Sometime later in the '80's they changed driveshaft styles and they didn't have preload pins anymore.<br /><br />The failure on yours sounds like when I broke/twisted the driveshaft on mine 2 seasons ago... found a used shaft (which wasn't that easy) and replaced all the bearings and put it together myself. The gear set was salvagable. On mine I think the upper driveshaft bearing (the one right below the water pump) went bad and was running hot... and probably what caused the driveshaft failure... but who knows, it could've gone the other way around.<br /><br />Even doing it cheap wasn't that cheap. (I think something like $550 in parts including a good deal on the driveshaft, $190 I think) Anyway, it's still working... so I'm happy. <br /><br />I bought the Seloc manual covering our motors, it was useful. Good luck. <br /><br />Brent
