I flush the motor after every use but recently I find that if I spin the prop by hand it sounds ruff as though there is a bearing running dry and grinding. Does anyone know if there is a bearing behind the prop and could I replace it myself or would i have to take it to a marine mechanic, Any advice would be apprciated thanks.Wed, 05 Nov 2008 22:37:46 GMTsnookercue
