I am looking at buying a 15ft runabout with a 1990 Johnson 88 hp SPL. I am interested in Skiing and general boating. The motor appears to be in good shape. It does have a few bumps and scrapes on the bottom of the lower unit. Was the 88 SPL a reliable motor? Can it pull larger skiers? Will the bumps and scrapes on the lower unit affect performance or longevity?<br /><br />Thanks
