I own a 1994 Mariner 150 hp outboard. When I engage it in forward and increase the throttle, the gears appear to "skip" (as if there were a damaged gear tooth?). This may stop if I let up on the throttle and then increase the throttle again. There is no problem once I get to a slow cruising speed--only in startup. I need to have a dealer look at it, but would like to know what the problem may be and how better to describe it to the dealer. <br /><br />I'd appreciate any insights you may have.
