not able to speed up

    Boat has run fine this season so far until today. Although, it has been smoking quite a bit when first starting out in the water ~ very white smoke. Ran well today until late in the afternoon. Now when we want to speed up (from about 5mph) you can hear the engine rev up but do not go any...
