Welcome to iboats and maybe.<br /><br />You might have picked up some weeds. They foul the prop and suck air from the surface if it gets bad enough. The water pump intakes can clog as well. Otherwise the intakes are well in the water at any trim angle on your average setup.<br /><br />There are a few things I automatically do when I get a used motor. New sparkplugs, fresh gearlube, and I rebuild the water pump. Otherwise you never know how old they are.
