If I enter skinny water and have to trim up the motor (not out of the water) the engine will overheat after 5-10 minutes. The impeller appears to be working as water is still coming out the tell tale at a constant steady stream. No dribble. Not moving fast maybe 3mph low RPMS. All intakes are still under the surface. Once I enter deeper water I trim the motor down all the way and idle until the warning light goes off. Then I take off. At full speed it never overheats. Only seems to be when tilted up and idling through shallows. I got a new impeller in January 2015. Full discretion last year I received some poor advice that it was ok to crank the motor out of water briefly before launching as long as it was only for a couple seconds. This was helpful since I wasn't holding up the ramp when I launched getting a 2-stroke to turn over. Did this about 12 times I approx. last year. Stopped once I saw this overheat starting to happen. I've had the boat and motor for about 4 years and it never used to do this. I've kept up with yearly maintenance as well. I'd welcome some thoughts.
