Help needed! Had to end a fishing trip to LA early yesterday due to some issues with my 2008 Yamaha 25 2 stroke. Background info - Just put on a new PT SRA3 10x12 and it ran perfect on Monday. Topped off the tank Monday night with fuel at the marina (3 gallons in a 12 gallon tank) and had issues starting first thing yesterday morning. The motor idles fine, but when you get above 2500-3000 RPMs it will run great for about 45 seconds, then start to bog and lose power. When it does this, the tiller throttle locks and won't let me give it any gas. It would then idle rough for about 30 seconds and clear right up. Run again 45 seconds, bog, etc etc. It was really frustrating making 45 second runs to get back to the ramp in Delacroix Any ideas? I figured if it was bad gas from the marina it wouldn't run well at all. Could it be plugging in the fuel lines causing vapor lock once the RPMs go up? High temperature shutdown? I plan on pulling all of the fuel filters and taking a look tonight. Any input would be great!
