2 stroke Evinrude 48 SPL 92' model
Engine starts and runs great at first.... Motor will not miss a beat an any speed and seems perfectly fine... However, after about 10 minutes or so (10 minutes of running wide open and about 20 minutes of running half throttle), the engine will begin to miss and lose power, eventually bogging down and shaking alot. Smoke becomes more evident and the engine becomes worse and worse. No overheat alarm has sounded and the engine, while warm, is not excessively hot. The only way ive found to fix the problem is to let the motor sit for a while(engine turned off). The longer the motor sits, the longer i can run the motor before it begins to bog down once again. I recently had the carbs rebuilt by a proper mechanic but to no avail.
Please Help... Thanks alot in advance!!
