When it bogs down does it sound like engine performance or pump cavitation?
Have you checked the impeller gap? (cavitation)
Have you checked gas tank for water (impurities) - (Engine perf)

It does not sound like engine, engine sounds great. I will check the impeller gap, (get my manual out😁) and no on checking for gas impurities but I will start with these two items! Thank You! So much. Just got new switch box and starting great then this. It comes and goes. Something is wrong. Need to find out what. Thanks again!

Any luck? Took my boat out today for the first run of the season and noticed a strange sound (bogging down) and stuttering in the starboard side engine.
