2002 60hp 2 stroke wot problem. Starts fine,runs fine untill. After 4000 rpms it boggs down. Its getting plenty fuel. I disabled the alarm for the oil float a long time ago and mix each tank myself not sure if it matters but has been running fine untill now.. thinking it might be an electricial problem. Thanks for any help!!

hopefully you also pulled the oil pump drive shaft or else the gears will damage the crank without the oil to lube it.
Most problems are fuel related. You need to test what you can at the problem RPM. fuel pressure/vacuum, spark, and timing and then look at the carbs if no problem has been found
