Sinse end of last boat season my engine has lost its full strenght. It seams ok when idel and low speed. But when accelerating the engine dies for an instant and picks upp speed again. When reaching top speed the force is week and pulsating and engine stalls and drops speed when using trim/til buttons. I allso noticed last year the rpm taccometer often drifts away on wery strange rpms. I have checked battery and other enclosed connections.Bought new coil. And the points, cables and plugs changed two seasons ago. Once I have got god run out of 10, when I borrowed an coil from friend and had it loose on engine? I am greatful of any kind of help and hints. And wish you all good summer. Regards from Finland/Г…land
