Having purchased a 225 j/son which now has 90 hrs on the clock i have already fitted a new p/pack and two coils,sometimes the alarm goes off with a continous tone sometimes with a manic beeping,im at a bit of a loss with the thing,it propels a 25ft speedboat i only rev it to 4000-4500.<br /><br />When the alarms sound i have, good fuel pressure, clean filters ,full oil tank, excellent water pressure 25-30psi,good quicksilva tw3 oil always used.I have tried surface firing and normal plugs(gap 30 thou).<br /><br />Is there anything i am missing ?<br /><br />I always warm the engine up gently before use(its always 30c here anyway).<br /><br />I have a 16v charge indicated(good battery and greased terminals)<br /><br />The engine sounds great misses occasionally and revs drop to 3500 max.<br /><br />Do i go back to mercurys?<br /><br />Are johnson 97 engines fundamentally flawed?<br /><br />Please answer with any quirks or operating hints on these engines,all advice gratefully received.<br /><br />Cheers Borneoman.
