Re: 1999 Mariner 25 hp-Points or electronic ignition?
I havn't seen a 25hp with points. marine motorcycle and small engine power product havn't used points for close on 20 years in most cases. Far more advanced than car product. On the port side your engine there should be a black box with aprox 5-6 wires out of it. On top of the engine there are two coils just back from the starter. This engine is electronic igniton. Why do you ask ?
