Universal M25 5421. Temps constant between 185 degrees and 190 with 180 degree thermostat. GPS recorded 7.2 knots on windless morning, sans sails. Factory 2 blade prop. Original RPM gauge maxed at 2600 rpm??? Original alternator. Engine sound and speed with new bottom seemed like 3500 rpm. Engine idles at 600 rpm indicated and smooth up to 2600. Maybe need a new rpm gauge? No smoke, no sign of fuel out the exhaust.
