Mariner 25hp 2stroke outboard. runs fine when idling then after a flat out run for about 5-10 minutes then heats up and cuts out. i think its the impeller but it seems to exspell water fine when running slow. anybody have any ideas?
Change Water Pump Impeller ,
Remove Thermostat And Check To See If Opening In Boiling WAter Clean Ou Any Sand Weed etc, REfit try Again

With what you said.get the water pump done.A little bit of rubber is cheaper than metal.If the motor has a few years on it,the pump does need to be replaced.If the motor overheated after a few minutes,the pump needs replacing now.Yours sounds like it's on it's way out.A bit of sand etc. can do a fair bit.Hope this helps
