I have read many different things about running an outboard on ear muffs. Some say it's OK and some NOT. I do know it is not recommended to run the engine above idle when using the muffs. This motor does have the hose connection for flushing and your not supposed to run the motor on that connection which makes sense as it needs to go to the water pump first to avoid burning the impeller up. I am having a battery charging issue and would like to run it in the driveway for troubleshooting purposes.
- New battery, all connections clean, Yamaha gauge flashes 11.4 to 11.8 when running at 4000 RPM. Sometimes it reads where it is supposed to between 12 and 13.2. I want to test the regulator output while running in the driveway, hence the question above lol. The service manual says to check the connector at different RPM's and gives the output specs. I am trying to determine what thew issue is instead of throwing parts at it to save some cash. Any help would be greatly appreciated. Thanks in advance.

Thank you everyone for your very helpful replies (as usual). All my connections are clean and greased. The only question remaining is where on the motor do I check the stator/generator/alternator lol output and what should it be BEFORE the voltage regulator ? I am going to check it out on Wednesday. I found a free service manual on line but it is a bit vague on test procedures and specifications. Thanks again and catch em up.
