Hi, I just bought a triton boat with a mercury 150 efi. I took it to the lake and it wouldn't start at the end of the day. I boosted it and it started. I noticed when we first got on the water the amp gauge was only around 11.5 volts. When I got home I checked the alt charge with my meter and it was around 11.5 volts. Would anyone know if mercury warranties problems like this. The boat is an 2007. Just thought I would ask before I start to remove the alt and take it in to get tested. Thanks
