    Merc 250 Verado Fuel increase

    Good, never start engines with the charger in operation. OK, those LEDs are the neutral indicators. The LEDs I was thinking about are on the port/stbd start/stop buttons. What do those LEDs do when you do the all start? I'm guessing the double beeps you get during cranking are due to the...

    Looking at your voltage readings. When you started testing had you burned off the surface charge on all 3 batts? Please make sure you do this before any testing if there might be a surface charge. The numbers at the batts look normal and tell us that the house battery is getting charged by at...

    This isn't how the manual describes sequence of start event. If you are talking about the LEDs on the port and stbd start/stop buttons on the aft face of the control? Are you starting these engines with shore power and batt charger still connected and on? But I have no hands on with this ayatem.

    The Dual‑Engine Battery Architecture Diagram I posted comes from the VERADO V8/SEAPRO V8 INSTALLATION MANUAL p/n 90-8M0156798 This should have been in your owners packet that came with the boat. The Start/Stop All Engines I posted comes from the Electronic Remote Control OPERATION MANUAL GEN...

    Oil 4 stroke Mercury 115hp

    IIRC that was about 4 decades ago. Information like that has been changed many times since then.

    Oil 4 stroke Mercury 115hp

    O.P. says this is a new Mercury 115HP Outboard. I would highly recommend using what the owners manual has in it. Application determines specifications. Google the Motor Oil Geek on YouTube. That Lake Speed Jr. know his stuff! But yes the prices blow my mind. I'm back in the business working the...

    Take a look at 8M0156798 install instructions page pages 40-41 Some builders will use a buss bar for the negatives and that's fine. But the clean power connections must go straight to the correct batteries.

    Oil 4 stroke Mercury 115hp

    Since 2014 10w-30 has been recommended for the 115. Make sure to use the Synthetic Blend You can use the 25w-40 if your operating in a hot climate, check your owners manual. Make sure to use the Synthetic Blend

    Thanks for the info, it helps. Do you have 3 or 4 position key switches? A 4 position will have an accessory position if you turn it counter-clockwise. Have you tried using the start/stop all button that's on the pivot point of the port throttle handle? This should start the stbd engine first...

    I'm not sure you have a battery problem. Here is something I found in one of DTS service manuals. Additional Horn Denial: A double rapid horn indicates denial of the attempted action. To help me better understand your boat; Can you post some pics of your dash? Need to determine what exact...

    What does the battery test report say? The 10% is a recommendation NOT a requirement! You're good as long as your batteries get to float voltage before you use them again, Odyssey can deny warranty for many reason per their terms but as long as they get charged completely before the next use...

    So they both get louder when you turn it on to sport and they both get quieter when you select stealth? How are you turning it on/off?
