Yamaha Motor Battery Service is both straightforward and yet complex
Yamaha Motor battery service and maintenance is simple but keep in mind that different motors require different batteries and this blog is specific to Yamaha Outboard Motors. If you have another brand of motor I recommend consulting your local certified dealer for help and advice.
The main thing that we want to address is your battery’s size, type and the general maintenance will vary and that Yamaha Motor’s recommends a very specific size and type of battery based on the size of your motor.
The manufacture’s recommendations can be found in the owner’s manual. If you do not have an owner’s manual, you can try to find one online or just call the marina we will be pleased to help locate the information that is specific to your motor.
Yamaha Motors are sensitive to the following:
Note Yamaha does not recommend using deep cycle batteries, maintenance free batteries or gel cell batteries. These batteries are not designed for a high starter current or continuous charging.
• Keep battery terminals completely clean of any corrosion.
• All wing type or regular nut fittings must be tightened using a wrench.
• Check fluid levels monthly and fill to indicated level on battery.
• For batteries that are not used frequently, consider purchasing a slow charger for your battery and convenience.

I was born a commercial fisherman's daughter in Cortez, an old fishing village off the west coast of Florida where you can still experience "Old Florida" and get a really good grouper sandwich. I went to school and became an anesthetist, after privileged years of practice, I jumped ship to work in the family business - Cannons Marina. I love my job and the view. I am crazy about my dog. Being out on the water is magical. I still get giddy every time I see a dolphin. Often I brag that I had the opportunity to swim alongside a humpback whale - it was freaky and pretty amazing. Fishing for tarpon and marlin make me happy. My life is no doubt boating, but I also love paddle-boarding cooking and travel.

I have two Yamahas, an 8 hp for a little boat, and a 115 hp 4-stroke. Both have been excellent, and my experiences with Cannon’s has always been top notch. I highly recomend to anyone looking for a new boat or to re-power should consider speaking to the staff at Cannon’s for uncompromising quality and service.
Do the new 2011 Yamaha 150′s have a secondary charging circuit for a house battery?
Hey R Beekman!
Thanks for your question and so here is our answer….Yes all the model years of the F150 Four stroke motors can charge a house battery separate from the standard battery leads. It will require an optional Battery Isolator lead with circuit protection this part can be purchase at any Certified Yamaha Outboard Motor dealer. The lead has a water proof connection that hooks right into the motors wiring harness and then to the house battery the house battery will need to have a common negative connection with the motor batteries. With this setup your motor will charge the house battery whenever the motor is running. Sure hope this answer helps!
Happy New Year and Happy Boating.
