"I was looking for a well designed battery to run my Electric motor on my 17 ft. Aquasport . It is powered by a 90 hp E-tec Evinrude outboard and I use two gel batteries to start it and run all my instruments. This Optimum battery will be my stand alone power source for my electric motor. I just installed it and it runs my motor very well. I hope it holds charge for my slow moving looking for cruising fish on saltwater flats."
