Re: 2000 johnson 90HP battery
Since we have no idea what you had and what you bought, the only answer we can give you is the "right" one. That would be a battery marked "Marine Starting" or Marine/RV Dual Purpose Starting/Deep Cycle. You need to look for the CCA (cold cranking amps) or MCCA (Marine Cold Cranking Amps). An absolute minimum rating for a 90 HP is 360 CCA. A 550 CCA battery is just a couple of bucks more and would provide almost double the capacity.
