Re: 1997 Evinrude 50 hp spl
Rodbolt is correct. The SPL models would usually have a simple low output charging system without a regulator. In the case of the 28, it had a different lower unit. There was no zinc anode protection on the models either.<br /><br />For the most part they were made in 28, 48, 88, and 112 hp configurations.
