I'm flipping through the manuel on my Evenrude 200hp 2004 year outboard and in the battery section is says to never install an after market batt isolator. It goes on to say it has a feature that can charge the cranking and acess. batt at the same time. It doesn't say what could result if I did. Any advice? Is this kinda like when they say only use Evenrude oil or could I mess the engine up installing the BlueSeas add a battery system?
