2003 Tohatsu TLDI alternator question

[sgrem]

What is the alternator output and do they make a higher output alternator? Like the one for the 115 or 140....will it fit and work and have higher output on the 90?

I have a flats boat so weight is sensitive. I have one battery for everything and I am on the trolling motor a lot with two Lowrance units and the aerator going all day. Wanting to get all the charge i can when running.

Assuming you have an MD90B, you already have a 280W alternator. Pretty hefty as is, and it's regulated. Neither the MD115, the M115/M120 nor the M140 use the same setup, so they will not interchange.
