I think I just fragged my 150 Yamaha

The first thing I do when I get new batteries is mark the + and — with a white paint pen.

Glad you got it going

Phew that was a close one I bet that is never going to happen again and one good thing is that you brought attention to that and first thing I’m going to do is mark my terminals.

awesome, glad you were able to figure it out and it was only a cheap fuse.

Great. Easy fix. We all make mistakes.

At least this mistake only cost me $5.00 and I have 4 fuses left for future mistakes! Haha.... Again thanks for the help and support.

No problem. There's a couple guys on here that really know boat stuff.
Not me. I'm mechanical but new to boats. Learn as much as u can from others.
