Hi Jeff,
As requested to keep you updated, been awhile I had the chance to get things done and get on the water.
Charged both batteries on the new MXS5.0 and boat start fine again with no issues, haven't got any replacement battery yet. When the time comes for a good sale then i'll look at my option.
Thanks for the update on the sale, I found out too late with your post.
Cheers Victor.
