This rugged, high-power battery works well in my 2003 Yamaha FX-140 Waverunner. It is more expensive than the lead-acid and AGM batteries I've used in the past, but lasts over twice as long (do the math). It requires some spacers (made from a 1 X 2 trim board) to fit the existing battery tray, but otherwise works fine. This is my second Odyssey PC625. The first one lasted 7 years. I replaced it with a new one just to be safe. I am keeping the old one as a backup because it still holds a charge.
