What I like about that one is it is small and light weight. On a boat, if there is a location available, I would mount a full size battery switch, especially if you have a dual battery setup.

Agree and with this one you really dont need to come up with a dedicated mounting spot if your battery has a lot of room around it, as it would be firmly mounted to the battery itself.

Without me having to look it up, what is the "dreaded code 25"?

It's evidently a knock sensor circuit code. Could be the sensor or ecu. I here it is a ecu issue most of the time. Kind of curious how the ecu develops a issue on just that circuit unless the knock sensors are shorting out internally.

I was telling the battery dealer where I buy all my batteries about putting a switch on my battery in hopes of extending the life of the ecu and he said that it might have the opposite effect, like turning your pc off and rebooting it every time you use it. He thinks that would be harder on it than leaving it hooked up.
Any thoughts on this, now I'm really confused.

Turning off a pc does not hurt it, and actually prolongs the life of the hard drive motor, not that you'll ever wear it out in your lifetime, and actually turning it off clears some of the cache. If that were the case, then every electronic device you own would be failing. Now on to the ecu. lol
Disconnecting the power will prob have the same affect as disconnecting the battery on your car and will reset it to factory settings. A ecu learns over time.
If it's a non fuel injected ski, then there's no issue, and no harm.

Thanks for the reply. I have 2 Honda F12X turbos, an 05 & 07. They are fuel injected, could that be an issue?

It's not that it's an issue as it just resets the ecu. Unless you are experiencing the batteries being discharged while not in use there's no reason to cut power untill they are winterized.

The batteries are not being discharged, I thought it might extend the life of the ecu's, if that's not the case then I agree there's no point in cutting the power.
