Jump Start with Battery Pack

So I know jump starting Sea Doo's can be a bad idea.

I picked up one of these from Costco to keep in my truck or RZR at the desert in case of emergency.

Thoughts on using this in the boat in emergency? 2008 Challenger 180 if that matters.

After going to launch my boat one weekend last year and having a dead battery I also now have a jump pack similar to this that I use when snowmobiling and now boating. Have not had to use it yet but I think it is a great idea to have on board
 
Have a friend who is an avid tournament fisherman... he swears by these things. While a bass boat is a slightly different animal than a Sea-doo, it has never failed him when needed when his starting battery fails him. Its quick and ready.
 
Shouldn’t be an issue I believe. The issue of jump starting with Seadoo products is when you’re running say a vehicle and the alternator bumps up the voltage to 14.5 plus volts if I recall. Don’t quote me on it.

I have one of those packs which has saved me and many other people ATVing and boating.
 
You have been warned that you can fry the computer in these by boosting and jump starting with anything more than a 12V battery. Good luck.
 
Apparently you can fry the ECU or MPEM if you jump with a running vehicle. I bought my boat with a half working ECU (boat running, only some gauges worked) that was apparently from exactly that.
I have jumped my Challenger with a Pontoon battery on the lake. We just made sure the Pontoon engine was off and we removed the jumpers as soon as the Challenger started. Have never had an issue, so I would imagine the same would be true for the jumper.

That is the correct method to do.

I don't know if the it is the volts or the amps of the booster packs but they can fry the computers. I also don't know if it is more common on the older 2-stroke models or not. For me it isn't worth frying an expensive computer and jumper cables are safe and cheap to carry.
