List of things NOT to do to your Jet Boat...

[Coastiejoe]

When a 4-tech engine turns off, every valve is in a the closed position. However, the water from either a garden hose and it a tow will film the exhaust then the top of the head. As soon as you crank the engine, the standing water is sucked into the cylinders.

So does this mean you can still jump the boat with a car if the car isn't running??

Ok I did some more digging, but it goes like this, it looks like you could jump the battery from a "non running car.. In other words the car or truck is not on".. You could fry the MPEM

Here is some more info I found on google:

Anything over 2.5 amps can cause harm to the MPEM. From what I have read, getting to the boat batteries is no fun. I recommend installing a remote battery switch that is easy to get to using two quality battery cables and a shut off switch.

This would allow you to turn off the batter and charge it with a regular higher amp charger if you wanted to..

So would this be a problem being that it's 8A?
