Boat Shuts Off

Recommended Posts

dsb87

So we are driving at about 30 MPH and all the sudden - engine shuts off. I look in the back and nothing is leaking and everything seems normal so i shook it off and headed home.

Again were going (slower this time) and again it shuts off. What the heck. I try one more time and again after a minute or 2 it shuts off.

I went to where the batteries and everything are stored and I moved that switch from 1 to 1+2 and i havent had the issue again.

Any ideas what is going on guys. I am by no means a mechanic or an expert in the area of boats.

Thanks for the help!

The boat is a 2014 21 VLX

What was your voltage reading when just running on 1? And what is your voltage reading now when running on 1-2? Sounds like either a bad battery or your alternator was not charging.

This happened to me a month ago on a buddy's boat. Turned out I had hit the kill switch accidentally. Is yours loose at all?

Sounds like a loose connection on the battery switch.

Maybe a defective kill switch

Sounds electrical. Check you kill switch and your canon plug.

I was focused on the voltages and they seemed to remain the same between the 1 and the 1+2.

Where are the kill switch and the canon plug?

Kill switch is by your throttle...canon plug is the connection between the engine and boat wiring harnesses, on my boat it was on the rear starboard side of the engine.

First since changing batteries helped, check all battery connections and voltages. Next check the kill switch, these fail often and randomly cut off the motor. The kill switch is also easily jumped (removed from the curcuit).

Do you have a start button? Those have been going bad too.

^^^ this. Dash button spring was weak on mine... Hit a bump/wave and inertia would cause the boat to cut off

We had the same problem when our VTX was brand new. Turned out to be a bad battery connection. The cables were not installed with enough torque to be tight. What caused the problem was the battery cover, where the cables come out, it pushed down on the cables and loosened them to the point where one came off. The second they came off the engine quit. To fix the issue, I tightened the battery terminals and trimmed the back of the battery covers with U shaped cutouts so the cables can run straight out of the battery. Have not had a problem since.
