So I just had my 1 st problem with mine that turned out to be something very simple . About 2 two weeks ago I was rolling into weigh in as I got to 4600rpms the motor just shut off . It restarted right up got back on plane starting get back up to speed once I got 4600 rpms motor shut down again . It did it 4 times in 15 miles . I am very blessed that one of my best friends is one of the best outbroad mech. He met me at the river at the house a week later hooked up his computer to the motor and we took off . The motor did the same thing another 4 times . He did a multiple of different test trying to figure it out . So he took it back to his shop hooked it back up to the computer and the Dyno this time he recorded all the electrical reading . He noticed there was a one volt drop it would be running at 14.2 volts and as soon as he pushed over 4600 rpms in a Milla second the voltage dropped to 13.2 that’s when the motor died even though the voltage came right back to normal . So He called Yamaha’s tech service talked to them they were convinced it was the main computer. Yamaha sent him a new computer he hooked it up and the motor did it again . He called Yamaha again this time he talked to the main tech . He said he was 99.9% positive it’s a lose battery connection. Sure enough that’s what it was the main wiring that attach in side the motor were not lose but not tight enough he said it was maybe a 1/4 turn lose . Guys add this to your regular maintenance Check on your SHO motors . Might save you some grief . Mine will be checked every year now when doing oil changes .
