Engine won’t turn over

[Erodvrx]

Hello I have a two twin 255 Rotax engine and I went to the boat ramp and both engines wouldn’t turn over. I started to hit the dead man switch and they both fired up. But after about a month of it sitting the lcd panel turns on but both engines won’t turn over . The battery are both good . I also checked the dead man switch and it was fine.

I would start checking fuses and relays. Inspect everyone. There is one relay which has been discussed here that might just be the culprit. Check this out: https://jetboaters.net/threads/rotax-owners-keep-this-handy.13017/

I had the same issue a couple months back. I don't have an exact answer, but I did pull/inspect most of the fuses/relays and all battery cables, etc. Everything checked out fine. After that, the engines fired up and I have not had any starting issues since.

Hello guys I had two bad relays . One on the port side and one on the star board side. Thanks Dean P
