150 etec only idles

[champ]

The boat started right up and got it ready for launch. Once I launched, I put it in gear to go and nothing. It only idled. It kicked into gear but the rpm's would not go past idle. Almost like the computer or something was stopping it. Managed to idle to my slip but could not back it in, had to manhandle it in.

Ran fine when I pulled it out.

Any ideas?

Thanks
