Help - Mercury Control Box?

[Stacer560]

Gents,

I have a 90 mercury saltwater series 2stroke 2003

After been busy for 3 weeks, i finally decided to give my boat a start up and let it run for a good 15mins to clear out any cob webs ready for summer.

Starting the engine was easy, and it rumbled as it always does. I let it idle for a good 10 minutes to let it warm up.

Then i decided to lift the lever to give it more throttle for zip and the max i got to was 1500rpm.

Then i gove it some forward motion, prop began to spin, but again no more than 1500rpm.

Now i am hoping it is some from the forwad control box.

Any one had this issue, and is sit an easy fix?

Or am i looking at a new forward control box??

Your help would be great. Any theings i can try to see if i can get it going again?

Stacer, the first thing to do is to check the throttle cable both ends, firstly under the engine cowl to ensure that it hasn't slipped out of the connection. Get someone to operate the lever on the control box while you look at the engine end of the cable to ensure correct operation. If that is ok then do the same check at the control box to again ensure that it hasn't slipped or partially disconnected. If the cable operation is spot - on then you may have to dig deeper to determine the problem, perhaps with the carbies. As with any troubleshooting, eliminate the easiest things first before panicking.

Hi Stacer560, I have the 2003 90 merc.

after you check all connections and linkages,if it still does not rev out

give huey a ring.when you lift throttle lever you should red line it.

Cheers Rick.
