Optimax Power Sensor problem

[richrib]

Hi All, I wonder if anyone can help with a problem I have with my Mariner Optimax 200? It's been a very reliable engine and it was performing perfectly jumping some big waves for about 30 mins in Poole Bay when it suddenly went into safe mode. The warning said 'Battery, Power Sensor'. It limped for a while at low revs (not a nice experience in a big swell!) and would occasionally take more throttle before reverting to low revs again. Having Googled the situation I'm struggling to find any reference to the warning message. Any advice would be appreciated. Richard

I know bugger all about Optimaxs' but could it be a poor battery connection & the engine is going into limp to protect the charging circuitry?

Check all the obvious stuff as suggested tighten all the terminals on the battery and the motor, the ECM usually clears all fault codes after I think 30 mins, have you run it again to see if the fault comes back on the smartcraft ? If it comes back you will need to hook it up to a diagnostic terminal to see where the fault codes are

You might try Iboats. Some good stuff there on engine fault diagnosis.

Ditto Jeff's thought. SERIAL NUMBER first!

If you can't get a 200Hp service manual, the 150 one is available here and should help with troubleshooting - all the electronics are the same.

I had the same symptoms when my alternator started to die.
