Hello, my name is***** will assist you.

Was there any other codes that came up at all?

What year is the engine?

SmartCraft Gauges?

Ask Your Own Boat Question
Customer reply replied 2 years ago
Year 2001 no smart craft gauges.
The RPM cut off at 2,500-3,000.
Marine Mechanic: Charles, Marine Mechanic replied 2 years ago

Thanks,

Do you hear the alarm test beep when you turn the key on?

Ask Your Own Boat Question
Customer reply replied 2 years ago
i hear the alarm when i turn the key on. The other codes is #82 oil level sensor high and #94 pitot pressure circuit
Marine Mechanic: Charles, Marine Mechanic replied 2 years ago

Ok, those are all generic codes and nothing to worry about. Do you have a scanner, or a print out of a scan?

Ask Your Own Boat Question
Customer reply replied 2 years ago
i have scanner.
Marine Mechanic: Charles, Marine Mechanic replied 2 years ago

Look at the fault history, see if and when a Neutral overpseed occurred, and if the hour stamp on it was during the last hour of run time.

Customer reply replied 2 years ago
Don't have neutral overspeed
Marine Mechanic: Charles, Marine Mechanic replied 2 years ago

Is there any item of interest in the history?

Does the scanner shoe live data for gear position?

Ask Your Own Boat Question
Customer reply replied 2 years ago
No, only the codes I said. Yes the scanner do live data.
Marine Mechanic: Charles, Marine Mechanic replied 2 years ago

Ok, switch over to live, look at the shift position. Then without starting the engine, shift the handle, you may need to spin the prop slightly to get it to go in. Do this a few times slowly, and make sure that the switch is reacting.

What is your current battery voltage?

Ask Your Own Boat Question
Customer reply replied 2 years ago
I not in the boat right now. But the battery are perfect.
Marine Mechanic: Charles, Marine Mechanic replied 2 years ago

I am going to need to k ow about the switch, and the running voltage on the engine. Both of which can slow the engine down.

Ask Your Own Boat Question
Customer reply replied 2 years ago
Battery voltaje- 12.59
Power 1- 5.01
Customer reply replied 2 years ago
The engine run fine but if we accelerate more at 3,000 rps its do the fail
Marine Mechanic: Charles, Marine Mechanic replied 2 years ago

Is that the stored voltage from the report? Was the engine running then?

the shift switch cuts in between 2500 and 3000 RPM. That is why I need you to test it. Along with that, so does the low oil, and the overheat protection.

Ask Your Own Boat Question
Customer reply replied 2 years ago
That is the storage voltage with the engine off. I need to test the shift swith.
Marine Mechanic: Charles, Marine Mechanic replied 2 years ago

Ok, When do you plan to be at the boat? There are no time limits here.

Ask Your Own Boat Question
Customer reply replied 2 years ago
I go to the boat monday
Marine Mechanic: Charles, Marine Mechanic replied 2 years ago
