New to boating. No YDS codes; yet port motor still won’t turn over?

[Boatgirl]

So my 2006 AR 230 HO port engine will turn over but will not start. I have cleared all codes on the YDS and ran it again with no codes popping up. However, Port engine is full of oil like all the way to the top even before engine is started. Starboard engine is not that full of oil and is running well. Maybe this has something to do with why the port engine won’t start? Also, how do I know what size engine is in this boat? How can I find that out?

Pull out as much oil as you possible can. Also swap your fuel pumps and see if the issue is still there.

Boat went to shop for diagnosis

 

[k9medic]

Oh no! That can cost a lot of $$ quickly! Your engine should be an MR1. 140hp if I recall

 

[Boatgirl]

I know So far are just getting it diagnosed. That does sound like the correct engine. It has two I believe

If the oil was overfilled it can blow by onto the air filter and starve the engine for air. Check the air filter for oil, and use an oil extractor to pull the oil down to low when its cold.

You can run it without an air filter for short periods....especially on the water as there isn't much dust on the water!

Over filled oil could be an indication of water in your oil. Extract it all, replace the oil filter, replace the plugs. Inspect the oil for water contamination. Make sure your lanier / kill switch key is in place. And attempt to run the engine.

What color was the oil and did it smell like gas. And absolutely inspect the air filter as it is certainly ruined

So the boat ended up in the shop. Needed a new ECM

And the plot thickens.....

Not surprising, we have seen it on the board more than a few times...Injector stuck open by bad ECU, Extra fuel seeps into oil, oil is diluted and overfilled.

Most, (but not all?) cases appear to have a water ingestion issue into the ECU, specially 2003-2006 design were water ingress from the rear falls right on top of the ECUs...

If I had one of these I would be sealing and re-sealing and covering those ECU boxes so if water fell from above they would not go right on top of the ECU.

Sorry to hear and best of Luck!
