I have twin 2015 Merc 8.1 horizons in my 97 Searay 330 EC.

When i run at higher RPMs over 25k the port engine throws up a code in Smart craft. 1052-6 Crankshaft or camshaft trigger the device , calculation or process detected a fault.
fault

The engine runs fine and if I lower the RPMs back under 30k it disappears.

The image is from the Smart craft app on my phone. I can seem to read the code in the inboardinboard gage.

My mechanic said to ignore it but that does not sound right. Any advice great appreciated.

Life on the water is always better.
