2005 Sea Doo GTX 4-Tec limited knocking noise

[fleiss75]

Sea Doo GTX, 4tec 2005..85 hours.
Has been sitting for months, new plugs, oil change, oil filter and fresh fuel..Making a strange knocking noise at idle in a little higher… Any ideas? I don’t have any errors or codes.. It reaches speeds at 35 miles an hour and the knocking noise goes away, but I can’t get over 35 miles an hour

Is your prop loose? Does the engine hit full rpm but only runs 35 mph?
