50 horse Mercury jet only turning 4600 rpms

5600 rpms with it trimmed just right or 5400 with it tucked a little.

Glad you got it figured out. For those that are reading this because they have a similar problem: try 87 octane gas--I heard of a guy that increased his rpms by over 10% by switching to 87 from whatever he had before. Just something to keep in mind.
