2010 Sea Ray Sundancer 240 (240DA / Mercruiser 5.0 MPI)

Just purchased boat with 89hrs (2010), prior it wasn't used much, and stored on a lift, above-water.


Had some trouble planing (trim tabs, and I/O trim are sensitive on these).

After 5 minutes on-plane:
- O2 sensor started beeping
- Water Pressure shows "0" on gauge
- engine throttled back, and only allows Idling (500RPMs) and won't allow acceleration (returns to idle, and goes into engine safe mode)
