Boat issues

[rlm007]

I have a 2008 Supra Launch 22SSV, and during my recent service and winterization, the spark plugs were changed. Today was my first time taking the boat out since then, and I ran into several issues.

Despite fully charged batteries, it was extremely difficult to get the engine started—took quite a bit of effort. Once it was finally running, I drove it a few miles and anchored for a bit. When I went to leave, the boat would crank but wouldn’t start. After about 15–20 minutes of trying, it finally started again, but shortly after, the “Service Required” light came on, the engine began to idle roughly, and it went into limp mode. At the same time, the digital dash completely stopped working, although the rest of the gauges remained functional.

I managed to get the boat back on the trailer, turned it off, and after letting it sit for a minute, it started right up again—but still no digital dash.

Any idea what could be causing this?

After coming out of a winterization, I would check to make sure there not any battery cables got missed. Almost sounds like the low pressure fuel pump may not be working.
