2009 Optimax 115 is in guardian with constant intermittent beeps.
Here's what has happened to come to this point:
In late fall motor was in guardian mode (similar to how it is now). Had boat serviced. Issue was air injector. That was replaced along with water impeller (since it was 3-4 years). Motor was winterized and then stored immediately after.
Took boat out the other day for the first time after winter storage. It was a while before water started to pee, but motor ran great for 2-3 hours. It then went into guardian mode; cant seem to get over 2-3000 rpms.
Also, I was running 2 new humminbird units this year for the first time (not sure if this could be a contributing factor).
After the first trip I charged the batteries overnight, and the next morning started it up again. Motor ran like normal. I let it run for a 5 minutes or so. Turned it off. On again for a few minutes. Off. On again, and trimmed motor up a bit. Motor started to bogg down and went into guardian again with intermittent beeps.
Any help/info or if anyone has experienced similar situation, it'd be appreciated. Will probably take it in to get checked for certain, but any chance at all there might be an easy fix??
