The diesel shop came over today and did a flush of the raw water system and when I started the engines after the flush I got the error below. EMGINE/SHIFT STBD Sim No J39 Data then after a 30 seconds or so…. ENGINE/SHIFT STBD Low SeaWater Flow Tech said low seawater flow was just because of the flush process but didn’t comment on the ENGINE/SHIFT. I can shut off the errors and in they seem to come back randomly. Engines start fine, shift fine, and all data seems to be present on the VV and analog gauges. We are leaving Ft Lauderdale on Saturday headed to MD. Headed to the diesel shop first thing. I have to return the rental car at noon. This is stressing me out.
