Impellers replaced last season, about 240 hours.

So, just a quick update as I was able to have her on the water yesterday. Temps in TX down a tad, below 100 at least. Engine temp did not exceed 159, so all good there.

water psi at idle in gear (800rpm) was 6.1 and 7.5 psi. At 3200rpm, water pressure was showing 35psi for both engines. All numbers via SmartCraft Vessel View.

So, seems all good I guess!
