I bought an 06 Avalanche with a Black Scorpion 6.2 with really low time (230hrs) that looked like it had been taken care of, but it wasn’t. The latest issue is, the sea pump will not pump. After destroying a couple of impellers I finally checked the cooling lines and found an insane amount of broken impeller pieces in the tranny cooler. The boat had a new impeller in it (should have been a red flag) so I have no idea if more material is downstream or if anything can even get downstream. My question is can anything actually get passed the tranny cooler? I can now push water with a garden hose from the pump all the through the exhaust, so I’m wondering if I’m ok or I need to check the thermostat housing? Also, giving up on the original sea pump and replacing with a Harding SS. Sorry for the really dumb questions, but I cant find anyone in Arizona in the boat business that has an IQ greater than a pine cone. The previous owner is completely worthless, not sure how he managed to get it off the trailer.

Your 2014 SV233 needs a water filter!
byerman posted a topic in Centurion Boat Maintenance, Performance, Troubleshooting
My 2014 SV233 pulled up debris from lake Powell and the impeller quit working. We pulled large amounts of small wood debris out of a heat transfer area on the lower starboard side of the engine. There is no pre-installed water filter on the boat! I had a local dealership change the impeller and put a filter in the intake hose where it is easy to clean. Shouldn't this filter have already been installed? If yours does not have it, consider installing one ASAP. Save your trip before it is ruined. -
I have a 2010 Enzo 240SV and the engine fluctuates between 175 and 185 when I'm cruising at 11MPH (RPM's between 3200 and 3350) with a full load of ballast. When my surfer falls and I'm idling, my temperature can creep up to 195 - 200 or even more. Sometimes the engine failure light comes on, and it's generally because the engine is going over 200. What is the typical temperature fluctuation with an Enzo? What is normal/target temperature? What is the hottest I can let the engine go up to? By the way, I had my impeller replaced at the end of last year...and the mechanic looked at it at the beginning of the year and said I don't need a new one. Any ideas? Thanks. Don

Belt squeal, overheat, alarm. Help!
kylesullens posted a topic in Centurion Boat Maintenance, Performance, Troubleshooting
All summer, I would hear the loud squeal of a slipping belt. Slight increase in engine temp. If I throttled down then back up, the squealing stopped and temp returned to normal. Somewhat annoying, but didn't occur enough to stop our boating fun. Verified that it was the impeller pulley that was preventing the belt from turning. The other day, the squeal started and did not stop. Alarms sounded for engine overheat as the temp climbed to 220+. this happened several times in a 2 hour outing. read all the posts that I could find on this forum, and they all indicate a bad impeller. Bought a new (Mercruiser, not seirra) impeller and housing, and a new serpentine belt. Installed all parts and tested in the driveway (on a fake-a-lake). Worked fine for a couple of minutes, but then the loud, continued squeal. Took off the belt, and the impeller was stuck again. Was able to turn it by hand (very difficult) then it freed up. It seems that the impeller is getting 'flipped' in the housing - meaning that the fins get curled in the wrong direction and the tension on the belt is not enough to turn the pulley with enough force to 'flip' the fins in the rights direction. Though the belt is on as tight as it should be. Not sure what else to do. Don't want to take it to a shop, because they will just recommend replacing the impeller. Any experience or suggestions are appreciated! '99 Centurion Elite V-Drive, Black Scorpioin
