ZR409 oil change
Jlagos replied to InfinitySurf's topic in Centurion Boat Maintenance, Performance, Troubleshooting
Interesting you say that. The 1st time I changed the oil had the same problem. No oil came out despite lowering the hose as low as possible. Inserted extractor tube and again nothing. I had my son turn on the engine for about 2 seconds and the oil easily drained out. No problems since. I have placed a female thread on the extractor hose which screws onto the engine drain hose and not a drop of oil gets spilt. Some people are able to thread the drain hose through the hull plug opening. Didn't work with my boat. No other valve or cap to open. -
Cracked unknown part from the water system identification
Jlagos replied to Mule's topic in Centurion Boat Maintenance, Performance, Troubleshooting
Did not know that. I wish my 409 had blue plugs. -
Cracked unknown part from the water system identification
Jlagos replied to Mule's topic in Centurion Boat Maintenance, Performance, Troubleshooting
Considering you have blue drain plugs I assume you have a mercruiser black scorpion engine? Also I assume the stern is to the left of picture. If above are correct I would guess a recirculating pump or raw water pump. -

Great boat. Welcome to the site. -
Port exhaust manifold much hotter than starboard: 330 Black Scorpion – 07 Elite C4 Air Warrior
Jlagos replied to King Eric's topic in Centurion Boat Maintenance, Performance, Troubleshooting
Exhaust manifolds and risers can at times corrode in as soon as 10 years. I would guess that the water jacket (the holes within the exhaust manifold) that carries the water prior to dumping out exhaust is starting to fail. Theoretically not difficult to change and easily accessible. Typically 4 bolts to unscrew however they are often stubborn or unwilling to remove. If this is your problem, change both sides as they are both likely ready to fail. Hopefully others chime in to correct or confirm my suspicions.- 2 replies

Water in Cylinders
Jlagos replied to byerman's topic in Centurion Boat Maintenance, Performance, Troubleshooting
On an older boat I would be concerned about the risers corroding over time but I would be surprised if this was happening in yours. What year is your boat? I would be inclined to think the head gasket is the problem. The overheating may have weakened the gasket.To check can do a compression check on all cylinders. If defective you'll find a cylinder(s) that have lower compression than the others. You may have to pull the cylinder head and inspect the head and block for cracks. I would bet on the gasket. -

Turning Boats over every two years
Jlagos replied to Carter13's topic in Centurion Boats General Discussion
I have not been lucky enough to see a 7. Have you? They are a sweet. They sound cool as hell in the videos I've seen. -
Awesome waves on both boats. David I guess you now need to change your profile to reflect the new boat!

Let's Revisit Batteries
Jlagos replied to Shaka's topic in Centurion Boat Maintenance, Performance, Troubleshooting
I'm sure others will pipe in who know alot more than I but if i prefer to select the battery for the specific purpose. Cranking to start the engine, and a deep cycle for the radio and accessories when floating. I would imagine the deep cycle, as opposed to dual purpose, is able to tolerate the constant discharge/charge cycles better having thicker plates. Do your batteries sit sometimes in a partially discharged state or do you completely discharge your batteries prior to recharging? Both scenarios will kill batteries more quickly. I get the deep cycle with the highest Reserve capacity I can find locally. I have heard the Duracell batteries at Sam's are made by a very good brand (can't remember which manufacturer). I have thus far just purchased the flooded and have had pretty good results. I too do not have a huge sound system that requires multiple batteries and am often moving when on the water. Not sure why your batteries are lasting only 1.5 years I would have thought longer. -
Surge Brakes Locked
Jlagos replied to Shaggs's topic in Centurion Boat Maintenance, Performance, Troubleshooting
Dr. Nate, I had the same thing occur this weekend. Disc brakes on my trailer (surge not electric). I trailered about 1.5 miles and thought the trailer felt heavier than normal. Got to boat ramp and the brakes sizzled as I backed up into the water (crap!). Do you recall your problem and fix. -
"Power plus" v-drive trans....change fluid?
Jlagos replied to InfinitySurf's topic in Centurion Boats General Discussion
Your going to need to find Chevron/Havoline. Apparently PCM does not want a synthetic product in the unit. From what I've read that is what the technicians recommend. Havoline Automatic Transmission Fluid MD-3 Havoline® Automatic Transmission Fluid MD-3 is formulated for applications that call for the former DEXRON®-III H, MERCON®, and Allison C-4 fluids. -

"Power plus" v-drive trans....change fluid?
Jlagos replied to InfinitySurf's topic in Centurion Boats General Discussion
Yes, insert fluid extractor tube down dipstick whole and remove. Small funnel is much needed when refilling. I can't remember seeing any boat threads ever talking about filters.
