Hey guys, Just an update and another question. I FINALLY FOUND THE OTHER PUMP! I was clearing out the boat and there is an access panel under the port side passenger seat. Basically where the co-pilot would sit. Flip that up and there is an access panel. Under that is the pump! It is yellow and black - appears to be a johnson. Wondering if anyone knows if it is a 750 or 1000 gph? I couldn't tell and before I rip it out I want to have the replacement ready to go. I ran out of time and keep this boat at the lakehouse. Can anyone advise? It's a 2007 Centurion Typhoon C4 - 23'. Just posting this update and pictures in case someone else has the same problem! That pump mounted in the engine compartment is the FILL ONLY pump, even though it says reversible! Still working on the V-Drive issue - trying to get a new sensor and will update. Thanks guys!

What is this sensor? There is a dipstick here as well that checks out OK. Let me know when you can. THANKS GUYS!

And that is the transmission, correct?

Is this the V-drive?

Those 2 pumps are the only other ones I can see and they operate the starboard and port ballast tanks.

Hey guys, THANK YOU so much! Pictures are attached of everything. For problem #1, that does make sense having 2 pumps. However I can't see another one, so I'm guessing I will have to pull up the floor panel. Center tank is not easily accessible. I just assumed it was using the reversible option. For Problem #2, I'm assuming one of these is the transmission, and the other is the V-Drive. Please see pics. Thanks! Uploading pics now.

Hey guys, First time post here and I am going crazy trying to figure out 2 problems. I am pulling my hair out! Problem #1 - I have 3 ballast tanks. My center ballast tank is run on a Jabsco reversible pump. It will fill just fine, but was blowing a fuse when flipping the switch to drain. I replaced the fuse and the pump. I thought it was the pump. It will fill just fine, but when I click it to drain, I get nothing. No power, no noise, nothing. The tank is full and I can't drain it. Also, when I flip it to "fill", water is coming out of 2 holes on the side of the boat. I know 1 is an overflow and that is normal when it is full, but why is it coming out of 2. Any advice? I really don't want to take this to the dealer for the stupid ballast pump. Problem #2 - My red V-drive light on the boat is random. When I go to start the boat, it comes on when the key is turned to the "on" position. When I actually start the boat, it goes off. It stays off and then will randomly come on at about 3,000 RPM's, but only sometimes. This is around 24mph. Then when I back off the throttle, the light goes off. After riding for a bit, it will come back on again. It is random. Oil level looks good and oil is clean. I checked the oil in 1 spot. Is there another area I need to check the oil? It appears this is a PCM V-drive. Any help on these would be great. I am somewhat mechanically inclined and would like to avoid a dealer if I could. Thanks so much!
