    Confirmation on water pump leaking affecting cool fuel

    The plot thickens. I took the boat out again and it was great the first trip. The second trip it bogged down. I ended up hiring a mobile mechanic to come by and scan my engine. We found the ACTUAL problem. My water pressure sensor went bad so the guardian system kicked in and limited my power to...

    Mercruiser 3.0 unexplained rotational noise

    I'd pull the the prop off completely (1 nut) and start it on the hose. Shift it into drive and see the vibration shows up at low RPM. Perhaps increase the RPM's a bit but not too much as back pressure is your friend. See if it shows up then. I'm no pro but that's where i'd start.

    Confirmation on water pump leaking affecting cool fuel

    Forgot to mention the IAC muffler was super dirty as well. That was the main sucking air sound.

    Confirmation on water pump leaking affecting cool fuel

    UPDATE: PROBLEM SOLVED Hey guys, just wanted to offer an update for anyone whose experienced anything similar. I feel foolish with the fix as it was very simple and very obvious. I took the boat out again after I swapped a new battery in. I pinned it and for the first 15 minutes it ran...

    Confirmation on water pump leaking affecting cool fuel

    The battery I was using was suspect. I had thrown it in right before we went out. I just figured as long as the boat can start, which it did but laggy, the alternator would keep up the voltage to a constant. With that said, if the alternators job is to charge the battery wouldn’t the alternator...

    Confirmation on water pump leaking affecting cool fuel

    Hey gents, I have a 2006 tahoe with a 5.0 mpi mercruiser engine with a bravo drive. In this boat it's got the raw water pump on the engine. I was out yesterday cruising along at 3000rpm, my regular low cruise speed, when suddenly the boat started to slow down and run rough. I backed off the...

    Need help finding an upper yoke input shaft for bravo one

    Hey folks! I just swapped in a new engine coupler in my 2006 5.0mpi with a bravo one drive. When the coupler went it chewed up the input shaft/upper yoke on the drive. I've been looking to replace that shaft but it's proving quite difficult to find one that doesn't cost 500. It's a 17 spline and...

    Advice on Bravo One U joint removal

    Hey Folks! I have a 2006 bravo one drive on my bench right now. I'm replacing the upper 17 spline yoke that couples to the engine coupler. I am having a hell of a time figuring out how to get the caps off the ends off the U joints in order to pull the yoke off. The retainer clips are on the...

    2006 5.0mpi stripped engine coupler

    I'm running a 2006 Tahoe with a mercruiser 5.0 mpi coupled to a bravo 1 outdrive. I was on the water and a buddy got on the wakeboard. I punched it and it seemed like the boat was struggling for fuel. Started to lose speed so I just laid off the throttle. The following day I took some friends...

    keep blowing fuse when running lights come on?

    Hey guys, I have a 2006 Tahoe Q7i and matching Tahoe trailer. My question is this. I have a 4 pin connector from my suv (2011 Mercedes ML350 Bluetech) with a curt trailer module running the lights to the trailer. The trailer has a 5 pin connector on it. I know the last pin is to be hooked up to...

    Anybody used a FLUID DAMPER on their engine before?

    Hey boys, I've got a 1996 4.3L Thunderbolt ignition Gen+ with an alpha one gen 2 drive. I was gonna pull the engine and swap the flywheel because I'm 99% sure it's the wrong one. Gonna sell the boat. It was on there when I bought the boat last year. So in turn I have a vibration at 2500 RPM. I'm...

    Can i tell what flywheel or ring gear i have without removing the engine?

    Hey guys. I have a 1996 4.3 LX gen + thunderbolt 5 mercruiser. I'm still tracking a vibration problem, and am curious about the flywheel. Is there any way I can tell what flywheel is in this thing? I'm curious if somebody put on a V8 flywheel or ring gear instead of the V6 one causing my...

    4.3LX ignition question

    Hey guys, in my quest for a smooth running boat I pose this. I have a 1996 4.3LX gen+ thunderbolt 5. I just did a bit of a tuneup chasing down a mild vibration at 2700rpm. I replaced all plugs,wires,dist cap and rotator "thingy" inside, ignition coil, starter, and slave solenoid. She fires up...
