Replaced the plugs, cap, rotor all with ACDelco stuff.  The plugs had a paint mark on them, making me think they were original (at 800 hours).  Also replaced all 4 O2 Sensors with Denso ones as my experience with Vortec 5.7s in the auto world is that replacing old (but functional and non coding) O2 sensors will often give an improvement in fuel consumption.

When I pulled the upper intake I noticed the K&N flame arrestor was starting to grow hair and filthy too, so I cleaned it off as best I could for now.

Took the boat out today and it seemed to fire slightly faster on startup.  Ran smooth and seemed good and powerful.  Haven’t surfed with it yet with all the weight/load but what little testing I did it seemed promising.  4 heat cycles so far and I’m still getting the service message and the code remains.  But it seems to run good.  I’ll wait it out for a few weeks.

Depends on how long.   They work great for pretty much everything but if you are looking for your permanent wet slip protection I'd go with something else non inflatable in nature. 

I’ve had babz in a massive storm that destroyed many boats, snapped dock lines, wasn’t pretty. Babz held up perfectly and the boat made it.

Look for the connector along the transom harness wires, or in the port stringer access hole.

 

Thanks!!

Is that yeti a roadie 24? looks like a perfect fit!

The power wedge "leaking" down more than an inch or so, primarily when the engine is started, can be caused by a faulty primary power module, or a harness wiring short circuit.  Remove the wedge down 5 amp fuse from the power module to see if the wedge continues to leak down.  If it doesn't, then the power module is the cause.  If it does, then there are likely damaged or shorted wires going to the wedge actuators.
