Wow, this just hurts so much.

I check every year to make certain that my local fuel suppliers haven't changed their formulas. Once again, for 2011 Cenex (the supplier to the station nearest my lake property) will be using 10% ethanol in their regular gasoline, and zero percent ethanol in their premium gasoline. Their...

Short version: Replace your head temperature sensor. (It's the one on the port side.) Longer version: The port side temperature sensor tells the ECU the engine's temperature. The ECU uses that information to control fuel injector pulse width. (There is also a temperature sensor on the...

...but my wife can't. {grin} We were experimenting with wakeboard handling and I asked her to shorten the rope. She did, then started the engine and sucked the rope right into the jetdrive, not realizing she had drifted over it while making the adjustment. The Spectra towrope was...

We filled two 30+ gallon trash cans with water, yielding ~500 pounds of movable ballast. We also had a topped-off fuel tank. We drove around at various speeds, shifting the weight around and videoing everything. Back at the house, we downloaded the videos so we could do side-by-side comparisons...

As discussed in an earlier thread, I have had an intermittent low-RPM roughness since I first purchased my 2001 C2K with 240EFI engine. I thought I'd resolved it last year when I discovered a failed mechanical wire splice coming off my two-stick console, but the roughness resurfaced this season...

My 96XP got its first good workout last weekend. It would run fine except at WOT, where it would just not get into its higher RPM's. Adding throttle above about halfway had no effect - no bogging, no coughing, just half-throttle performance. Every once in a while the engine would indeed rev up...

That animated Flash banner at the top of every page (the one with the water passing behind the boat) is a real CPU hog. Sitting here on a 2.6GHz machine, one window open (to this forum), not typing, the web browser is hovering around 50% utilization (!!!). Having multiple pages of this site...

One of the modifications I've been planning is some way to suppress the exhaust noise that comes into the passenger area via the floor drain. On my C2K, the starboard exhaust port is pretty close to the scupper valve. Off plane the scupper is still underwater, but once you're on plane (15-17 MPH...

He started a thread a while back about the Mercury M2 jetdrive impeller and wear ring. I'm a newly registered user and the site will not permit me to send private messages, so this is the only method available. AL45, if you still have your old impeller and wear ring, I may be interested in...
