I have been told that gasoline with up to 9% ethanol can be labeled "ethanol-free". Once it hits 10%, it has to be disclosed. Can anyone confirm or deny? Hate to pay extra for ethanol- free if it is actually only 91%. I have used Sta-Bil Marine formula in my waverunners for years and started...

Put in new Mercruiser fuel filter with rebuilt Mercarb (807312, electric choke, from Guaranteed Carburetors in Largo, FL) two months ago. I will check fuel vent. Without looking up in manual could someone tell me where it is? Hope it's something that simple, Cliff's trouble-shooting process is...

Thought my engine dying at low idle may be a carb problem so I installed a fully-reman'd 2-barrel mercarb and new plugs and still dies. Also had trouble in past re-starting when warmed up. It now has to sit about an hour to start again. Had to shut off to gas up at Marina. Of course, it...

Two barrel carb, no tag only numbers stamped in as follows: 807312 6903 Looks like a mercarb, mine has a zip tie on upper linkage, yikes guess I'll get a reman'd for $300 vs kit with brass float for $60 the zip tie makes me uncomfortable

Conditions making me think rebuild: I get hesitation when throttle up to pop up a skier. Motor dies as I shift from reverse to forward when pulling out of dock (after sufficiently warmed up) Motor also dies when shift from forward to reverse when docking. Must then stop a coasting 24 foot boat...

Good Day All, Purchased a '97 240 Sundeck about 16 months ago. Boat is stored 2 hours away. Was wanting to rebuild carb but not sure what kit to get for my 5.7 liter with Thunderbolt V ignition. Only one carb available for this boat or do I have to trek over to get numbers off carb...

If I heard the noise upon first acquiring the boat last year, I probably wouldn't be concerned with it. "Whir" only surfaced a month ago.

Thanks for the reply Cliff. The noise I'm hearing may better be described as a "whir" rather than a "whine". I hear it much more at low rpm's. I suspect that the engine noise drowns it out as the rpm's increase. Mainstream, I was thinking catastrophic failure would mean no prop spin and a tow...

97 SD240 with Alpha One outdrive (SE 116) had boat for year and a half. Couple weeks ago I start to hear what I can best describe as a gear whine from the outdrive. No such noise when rev in neutral. Thinking may be gear oil contamination or just low I change out, adding to reservoir next to...

Now we're going up and down! Electric motor repair shop wired up drum switch and motor and showed me it worked both ways. Left only the wiring to be the problem. Replaced my 5 conductor wire and it runs like a champ. Don't understand why though as I switched wires all over the motor and switch...

Seems saga not over. I posted after watching my sundeck rise out of the water for the first time in two weeks only to find out later that it trips the circuit breaker immediately upon trying to lower the boat. Obviously still have some work to do.

Happy Ending! Took 3/4 hp AO Smith motor and lift switch to electric motor repair shop that has worked for me in past. Cleaned dirt caked motor, mud daubers loved it in there, wired up and everything checked out fine. Just installed this morning and lift works like a champ. My cost was $48...

Single motor on my lift Going back to lake Friday. I'll try the hammer tap and get a voltage reading at motor. If still non-functional will remove motor and drum switch and take to repair shop I know where I live. They've been repairing electric motors for forty years and don't think the motor...

Been lurking for a year now since I bought my 97 240 Sundeck. Pulled into slip Saturday, raised lift enough to hold boat stationary, let my passengers off, then tried to lift out of water and the motor just hummed. Won't go up or down. Both pulleys and the belt will turn by hand. AO Smith 3/4...
