Mercruiser 3.0 L Alpha One - "stalls"

[CntrySngr]

Wondering if someone can help me. When I start my motor up from a cold start it has a tendency to "stall" when I go to move from No-Wake to WOT...there is a spot in there it will stall. Once the motor has been running for a while, it doesn't have that problem. Any ideas?<br /><br />Also, I noticed last night that it seemed like it wasn't starting as quickly as when I bought it and started using it a few weeks ago. I had to turn the engine over for a while longer than "normal" for it to start. Granted, this was after I forgot to put the "kill safety switch" and strap back on. Maybe it was flooded?

I find that on my 3.0l it stumbles the first time I give it the juice. On the first time, I just ease it up onto plane instead of goosing it and that takes care of it.. It isn't enough of a nuisance for me to look for the cause which is probably the accelerator pump on the carb. Others have pointed this out but, like I said, it hasn't been a problem enough to fix.<br /><br />Flooding should only affect your engine until the engine clears itself after it starts. when I cold start mine, I put it in neutral mode and pump the throttle a couple times and then leave the throttle at about 1/3 before I start it. It usually pops right off. Of course then I back it off before it revs too high.<br /><br />You might try this type of routine if the problem persists.

its never going to run like your car we were spoiled but EFI<br /><br />the question becomes how long is a while ? my 1995 3.0 will run stall free after about a 90 seconds<br /><br /> you have to pump the gas a couple of times everytime you start it and usally have to give it a least 1/3 throttel in netural and let it warm up at about 1500 RPM <br /><br />a so so battery will turn it over so so<br /><br />a battery place can load test it to check it<br /><br />i bought a new battery last year and it cranks over a LOT faster the old on held 12.3 volts but really could not put out the amps anymore<br /><br /><br />tommays

When was the last time it had a full tuneup. Unlike cars and trucks, a yearly tuneup is needed to keep them working properly. That also includes timing adjustment and carb adjustment.
