Idle Problem

[ROADRASH]

I'm brand new today...first post but visiting for two years.I have a carbureted 2005 20i which I bought used with low hours two years ago. Had idle problems from the onset which I attributed to stale fuel, etc. Engaging the velvet would kill the motor 4 times out of 5...made docking pretty exciting. During my fall fake-a-lake mothballing I bumped the velvet into gear for a second and heard an immediate squeal from the prop shaft bearing. Took it to the dealer who replaced the notorious 05 only ceramic bearing under extended warranty...I was impressed. However they admit that they were unable to cure the stalling. Has anyone else experienced this? Dealer blames carb but can't find anything physically wrong with it. I set the idle speed up and that helped, but makes me come into the dock too hot which is even worse if it stalls...hull killer. This is my 11th boat since 1971...4th inboard ...don't think it's operator related. Any help out there will be greatly appreciated!

Welcome to the site! Unfortunately, I don't have any answers for you. My boat is fuel injected.
I hope this bump will get you some answers.
Did you try all the other tune up stuff? Filters, plugs, cap and rotor?

Carberated boats are a rare thing these days. Not too many of us even remember how to work on a carb anymore. What kind of carb is on it? Do you change a lot of elevation when you go from home to the lake?

Welcome to the site. I don't have any advise for you but would like to see some pictures of your boat. Good luck on getting you problem solved.

My gut says its time for a carb rebuild.

I'd agree with Mike, above, but before going the rebuild route, i'd try a few treatments (ie seafoam).

Don't know what's going on with the engine. But you should never engage the transmission while out of the water.

Zad is correct. I made a similar mistake when I bought mine.
