To all the wise insightfull individuals. My Searay (w/3-0lx) has begun to stubble out of the blocks upon acceleration. I have to back off the throttle to stop this coughing action. any suggestions?.

Re: 3.0LX missing on excelleration!

A stumble and/or cough on acceleration is often caused by a lean carb.

First thing I would check is with the engine OFF, remove the air filter/spark arrestor, while looking down the carb throat open the throttle all the way, watch for the accelerator pump squirt.

Was it a steady stream lasting the duration of the throttle movement?

If not then it may be time for a carb kit AND and accelerator pump. Not all carb kits include the accelerator pump plunger, ask your partsman to be sure.

Bondo, CharlieB an others I'm @ this time collecting as much info as possible from last seasons problems with my craft $ tight so research and education are good aids in the off season for an Ohian. But to answer both of you I'll be performing a full tune up plug,wires,fluids,compression & electrical checks,filters and carb rebuild after removing from storage. another service question for all in this thread is it really that difficult to check the impellar on my outdrive (alpha 1 ) along with any other outdrive checks? can i follow my Mercruiser service manual for good sound techniques that are successful?
