Question
I just bought a boat with 1977 140 outboard Evinrude. When the motor is cranked the motor is flooding out.  Any suggestions.

Answer
Could be a lot of things causing that.  First, make sure you have good plugs and that you are getting spark on all cylinders.  It may be a timing issue.  If the timing on the motor isn't advancing the spark, it will cause it to flood out.  The other common cause is just plugged carbs or bad car adjustments.

Expertise

Basic boat motor mechanics or boat wiring. I can help the most on mercruisers, merc outboards, and johnson evinrude outboards.

Experience

Mercruiser tech. Started working on boat motors three years ago. I have limited shop time under my belt but have proven myself in our shop and am now the shop manager.

Organizations
I have a mercury tech number and a yamaha tech number if you would like, but i don't think that being a certified tech makes you a good diagnostic pro.

Education/Credentials
Three years of see and learn shop time. Two weeks of tech training at Mercuiser school at Springfield. Two update merc schools at Topeka KS. "gotta love George". Tons of "E" skills classes online. Most of my ability to diagnose came from shop time working out problems.
