Just recently bought my first boat. 20' 1990 Bayliner Capri BR with a Mercruiser 3.0L. The thing takes forever to start up cold. I'm guessing the carbs need a good rebuild since the previous owners never did one. Which one should I buy? Thanks
My 3.0 carb finally needed a rebuild this year after 25 years of good service. I looked at rebuild kits, but by the time I bought a kit, a float and choke(mine needed both replaced), then a can of carb dip, it wasn't a ton more to have a pro rebuild it. Flying Fish did mine. I mailed in off and got it back in about a week. I bolted it on, started it and adjusted the idle mix. It ran great.

Have you tried adjusting the choke?
