    Mid 70's Merc 200 20hp Carb Question

    So I have been struggling with my old merc for a while. I have determined compression is good and spark is good. The motor is still hard to start, surges under load, and will die at full throttle, so I'm not looking again at the fuel system. This has a Type "B" carb with the built in fuel...

    1975 Mercury 200 20 hp powerhead swap

    In an earlier thread, I determined my new-to-me 1975 Mercury 200 (S/N 4148487) was worn out. It had only 60 PSI compression in each of its two cylinders. So, I decided to purchase a powerhead on eBay that claimed 115 PSI on each for $80 + $30 shipping. For posterity, I'm going to document...

    1975 Mercury 200 20hp health question

    I just bought a small boat that came with a 1975 Mercury 200 20hp, serial number 4148487. The previous owner said the carb had been cleaned and the impeller replaced last year, but it was hard to start when cold. Once started, it would start easily. I think it sat for longer than he...

    Oh Buoy!

    1979 Stinger 75 hp Exhaust Adapter

    50's gas cap help

    I have lost the gas cap to my 50's pressurized gas can. There are currently 2 on eBay, but the seller can't give me any information about them other than he claims they are OMC/Johnson/Evinrude. Are these likely to fit my gas can? The pictures look close to what I expect, but I would hate to...

    1955 Fleetwin 7.5 7518 rebuild project

    I have a 1955 Fleetwin 7.5hp that I am resurrecting. It has been in storage for a number of years, became a home to a great many insects, my brother started a rebuild, got distracted, and now I am attempting to get it running again. Wbeaton has been very kind to share a parts manual with me...
