Mercury 200 HP Compression

[jamesbalog]

Mine always gave me a fit first start of the day and then would run fine the rest of the day with just a bump of the key.

Best way I found of the cold start was make sure the bulb was Hard, advance throttle about 1/3 of the way out of gear and start her up. Might take a few turns of the key but once she fired let her sit that way for a minute or so and then I was good to go.

Another thing I learned if I turned both batteries on she always started quicker.

My compression numbers were 125-130 across all 6 before I lost the 1 cylinder
