I have searched and found different answers in reference to timing for the Merc 120. Allot of people are setting it at 6* BTDC. However the mercuiser Manual states 8* BTDC on the 120 and 6* BTDC for the Merc 140.
The dwell range in the Mercruiser manual states 28* - 34* for both. I just...
Got the call today that my motor is not cracked or damaged. The mechanic isolated the motor and put 15psi of preasure on it and checked it two hours later and it still had 15psi.
He said the boat had sat with water in the bilge. He said there is a distinctive high water line that runs along...
I am looking for a replacement Merc 120. I have a chance to get a donor boat with a low hour mercruiser 120. I need to know if it will mate up to a Alpha I. Also, Some say parts for the older 120's are hard to find. What's the difference?
1985 Starcraft Islander Mercruiser 120. I bought this boat recently and took it out yesterday for the first time. The seller of the boat has been up front and honest with me and was surprised what happened. He offered me his email address, home phone number and cell phone number when I bought...
I was wondering if someone had these two manuals in PDF

and
Mercruiser Manual #10 90-14693--1 1985-1989 Engines - GM 4 Cyl
Thanks

The Chriscraft was bought from a widow that said it had been...

I am trying to replace the impeller on my NS40C. I can't figure out how to disconnect the shift linkage. There is not enough play to disconnect the rod at the top. The bottom has pins going through the cable but I am unable to remove those either. The bolt holding the bracket up top is in a...
I am looking at buying a 1991 NS9.9 from a private owner. He says it does not have electronic ignition. If it doesn't have it, can I add it? There are three models NS9.9B which I think is a 4 stroke and NS9.9C andNS9.9D2. I am waiting for him to get back with which model it is. Also, I have...
