Yes, that I have, but not paying $180 for a new coil. My question is what color coils from the older engines will work? Is coil color what I look for in a used coil?
The 4HP came out in 1969 or 1970. Phase maker for 4hp was out for 1970 and 1971 only.
The serial number is 3166241.
Dealer confimed it is a 1971 4HP. The Mercury parts system is down right now from cyber attack
Is this coil color information still valid? I am workimg with a black coil with 2K ohms across the +/- and 439 ohms from primary to neg
These engines require the Orange, Red or Green Ignition coils. The Black or Blue ignition coils use a common ground connection internally for the primary and...
Picked up a nice 1970 or 71 4.0 with the Phase maker ignition with no spark. The young lad I bough it from said he replaced the coil.
The coil has no part numbers on it, its black, and the metal tab contacting the neg terminal to the center rod on the coil is twisted. He held it down with...
Hello, I picked up a good 71 4 as a project. Has been sitting and has OEM coils which are shot. I have removed the Mag plate and cleaned and lubed the base plate. All look normal, but when I tighten down the 4 screws that hold it in place it all but freezes up. Can move it but very hard...
Picked up a 9.9HP Chrysler as a project. Plate says model number 92BE, and its Canada made. I am guessing its a 1970 to 1975 vintage, but have not found any way to confirm this. (ignore 8HP in title, was not able to edit)
I have both of these motors. The 87 has a .52 main jet & WMC23 carb. This carb has a bigger venturi than on the 1996 which has a .48 main jet. The 87 is the 12 cu Powerhead and the 96 has the 16 cu inch. The 87 9.9 seems to have more top end speed.
Why would the 95+ 9.9's have a smaller...
I know the 12 cubic inch block has compression relief ports for easy starting, but does the 16 cubic inch also have these? I have a 87 9.9 with 100 PSI compression, and a 96 9.9 with 120 PSI. Could these ports be making the difference?
Anyone bought any std OMC CDI (183-4477) coils lately? Where are they made? I bought a Sierra coil last year and it was from China...Not the best fit I had to cut back the plastic case to make it fit...
Hello, I picked up a 63 5.5 to play around with and cant get it to fire. Has good spark from both coils. I have sprayed quick start in cylinders and carb. (also gas) and nothing. Compression is 90 PSI in both.
Any ideas? Never had this much trouble before, as I have not even got it to...
I am confused by all the different part numbers for the older square style fuel pump.
I found this one on eBay but it says only used by 9.9 and 15hp. I thought all motors from 1966 to 1987 4 - 40 HP used the same pump?
