Great Product
by Michael from Yutan, Nebraska on April 25, 2013
My 1992 Mercury 150 XR6 was being very stubborn in starting and would often flood real easy. I replaced the spark plugs like always (every year) but this time not much help. So I ordered the new plug wires (never replaced them before and i bought the engine new in 1992 - 2013 now). I was satisfied with the price and the shipping cost. Low and behold my engine started write up and I am once again a happy boater. My order was filled, shipped and received in a very nominal time which was also nice. I have used before and plan to continue to in the future. Time to go fishing,,,, tight lines....

Will it go on coil properly with the straight boot end part 1998 60 hp merc 3 cyl?
We cross-reference parts using the engine serial number. If you can provide the number we can make sure this is the correct wire for your engine.

Will this wire work for my 77 chrysler 25hp?
If your wires are 7" long this will work.

Will this fit on 1986 v135 black max?
If you wires are 7" this should work. To be sure we would need your engine serial number.

Will this fit a 2003 Mercury Mariner 40hp outboard?
Yes, this is a standard replacement for Mercury 40 horsepower engines.

Need a plug wire for 2000 75hp mercury 4 stroke?
You first need to know length required. So get that and call us at the number at the top of the page with that and a serial number and we can take a look at what we offer.

This is 1 individual wire.

Is this wire like it shows male on the coil side ? and will this wire fit a 150hp V6 2-stroke ?
Yes you will need to just know the length you require.

Can this wire work on a 1989 force. 125 hp model 1251x8c serial serial 3980?
No it will not, it typically is built right into the coil. You need OEM number 888791.
