mercury 70hp spark plug wires

[_vn_]

Hi, I got this 1984 70hp mercury outboard 06382231 that i need to replace spark plug wires on.
looking at the serial number i get a part number 812715a1, however this part lists 9" wire - which is not correct length.
when i spoke with mercury they suggested that perhaps wires on my engine are ran in non oem way, but i looked at few videos on youtube and looks like mine are ran same way that others.
my wires are at least 20" long, has anyone had this problem and found a solution?

thanks!

I do not see a 70 hp model listed for 84 year.----Pictures of your motor ?-----Is the model an 0G382231 perhaps ?

here you go, sorry i don't have one with cowling on

I believe your motor is an 83 model.-----You are looking at the wrong parts diagram I believe !

i searched by a serial number, in mercury marine parts catalog

 

[racerone]

What site lists that part # at 9" long ?--------813715A1 might be 9" long.

You have a 1983 model.
That "0" doesn't belong at the front of your serial number, seven digits only.

It is now a cut to length wire, so it fits many models.

Yes - I made my own with Packard 440 wire. It has a copper core and 7MM insulation. BWD also makes 7MM copper core wire. It's less than a buck a foot at your local auto parts store - Check the national AP store sites.

when i tried to search in parts catalog for my serial without 0 in front - search didn't pull up any results, after that i called mercruiser and they told me to put 0 in front of m serial.
and still if you take what you pasted and google it - u will get same 9" cable

there is one more thing left, i spoke with sierra and they have 18-5229-9-1 that might fit

Thats because the Mercury search system only works with newer serial numbers.
