Full StarEmpty StarEmpty StarEmpty StarEmpty StarShipping Service
by John from Grand Rapids, Michigan on June 23, 2016
Ordered two Sierra 18-5438 ignition coils on Monday June 20th and paid additional money for 2 day service so I would have them before Friday. iboats billed my PayPal account on June 20th for the full amount. I just checked today, Thursday June 23 and iboats could not confirm if they had shipped yet. They gave me an excuse that maybe Sierra did not have them in stock. This is a standard ignition coil for all 454 mercury engines. So far I rate their service well below what I would expect for an online company. What a waste of money on my part. Before ordering I would suggest you call them to get an exact ship date. Bad company.

Q:
Can this be used to replace 3854002 looking for performance ignition coil?
A:
No.
Q:
Can you provide the ohm rating of the internal resistor?
A:
The primary resistant ohm rating is 2.7-3.36.
Q:
Is it compatible with Volvo Penta AQ260?
A:
No it is not.
Q:
Will this work for volvo AQ131A engine?
A:
No this will not. You will need 18-5436.
Q:
How many ohms internal resistance does the coil have?
A:
The technicians at Sierra have said that it is an external resistance coil, and that it has no internal ohm resistance. If you have any further questions contact us at the number at the top of the page.
Q:
My 1985 3.0 mercruiser does not have an external resistor, is this the right coil?
A:
The technicians at Sierra have affirmed that all of the 3.0 Mercruiser engines from that year should have an external resistor. If yours does not, then you will want to consult a Mercury dealer for guidance on what to get. Because all of the information we have on this motor points to this ignition coil working for it.
Q:
Is this the right coil for a 1996 ,4.3 v6 190 hp?
A:
Since it is an aftermarket part the way we cross reference varies. We would need to know manufacturer and model/serial number. Contact us at the number at the top of the page and we can look into it further.
Q:
I have a 1977 mercruiser 151 cu in. 120hp 4 cylinder engine. It does not have any resister between the distributor and the coil, therefore, I must have a resitor wire and not an external resistor. Is this the right coil for this application.?
A:
No this would not be correct. This is for an external resistor. We would need serial number to identify correct one at this point. Contact us at the number at the top of the page and we can look into it.
Q:
Is there an HEI version ?
A:
We sell aftermarket parts and this is the only version Sierra makes for this engine.
