Poor workmanship and quality control
by Dennis from Camarillo, California on March 31, 2015
When I received the solenoid I noticed that a nut on one of the control posts (small post) was cross threaded and screwed down so about two threads were showing above the nut. I installed the solenoid and tried to put the nut on correctly after attaching the wire. The post broke while screwing down the nut. There was just enough left to attach the wire.

Solenoid- and i learned a lessen
by Adam from Auburn, Indiana on June 18, 2012
Your product came quick and worked. Very satified. I made a mistake though. A week later and l honestly was paying attention too who l was ordering from I ordered a ignition for the same boat. (except i ordered from somebody else) Never again!!! I paid extra money for 2 day shipping and never got it for a week!! What was the point of me paying extra money for shipping when they did'nt even ship it for 4 days!!!! NEVER AGAIN!! I bought a prop from you about a year ago and got that quick, lined right up, no problems!! Iboats.com get ALL my business from now on. (and i tear up) hahahaha!!! Thanks Again!!

Poor quality solenoid.. I was only able to use the boat for about 3-4 engine starts
by Eddie from San Jose, California on April 01, 2016
I installed the solenoid on my mercruiser 5.7l engine and it started up just fine. However it went bad after just 4-5 engine starts!! I was able to start it with no issue by jumping it indicating that the battery, starter and key switch were not the issue. The solenoid i had before would occasionally fail and i was hoping that this replacement would solve my problem, however it was a waste of money and time. I will look for a suitable replacement.

iboat's description incorrect
by Donald from Cleveland, Texas on September 17, 2011
This item will not replace the OEM# 89-96054 as stated in the description. The Sierra label on the box does not state it is a replacement for the 89-96054. It is however a replacement for the 89-96054T. These two parts are not interchangeable. I'm sure the Sierra part itself is good as is all Sierra parts I have ordered in the past. Just double check your part number.

Mercury Slave Solenoid
by Gene from Trempealeau, Wisconsin on April 15, 2015
Arrived quickly. Installation was straight forward and fairly easy. The mounting bracket is shorter in length than the original factory solenoid and required a new mounting hole to be drilled. After installation my boat started right away and solenoid works great. I only rated this 4 stars because of the mounting bracket otherwise the rating would be 5 stars. A link to view the dimensions of this product would have been helpful. Overall I enjoy during business with iboats and will continue to do so.

Bad solenoid out of the box
by David from Pittsford, New York on July 19, 2013
Installed the solenoid and engine would not start. Took it to my mechanic who tested it and found that it was faulty right out of the box. Bought a new one at the ship store and had to replace it again. Two hours wasted. My fault though. Should have tested it before I put it in, rather than assuming new part was any good.

defective part
by Alan from Noble, Oklahoma on June 15, 2014
I bought this product only to find out that it was worse than my failing original part. My issue is not that the part was bad but that the return process is so horrible. I called to get return number was forced to do it online, it took 4 days to get a number then another 3-4 to get shipping label info...now 4 days later i am waiting to see if part is going to be covered under warranty to receive a refund. Good thing oriellys was so helpful. I even paid $5 less!! Iboats let me down for the first time!

Works on my alpha one trim pump down
by Shane from Lititz, Pennsylvania on July 27, 2012
Called, and asked for about a down solenoid for an aphla 1 trim pump. The person i talked to said i had to contact the trim pump maker directly. I decided to go by what i saw on the picture and order it online my self. Product works perfectly and fits perfectly. This was on a 1988 wellcraft 192 classic cuddy with a 3.7L mercruiser I/O Alpha One.

2 DEAD IN LESS THAN 1 YEAR
by Gary from Newark, New York on June 02, 2016
I see everyone likes these solenoids as I did when I received them. They are an exact replacement and they do what they are supposed to do BUT they are only good for a short time. I "liked" them so much when I received them that I replaced both the trim solenoids (one was bad and the other was good). That was in August of last year. In April the trim up went and last weekend the trim down went. It's was a good thing I saved the old one when the trim up went but now I'm dead in the water so to speak. For both to go bad is too much of a coincidence. I just went on ebay and bought 2 from a seller that makes their own right here in the great USofA for 10.50 a piece with free shipping. I won't buy Arco anymore so I have to try something new. I hope these last. If you need and buy one of these you better make that 2 because they will fail prematurely so your going to need a spare. Good luck.

Q:
Will it replace 89-850188?
A:
It cross references with 89-850188A1 and 89-850188T1.


Q:
Will this solenoid replace an 89-850187?
A:
No, but we offer the OEM version and we offer an aftermarket from Arco, part number SW097.


Q:
What Solenoid will work on a 1988 60hp Mercury Serial# 0B248178?
A:
You will need part number 18-5817.


Q:
What's the difference between the 18-5816 and 18-5820?
A:
This is a starter solenoid. The 18-5820 is a power trim solenoid.


Q:
On a mercury outboard solenoid does it matter which side is ground?
A:
Sierra confirms you will need to refer to your wiring diagram to be sure. That information is not provided.


Q:
Could this part cause no spark to distributor?
A:
Solenoids are typically a relay to the starter to help crank the engine. Spark usually stems from the ignition system (coil to distributor to spark plugs). You will have to run some tests on the coil, distributor, and/or spark plugs and if you need some guidance you can purchase a repair manual or contact a technician.


Q:
Is there a wiring diagram for this part?
A:
There is no wiring diagram from Sierra. You will need to consult your repair manual. If you need one, you can check what we offer: http://www.iboats.com/Boat-Motor-Repair-Manuals/dm/view_id.1


Q:
Does it come with instructions?
A:
It comes with application info, but not installation instructions. Sierra's tech line would need to be contacted if assistance is needed.


Q:
Will this solenoid fit a 99 mercury 65 jet?
A:
No you will need 18-5834. If you are after the trim relay you will need 18-5849.


Q:
Will this solenoid fit a 1987 mercury 35 power trim?
