Shipping 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.

Not a Timely Delivery
by John from Seattle, Washington on June 12, 2014
I ordered this part six days ago (with two-day delivery) and it has not shipped yet. Also, no emails from IBoats.com about any delays.
