Excellent Service
by Tim from Gibsons, British Columbia on October 14, 2013
The product, ordering process and tracking were all first class. Ordering from Canada, especially liked the fact that there were no surprise charges when the items were received.

Nice to have functioning charge and tach back
by Tim from Wakefield, Quebec on July 31, 2013
After a year thinking that my tachometer had just stopped working and thinking that I had a short that was draining my battery. It's nice to have a nice new regulator and a battery that charges and a tachometer that works. Hopefully it lasts for a while at this price (compared to regulators for other boat models, not other suppliers).

Merc Regulator
by Don from Jacksonville, Florida on June 12, 2011
I have found after refurbishing my 90 sport jet ignition with CDI products from iboats.com, that these are quality parts, made in USA, and reasonably priced. I have come to trust iboats for all my marine needs.

Q:
I have a 2 wire stator, wanting to replace stator and regulator assy. I noticed on regulator it states to order 174-9610A18 stator but my engine calls for 174-9610K2 stator. The K2 stator picture shows 4 yellow wires, which is the correct part# to order with 194-8736K1 regulator kit? I don't see a way to order the A18 stator, only the K2. Thank you. My serial# is OC110157 Mercury 150 XR-4?
A:
According to CDI the 174-9610K2 is the correct stator. On that stator it shows four wires, but because they are pigtail and come with bullet connectors it essentially narrows down to 2 wires in the installation process. The 194-8736K1 is the correct regulator for your engine as well.


Q:
My Serial number 0C100877. Is your voltage regulator correct for my engine without any changes or adaptations related to stator??
A:
Yes this is the correct stator for your motor as it is a direct cross reference with your OEM number. For installation instructions contact us at the number at the top of the page.


Q:
Does it have a fuse?
