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.
