Marine EZ-EFI / Edelbrock Pro-Flo XT Tunnel Ram installation

MR Marine in Spring Lake, MI uses our EZ-EFI tunnel ram kits to convert twin big block chevy mercruiser engines to fuel injection.  According to Mark, the install was straightfoward and trouble free.  (it looks to me as if you’d have to stand on your head for a few hours, but Mark doesn’t seem to mind) Setup and tuning was straightforward and very effective. Start up was immediate. Our kits use Edelbrock Pro-Flow tunnel rams and throttle bodies, and FAST EZ-EFI controllers and electronics for excellent power and reliabilty.

The boat owner has been very pleased, fuel economy has significantly improved over the Mercruiser carb setup,  and throttle response and mid range torque are much improved as well. Definitely a plus when getting a big boat moving.  In fact, the owner of the boat originally ordered a single system to compare the fuel consumption and power for an entire season before purchasing the second kit. He was so pleased with the result, he ordered the second kit in about a month!!  Congrats to MR Marine on a super clean install and a happy customer. Great job guys.
