I wanted to give a shout out to Mark for his EFI upgrade to my motors. For anyone wanting to change from carb to EFI I would highly recommend this guy! One only needs to talk any of his previous customers to find what a stand up guy he is. This guy is the real thing he gave me a written estimate and if anything changed he would call and ask me for ok. With all the crooks ( and I can name a few ) in the marine industry this guy is a breath of fresh air.. THANKS AGAIN
