There more than one of his 20,000 + motors that don't run for schitt, even carburated ones. I don't think he understands marine and using the proper cam profile.
MY 2¢

Good Luck

Great looks like im finding out the hard way.I do know of one motor the jack built that was a really good runner.Makes me think he might have subbed out that motor to someone else thats why its a good runner.It sucks but im not even close to finished with him.He will make this right either on his own or in court.If he was smart he would at least send me the $400 cam credit he owes me and $121 for the oil i had to buy because he left his oil sender from his dyno in the motor and the $80 for the fire cord i had to buy because he forgot to give me the one i had already bought.

Oh and jack as you read this i dont want you to think its about the money because its not its because your a d1ck bag. imo

Still waiting for fast to send back my ecu.So with no boat this weekend it gave me some time to clean up more of the mess that jack sent me and it gave me some time to think how jack must feel knowing that he $ucks at what he does for a living.But worst yet this thread has 1500 views so jack that means 1500 other people know how much you $uck at your job.Oh and jack im not going away til you make this right

Interesting....Not picking sides in the matter but I had a motor of his in my old boat and ran awesome every time out and was a real screamer of a motor but also super reliable. Was a carb motor though and from what I can tell if I was looking for an efi motor I would head up to Performance Marine. Have heard of some of Boyd's motors that are really good performers. Keep us posted.
