I am new to this and very frustrated. A few years ago I started getting parts to build a mini air boat for my son. I’m not into boats or fishing, but like a good project. 12’ aluminum hull with poly, weighs 800 lbs, 4A084 engine, reduction drive, intake, Mikuni carb, headers IVO 64” adjustable prop. I got all the parts from Chuck at Air boat Pros. He’s been very helpful, but haven’t been able to get ahold of him. It took 7 different technicians to find someone to get the carb tuned right. Finally an aviation mechanic got it running like a top, BUT it just won’t Go !! Makes a lot of noise, but doubt it goes 7 mph, won’t run dry land. Goes pretty good on ice. I can set it to run 3,600 rpm, but presently set pitch so it max’s Out at 3,300. It just won’t go. I’ll try to post pics and have a walk around video. I need help. My son and I just want to get it going so we can sell it.
