Post GTR 37efi problems
Got a GTR 37efi on a SeaArk mudrunner 180. Runs perfect in the garage, but when it gets a load it spits and sputters. Will eventually get up to speed, but have to baby it to get there. F you just hammer it down it will really sputter. Have changed the plugs and adjusted the valves (3 times to make sure it was right). I wish I could post a video of what it is doing. Anyone have anty similar issues or suggestions? Thanks

Oh, I am in middle GA and can't find anyone to work on it. Not even Sports Center where I bought it

Sounds like low fuel pressure. Start with the basics, check fuel line, fittings etc. check for good flow from the lift pump.
