I'm new to boats, and took my recently purchased used boat/motor up at a shop in Allen to be repaired as it had trouble starting and idleing. After 2 months they found the ECU needed replaced. So the ECU was replaced and I was told all was good and ready to go. I saw it run in the lot with the rabbit ears and it did sound good. Took it out on the water this past weekend and started right up, idle is nice and sounds great in neutral like it could go 50mph, but once in Forward it tops out at 9mph. Found some articles about a wiring harness/pin issue could be the root cause. With that said I don't have a place to work on this and I'm not that good with electrical anyhow. Please can I get a recommendation on a boat/shop Merc 200 efi friendly? as i'm not excited to go back to the shop I had it in. I am located in The Colony area of DFW, but willing to travel to the best suited shop for repair.
