It's me again. I have my first boat. Which I thought ran great. when I went to buy it. Heard it and didn't sound bad. However 2 months and 3 trips later i only get about 100 yards from dock to turn around and bring it back home to work some more. First time out found out it was only running on 2 cylinders so me and my GFS dad brought it home, bought new plugs n started it up. Sounded great at idle took it back out and same deal only running on 2 cylinders. His friend brought his spark tester and we found it wasnt firing on 1 & 4. So I ordered used coils off of eBay that were guaranteed.(don't want to buy new ones and lose money if it wasn't the problem.) They work. Now fires on all 4 cylinders. Sounds awesome in driveway hooked to water however, yesterday 3rd time is a charm right?! Nope! She wants to run. She wants to run bad hit the throttle and she lifts up like she's about to haul a** and drops back down. Maybe 15 mph. Top speed. She starts to want to go and just won't. You can hear it chugging. If I hit the choke it seems also like it's about to get up and go and does give it a bit more for a split second. It's new gas in marine fuel cans. (not using boat fuel tank) bulb stays pretty firm. I havent cleaned the carbs yet. I'm lost. Any suggestions will be used. I can post a YouTube video if needed but don't know if it will help. Thank you
