Cmon man, tell us the motors are rowdy and no video?! I want to hear them. 😀 I think that’s the main reason we’re all hooked on these boats. Is the rowdy idle. Glad it went well can’t beat a good day on the water.

Try this. It's my first attempt at YouTube.

Sounds great. looks great too. 👍

Thanks, it ran great up to 71 and then I pulled out of it. I think the AFR was 13 something there. Hopefully pick up some more power with more fuel.

Update...
Earlier I thought I would be responsible and add J-Tubes to my old school Barry Grant (Holley) carbs. I have ran these carbs for 20+ flawless years. These were on my original Merc 420's then on my 600HP 454's before I went Holley EFI. I just put them back on my new Merc 420 builds with 500 EFI cams. I decided to put my handheld AFR gauge on to check my air/fuel ratio. To my surprise I was dangerously lean. 14.5-15.0 AFR. I had to add 6-8 jets larger to get them down to 12.6-12.8. Everything was linear and I only added primary jet 74-76 to 82. I also went from a 6.5PV to a 8.5 PV. I have a bung in every pipe so I have 4 banks and all were consistent. Also picked up 3mph.
