Hey guys ! So first time in the water yesterday and my 351 is bogging under load . It's like almost a air leak or loading fuel .

My questions : carb rebuild kit ? Fuel pump ? How is the fuel flow test measured ?

I always thought to check the fuel pump you pump in a bottle but how to measure it ? How long it takes to fill up ?
The carb hasn't been rebuilt since I had it but it ran fine last year so idk


Basically I just need some advice on diag and if anybody else has had the issues . It runs fine idling and can rev up with no hesitation just if you are underway and say just throttle to 2k rpm and maintain that speed it will bog out and almost die about 1 min later
