Hi all. I have learned quite a bit about my boat since my very first posts here. Thanks for the tough love! :)

My question today is, First run this season on my new 5.7L engine. Starts great and we head out. However, for the entire ride of about 60 minutes, if I would full throttle it, it would cut back, hesitate, and force me to accelerate slowly instead. I couldn’t decide if it was flooding or not enough air. I did find upon return, the blower motor was NOT working. Could this be the issue? Bad, warm air? I was also seeing tips on changing out the anti-siphon valve.

All thoughts are welcome here! I’d love to get it running well next weekend. My daughter wants to water ski so bad.

The blower isn't the issue but does need to be fixed for safety.

The antisiphon valve could be the issue or maybe a weak fuel pump
