[Bass_Appeal]

as most are aware i got my new yamaha 300, on way home from atlantic highlands i had to go slow for break in reasons , im at 5 hrs now and they told me i could start running normally except for wide open , any way when i get up in speed the boat starts to list to the left pretty bad ! what can it be ? can it be prop pitch ? the way im trimming ? i have trim tabs but thats beside the point , prior to i didnt list
