Ya I think I'd be all over it. Paid more than that for mine? I have a 13 3/4 x 23 'SRX' #390750 (same prop?) Great wheel for top end, but ain't worth squat for much else.
Little bit of finesse required when running one of these. Regardless of trim angle it will blow out coming hard outa the hole. But once ya get it hooked up, hold on. Midrange acceleration is breathtaking.
Your setup oughta swing it. If not raise the motor a hole ...?
