Sorry for going off topic here...
You're looking at a HUGE size sib, assemble, inflate time not to mention the weight, is directly proportional to lenght, width and tube size. Get a electric pump or a high flow kite/ paddle board hand pump to make your boating life easier while inflating. The 14" footer is rated for max 40 HP engines to have fun while boating with full stated load or passengers capacity, much less with 30 HP though not to mention 18 or 9.8 engines.
Assuming will get on plane with a 9.8 is a wild guess. Will depend entirely if having tubes/keel top psi inflated, correct leg/transom height match & trim setting, well distributed load, outing with minimum passengers and riding on flat calm, windy, choppy sea conditions. Worst scenario, just fast displacement speeds.
Don't buy the air deck 14" footer model, that model needs a heavy duty air deck for top rigidity and it's just being delivered with a standard air deck. A 2 strokes 18 HP engine would be ideal, right in middle 9.8 and 30.
Happy Boating
