An additional item to consider. A Yamaha 2.5 HP has no reverse gear. You have to swivel the engine around backwards to go in reverse. This would be particularly difficult if you lowered the motor. It is, in fact way too small for your boat. I had one on a Compac 16 and it was ok but not for any larger displacement boat.
However, it is a very desirable motor for small sailboats, fishing boats, etc. It should be easy to sell or trade for an older 6 or 7.5 hp longshaft motor in good condition.
