Hi guys I have just bought a small bayliner 15ft with a old 70hp merc it wasn't pumping water when i bought it so i replaced water pump and its pooring out now but the engine seems to rev pretty high on the water but doesnt go fast at all seems to be going a lil slower then before i did water pump, i was thinking maybe i connected gear box wrong when i put back together is this possible?

but engines runs fine starts first time every time
