Need new power

New member here.



It was out on Saint Patty's Day and



Lost the motor.



Looking for some advice on a new motor.



I have a 28 foot silhouette deck boat.



That had a mercruiser 502.



With a Bravo one outdrive.



Would like to upgrade to at least 800 horsepower?



Maybe a blower.



I know I've gotta do hydraulic steering and probably



A closed cooling system.



Any



Thoughts comments or concerns.



I live in Concord.



Any help would be greatly appreciated.
