First time out with new boat

Took our new 22SSV Supra out today for the first time. Threw her in the water. Turned the engine on and tons of water started coming in. I turned the engine off and found the front hose off. After getting it tight, I turned her over and again, water started coming in. Found the rear hose. Didn't put it together at the time, but later realized the boat wasn't de-winterized like I was told. Winterizing is new to me as our old boat we kept in the water year round (salt water boat). Put two of the break in hours on her and loved every minute of it. Weather was 70 degrees and sunny (great for Seattle area right now). The boat purred. Can't wait to get behind it for a tow.
