Boat new to me

I just bought an 03 X10 with 362 hrs. The boat is in great condition ANSI really like it so far. I have a question about the performance. I had a 2000 sky supreme V210 with a TBI 5.7. It was only 270 hp but was about 600 lbs lighter. The X10 had the MCX which I thought would have a lot of power but I am a bit disappointed. My old supreme was way quicker accelerating a would run 48mph. The X10 takes about 1/2 to 3/4 throttle to get onto plane. I guess it s the difference in weight and hull design? It runs 45mph at 5200 rpm. Is this normal or is mine running poor?

Prop will make a big difference

Glad you're liking the new MC.
HP tells only part of the tale when it comes to speed and acceleration for a boat. Prop (as has been mentioned), weight, and hull characteristics (shape and wetted surface) are all factors. All things being equal, HP for HP, the older boats will typically go a bit faster and have more hole shot. But that's why they're great ski boats and not so great wakeboard/surfboard boats.

I had an '03 230VRS (same as X30) with the MCX and with the stock prop it had a very poor holeshot. As others have stated, prop means a lot. What do you have?
Most likely if you switch to an OJ 14.75 X 15.5 you will gain lots of holeshot without hurting top speed. Make sure your engine is tuned-up also. Iridium spark plugs may help too.

I understand that I did not buy the boat for speed just wondering if mine was running ok. Just did plugs and fuel injection cleaner. Motor runs very smooth - I think the tuned port motors have more upper rpm power and less low end. I will see what prop is on it. Has anyone run the new OJ 5 blade on a boat similar to mine?
