Looks like a Black Max
 

I just bought this boat around Lake Erie. Took it for a ride and the Boat Came out of the water no problem, Speed was great, Everything was great! Now .. Here comes the dummy. I take the boat down to Pleasant Hill here in Ohio.. Had a real bad day. Forgot Keys, Storm coming , and My boat bottomed out and the prop has all kinds of nicks on it and a piece the size of your thumb completely missing. I didn't find this out until 30 mins later after taking the boat out. Now i did have some weight in the boat. But i could not get the thing to Plane up. I felt like the thing was going to flip over. I adjusted the Trim tabs and they just didn't seem to help at all! I am new to the bigger boats. But i just had this thing up at Lake Erie and had now problems. Now i am. I can post a pick of the Prop here. I just don't know where to start.

Mariah Davanti 215
WOT 4200-4600
Top speed i had it up to at lake Erie was around 44
It looks like a Black Max aluminum
My books and manuals here are showing i have a 19 Degree pitch. Diameter I do not know how to determine. I fell like i have read all of the helpful links in the sticky but can decide what to do or where to start. Any Help would be much appreciated.

To add to this problem.. when i was on plane, the engine seemed like the clutch was going bad. I dont know what that means in boat terms. Maybe Slipping? Could my trim be too high.There was not much of any wake on the lake at the time.

Sounds like you damaged the prop to the point it is well out of balance and you have spun the hub in the process. Check your trim tabs too to see if you damaged one of them.

I'll take the prop off and take a look at how to adjust the Hub. Thanks!
Should i stick to the aluminum Prop or move on up to a Stainless steel?

There isn't a method to 'adjust' the hub. If its been spun, it needs to be replaced while you are repairing the damaged prop. If you are using the boat in a lake / river where the likelihood of impact is there, i would stick with aluminum and the 19" pitch. The damaged prop will likely have the dimensions stamped on the inside of the hub.
