johnson 140 installed quick prop question

[deshet]

sorry for repost

Randleman is your prop a Johnson or Suzuki prop. The doing the install wants $200 for a used SS 21 but it has several nicks. I would like to start with some new or at least not damaged.

I have a new ss quicksilver typhoon prop part # QS6004x
The diameter is 14 and the pitch is 19 it is a 4 blade prop.
Do you think that it will work

Also if this prop will not work what size should be good on the V21 since it is a bit heavy. And I am a bit heavy then most 275lbs. and all of my friends are over 200 pounds

Thanks
