I just got my (new to me) Renegade Bass Prop in the mail today. I received this Prop from another BBC Member and it is in excellent shape. My question, The plastic vent. ring that he sent with the prop appears to be melted a little on the prongs that go in the lower unit. Should I run this one or call Mark and see if he can get me an aluminum one for the engine. Engine is a 03 Evinrude 200 DI. Prop , as mentioned, is a 25" Renegade Bass prop...Will my engine melt another one of the plastic ones if I get one of those?....Thanks in advance!!
