Prop help? 1990 21' small block??
looking for my buddy.
he has a 21' 90 with a small block and alpha drive.
he had a 17p 3 blade on it, have no clue what kind but its stainless. got it free.
put it on the boat and it seemed to plane good and go good but only ran4,000 rpm.
i was thinking the tach may be off so we will test that but just wondering what people are running on these boats to give him a good base.
he hits rocks a lot so alum prop would be better.
his old out board had atleast 3 props in 1 year. he boats in a place called rock pond. lol
