Re: What year is my 105hp/ What impeller?
Hello adamhry and welcome to iboats. Your motor is from 1967. Parts lists dont go back that far but a sierra 18-3085 should work for that motor. 1974 to 1976 they used a different one which will not fit into your water pump and that was quick silver F438065 after 1976 chrysler went back to the sierra one. NAPA might even sell that part.
