Suzuki DF70 noise in gear
I have a 2001 Suzuki DF70 (came with a cracked lower unit case) with a 2004 DF70 lower unit, I bought this lower unit used, and unfortunately it had a bent prop shaft (1/16” runout), which wasn’t disclosed. So I put a new shaft and seals in, put it together and in gear it makes a bit of metallic rattle. I cannot recall it making this noise before but I haven’t run the motor much on muffs.
I have checked for play axially and found it to be within spec (no fancy tools but it barely moves), radially it feels like it moves ever so slightly side to side but there is no runout of the shaft that I can see when running without the prop. It only makes this sound in gear, it is louder in reverse and only happens with a prop on. Prop off and it is smooth as can be.
