Boat will turn to the right by itself, propeller issue?

[BoatAddicti0n]

Can anyone please advice is this might be related to the propeller?

The symptom is that the boat, by itself, turns to the right (while the steering is straight).
I obviously have inspected the zinc anode fin and engine: everything seems to be aligned.
Also have checked the Teleflex/steering system which seems fine.

The boat is a Swedish Ryds 495 GT (16"), aprox. 320 kg unloaded, powered with Johnson outboard 60HP 1988 3cyl, original aluminum propeller (probably 12 1/4x15), which shows the signs of years of use, but does not seem destroyed.

Yes, actually it is a prop issue. Single Props turn only one way, makes stuff want to go the other way, or the same way depending on what stuff we're talking about . . .

You don't inspect them, you adjust them . . . Here is an FAQ that will help. Without power steering be aware that fixing one pull might lead to a different pull at a different speed/RPM. Changing props can change this dynamic as well. The best you can get is a decent compromise based on the way you run your boat.

did you adjust the anode fin ? you can adjust that to counter the direction and make it less pronounced..might help a bit...

Are you refering that when you center the steering wheel straight, like in your car/truck, the boat is trying to turn to the right. Or are you refering what happens when you let go of the steering wheel?
