Merry Fisher 805 steering pulling to the left

[icecool]

I have just sea trialed a 2005 805 and over 10 knots or so it was pulling on the steering very strongly to the left, this didn't change no matter what direction I was pointing and the broker said it's because a single shaft drive will tend to do this, any one had this experience?

Some boats tend to pull one way or the other, how is she loaded, i.e any list when stationary unmanned. Has she got trim tabs fitted?

I have a Jeanneau 6.5m single shaft and don't have any such problems at all.........! Agree with Omega2's tabs question!

 

[RobWales]

Also if it has a teleflex type cable steering and helm you may want to check the grub screw on the helm unit which you can tighten to increase the turning resistance, if very loose at present I would suspect the symptoms you describe...

It shouldn't do this!

Had the same on our little fairline, was so bad could not be corrected by steering the opposite way, was as suggested above, trim tabs needed programming!

It probably hasn't got trim tabs, over to the OP.

 

[No Regrets]

I have never seen a single shaft drive pull to one side. I have had a few!

You might get a tiny bit of prop walk, mainly in reverse, but this is a mystery!

Rudder stock bent?

My MF805 does the same AND has marked prop walk.

My ran true, is it listing ?

 

[thejonesey]

Mine ran true too but with a port list because fuel tank and (usually) most passengers on that side.
