boat steers hard to the right

I have a 5m boat with a 90 mercuary outboard with a stainless steel prop

When the boat is moving you can feel the steering wheel pulling to the right. If you let go of the wheel it will turn violently to the right.

I want to get this fixed before i sell it.

Any ideas what is causing the problem

 have a look at the small keel like thing above the prop, it is adjustable and if it is set wrong or broken it will interfeer with steering. had a prob like that a while back but fixed it

Couple of things to look at...

Mon, 2011-01-10 20:45

Pulling to one side is normal on any single propped outboard motor especially when fully trimmed in but the trim tab can be adjusted to reduce the majority of heavy steering to one side .... normally they pull to the right.


Its also best to trim your motor to the desired trim position on the plane then note which way the motor is pulling.

If your motor is pulling to the right or (hard to turn left) adjust the trim tab to the right from its current position ... in other words ... if it pulls right adjust to right, if it pulls left adjust to left.

First mark its current position then adjust the trim tab till corrected.

 

I found out the hard way about the trimmindown/in on an old boat as some scumbag nicked the pin and instead of being set where it should be it was trimmed all the way down (in?).

not sure

I know in my tinny it steers hard to the right soon as you let go of the tiller, its so that if you are thrown from the boat the boat will just circle until it runs out of fuel, rather than run off and into someone or something else.  Not sure if its the same reason on larger boats or its a problem you have?

Great Adam - fall in and have your boat run over you

Time and time again just to make absolutely sure your head is caved in :-)

A really good reason to have the cut out lanyard attached to you just in case

You just cured me of a sore left arm caused by 5 years of fighting the left hand drag.

Another way around it.

Tue, 2011-01-11 14:07

Another way to overcome the problem is to fit another helm.

Teleflex "No feed back Helm" Pt. No. SH 4910. The helm contains a clutch mechanism which releases when you turn the wheel and re-engages when you stop.

I have one fitted and its great. I travel most of the time no hands on the wheel, and only turn the wheel to make minor adjustments in course. Uses the same cable, but I would recommend a larger dia wheel 15" as its a bit hard to overcome the clutch with a 13" wheel.

It is available, but you have to ask for it to be supplied. I brought mine at Dingy World.

Dont buy any other make, got caught out using a Korean brand, but the Teleflex works well.

Info is on the web, or I have more.

Worked out what the trim tab is. But still connfussed as to which way to turn it.

You said to adjust it to the right. However when you turn a rudder to the right the baot turns rigght.

Wouldnt i want to adjust it to the left???

Adjusting trim tab

Tue, 2011-01-11 21:21

 The outboard motor acts as a rudder turning your boat. using both the thrust of the prop and the shape/surface of the leg. The trim tab turns the leg of the outboard. The leg/prop then turns the boat. Thats why the tab is adjusted in the opposite direction.
