Pulling to the right

Hi everyone,

I have just recently purchased a 2013 PS197 and have found it pulls pretty hard to the right whilst over 30miles/hr. Is this a standard thing? As our family has young kids in the boat most times I would like to reduce or eliminate this from the steering as it can create an issue if your hands need to come off the wheel for any reason.

I have also noticed at around 43+ mile it has a cracking noise through the steering, it appears to be cavatasion, and can also be noticed if you use the engine to help push up on tralier.

Boat has now done 70 hrs in 2 months and problem has not got worse nor better.

As I'm in Australia, owners of these boats are few and far between.

Cheers Jason

Yes natural - take a look at the rudder - it has a slight edge on on the starboard side.

Pulling to the right is normal. There are alternatives for this characteristic but it's there for a reason, so I don't fix what isn't broken....

Cracking noise has me stumped. Not sure how to decipher that description. Cavitation typically occurs when the machine is in a hard turn (where water is washed away from the prop). Cavitation is not unheard of, but with an inboard, it's not always the first thing I'd suspect.

Hi ozzy_master,
Where in Aust are you? There are quite a few MC owners out here, once you've been for a while they'll start popping up.

As others have stated the pulling to the right is normal. This "load" on the rudder is there on a tournament ski boat for feeling the skier.
See http://mastercraft.com/teamtalk/show...0&postcount=12

As a tournament driver, I often add to the load of the rudder, by additional grinding.

As far as the cracking noise @ 43 miles, I've got no idea, but would think that at full noise/flat out, you'd be hearing a lot of noises, it would be hard to identify where that is coming from. Maybe spending a bit of time with the prop spinning while on the trailer and see if you can isolate it.

Let me know if I can help you in anyway.

Hey guys, cheers for the feedback.
I see the Ski Nautique 200 have an adjustable rudder to dial this issue in or out.

I am all ok with a slight pull to the right but due to the fact we have a fair crew of young kids an aggressive pull could catch an unexpecting driver out and launch a child overboard if not ready as it will go straight full lock, combine that with cruise and it could be a little risky.

I see the rudder design has taken into consideration the prop torque on the trailing edge, I was just wondering if anyone had machined with succcess to reduce this issue.

The rudder also shows signs of cavatation burn on the port side.

All in all, great boat though!

The Cracking noise is the first time I have ever heard anything like it in all the ski boats I've ever owned.

Not only do you hear it you can feel it through the wheel. It is very predominant and off putting.
Will be interesting to see how MC on the Gold coast appraise the problem.

A friend is an engineer at Lex Badleys marine engineering services and after explaining it to him feels it could be prop shape considering the signs of cav burn on the rudder.

Has the prop been reworked or changed? Can you verify the prop on the boat is indeed what is stock and recommended for the boat? Changing prop design or specifications can have some negative effects on performance. I know from personal experience the dramatic change in handling going from a 3 blade to a 4 blade made on my 200 MariStar. In my case I was fotunate the change was very positive.

Check your rudder for signs of cavitation burn which looks like an eroded area. I had a ding in my prop you could barely make out, but it caused cavitation burn on my rudder and made the steering pull extremely hard. I got a new prop and had the rudder repaired and my boat now has a slight pull.
