Boat pulls to right!

I have a 2001 Capecraft 17cc w/2001 Johnson 90 w/ 14 x 17 prop.<br />This boat has had a steering problem since I bought it. It wanders all over when going slow which will not allow you to relax because of constantly correcting heading. At any own plane speed it will start a right hand turn if I release the wheel. It gets very tiring to constantly apply steering pressure to compensate.<br />I have adjusted the trim tab to its limits (the correct way) but it still turns. It also will not backup worth a crap, but being a modified V probably causes that.<br />Is it possible that the motor is mounted too high? It could go down about one inch before hitting the transom.<br /><br />Please help I would like be able to rest my arms !

Re: Boat pulls to right!

There was a post last week about this being a ventilation problem. Boat gets up on plane and the prop vents (pulls air) and it pulls hard to the right. Post didn't say anything about wandering at slow speeds.

Re: Boat pulls to right!

The cavitation plate should be close to being even with the bottom of the boat. Then adjust the trim tab in the direction of the pull.

Re: Boat pulls to right!

Could it not just be boat balance? Check weight onboard is evenly distributed...including bilge water! Even your helm position being off to one side can make the boat turn

Re: Boat pulls to right!

Hi GR,<br /><br />That's a centre console with underfloor foam, right? So if you're solo, weight balance should not be a problem, provided everything portable is stowed correctly.<br /><br />Basic questions - have you checked the hull for damage or assymetry? This can play havoc with steering pull. Or have you verified that water has not got into one of the foam cavities? And - stupid asking, really, but I have seen it before - is the outboard not only centred on the transom port to starboard, but at a true 90 degrees to the hull, viewed looking towards the boat from the rear?<br /><br />Apologies if I'm teaching grandma to suck eggs with these next comments, but I dunno how long you've been boating, of course. - At low speeds, especially when angling across a low, short swell, boats appear to wander when in fact their course is more true than the eye realises. An inexperienced skipper will keep correcting when there's no need. And going astern with an outboard is never as accurate as going forward.<br /><br />Ciao

Re: Boat pulls to right!

GR I have same boat except a 19'CC I do not have this problem, my steering is straight & I do not have the pull to the right. My cavitation plate is 1" above the bottom of the boat ,this is more important than concentrating on where the engine is sitting on the top of the transom .I have a 2"<br />space from where the motor actually sits on the transom. It is bolted on the third hole from the top. The boat runs great the only complaint I have is how itchy everybody gets & it must be the rough finished interior with the speckles.You can't come into contact with it or you will be scratching for a while.<br /><br />My cousin had a 19' that did the same exact thing you are talking about & it is no fun it really tires your arms out. I really hope you can get it fixed so that you can enjoy your boat.

Re: Boat pulls to right!

Do these boats with a steering problem have power steering?

Re: Boat pulls to right!

The reason I asked is because my brother had the same problem on a wellcraft. We disconnected the P/S on it. No more pulling. Turned out the pump was bad. Try disconnecting yours. Can't hurt, you can always put it back!<br /><br />Smitty

Re: Boat pulls to right!

V4's did not have power steering even as an option from the factory. Neither did 60 degree motors. Since this is a 60 degree V4 the only way it could have power steering is if it has the Hynautic Hy-Dyne system. If so, that would be rare.<br /><br />If you have wandering with an OMC outboard power steering unit the spool valve needs to be reshimmed. <br /><br />Some boats I've been in that wondered badly at low speed with tight steering had the motor mounted slightly off center. Actually if you resist the temptation to correct it, it will come back on its own most times. Still very aggravating. <br /><br />Pulling to the right once on plane is a normal function of a single engine with a single right hand rotation prop. Damaged or worn motor mounts, among other things, can accentuate the situation. Its very common to see the torque tab adjusted the wrong way. <br /><br />Trim angle has a lot to do with it also. As does motor height. In this case GR also mentions that it doesnt back up correctly. All this leads to the (silly) question of -- is it a 20" motor on a 25" transom? If not, being up 1 hole should not present a problem at all.<br /><br />Lets hope he returns and lets us know what he found.

Re: Boat pulls to right!

I know a guy who owns a Maxum that wanders AWFULL at low speed, but thats an I/O. I dont think there is anything wrong with it, its just the nature of some boats. Rather anoying though.

Re: Boat pulls to right!

Length for length, American sport boats tend to have a wider beam than their European counter-<br />parts. Beamy boats wander more readily than narrow-beam craft. You pays your money ...<br /><br />Back to the subject ...Dhadley has hit the nail right on the head as always.<br /><br />This is the sequence we usually follow:<br /><br />First off, eliminate the red herring of normal torque-steer - does the owner know that a boat with a single prop will naturally tend to describe a large circle? (That’s another reason for a kill-switch - it stops the boat arcing around and finishing you off!) Adjustment would include correct setting of the torque tab as has so rightly been said. Bear in mind here that the pitch and diameter of the prop will also affect the degree of torque-steer.<br /><br />Next, if fitted, verify the correct operation of the power steering system. Some systems can exert a huge one-sided pull if not working right.<br /><br />Still not running straight? Then go for the three fundamentals - balance, symmetry and wear - in that order. <br /><br />Checking balance is easy - see if the boat has any list when sitting in still water. Correcting it might be as simple as rearranging gear in the boat, or as problematical as locating and curing water egress in one or more of the foam compartments.<br /><br />Symmetry basically means striking an imaginary line along the boat bows to stern, including the <br />outboard, and confirming that everything shapes up identically, port to starboard. Is there underwa-<br />ter hull damage, or uneven hull growth, or motor misalignment on the transom (up or down, port or <br />starboard, not at right-angles to transom)? If fitted, are trim tabs adjusted right and operational? Has the skeg been hit and bent? <br /><br />Here, algae growth is a big problem. Algae love sunshine and warm water, and a boat habitually <br />moored in the same direction alongside a quay with one side in comparative shadow, can get more <br />growth on one side of the hull than the other by the end of the season.<br /><br />Wear is self-explanatory. Is the steering system or outboard old or heavily-used? Wear in the mounts of either will allow the torque-steer to become magnified and exert an annoying pull.<br /><br />It’s amazing what boat-owners do. Some use old tires as fenders here. Leave them hanging over the <br />side when the boat’s underway, and it will almost spin on its own axis - and the guy wonders why <br />his motor’s tugging!<br /><br />Ciao
