Heavy Steering on DR 490 with 60 Hp

[two stroke mick]

I am wondering is it normal for the steering to be heavy when the engine is trimmed in. The steering becomes much lighter once the engine has been trimmed out when I am on the plane. The steering is mechancial not hydraulic

During my PB2 I was told to start with the engine trimmed all the way in.

you thoughts please

Well, you start out with engine trimmed in to help keep the bow down as the boat tries to climb onto plane. It shouldn't affect steering effort.

As to why this would affect steering, I don't know. Does it happen while sitting still as well? If so, I'd suspect cables being scrunched up or pinched or something similar.

If it doesn't happen except while moving, then I have no idea.

The steering is light when not moving it only seems to be heavy trimmed in and under load. I just checked it and the steering is light when there is no load

Is there any play in the steering bushes on the engine?

Fairly normal I am afraid. I have a pair of DR 490s and a V 520 here and all have this steering issue. Although it is noticable on all outfits not just valiants to some extent. Correct trimming will help you out, If there is an indication that this problem is getting worse then the steering may need attention. Steering may be loose when not under load but stiffen when forces act on it.

I would have a look through timming your outboard and see how you get on.

Hi minimerc

The engine and steering are new so I dont think there is an issue with the equipment. I am wondering am I correct to start off with the enging trimmed in?

Quite normal for many setups - experiment! Try and find a happy medium between steering load and the bow pointing up to the sky when getting on the plane. The problem is every boat is different with props, engine height, weight distribution engine HP etc, so there are no hard and fast rules.

The general rule as your instructor told you is to trim in to get the boat on the plane as easy as possible, but vary the trim angles in small increments until you get a result - hope that helps?

Heavy steering indicates too much drag... When you're engine is trimmed in all the way it sticks deeper into the water, you can try to raise the engine one hole on the stern, that may dramatically help...

Yes trim down to get on plane (Down for power up for speed)

As suggested you could lift the engine a bit, may help, I have my engine on the v 520 up two holes. Goes faster, less steering issues but prop a bit close to the surface so ventalates a bit at times. It suits me that way.

I would suggest you suck it and see, dont be to keen to alter your rig untill you get a few miles with it. I would think with a 60 on a 490 you wont have any problems getting on the plane so just dont trim all the way down. The trim up as soon as your boat goes flat. In small steps.

Have you got the 490 with the small steering wheel? One of mine has and this makes the problem seem worse than it is.

I could go on about trim all day but the best thing to do is experement and dont be to quick to change the trim. select an angle and see what your boat does throughout the manovers. Then alter a small amount and try again.

Dont worry about it. Just enjoy.

I adjusted the trim tab (on the cav plate behine the prop) the steering is no relativy light when fully trimmed in. In a choppy seas the engine fully trimmed in makes the rib much more comfortable to use. As a result I now can travell at higher speeds with comfort in choppy seas.
