suzuki 2.2

[ivanhoe]

hi,<br /> i've just purchased a used 1997 suzuki dt2.2 outboard privately. it ran good on my lake but when i went on a fishing trip, it acted up! the symptom's are:<br />1- at idle, the engine seems to be knocking(kicking) and the steering is not staying put(yes, i did tightened the shaft). <br />2- when revving up to a higher speed, you could hear the sound pitch change(fluctuating) on it's own.<br /><br />the thing i've noticed was the shear pin on the prop was broken and i replaced it before the fishing trip but the prop is somewhat loose even with a new shear pin. the old pin did some wearing on the prop. the question is, could a loose prop be doing my above symptom's?

Re: suzuki 2.2

I'm still not totally clear on your problem, but a loose prop can cause lotsa problems.<br /><br />If the prop bushing is worn it won't hold the shear pin securely, nor will it allow the prop to snug up. That could cause "wobble" and even a slight bit of tilt/wobble could (I suppose) cause what you are seeing. <br /><br />The pressure around the prop disk is not equal and is constantly changing. If those fluctuating side loads (for want of a better term) hit a loose prop, the prop will wobble on the shaft.<br /><br />I'd suggest you pull the prop and check the fit of the bushing and the shear pin into the bushing. Bushings are around $30.00 at the dealer, but last a loooong time.<br /><br />What confuses me is why it would run fine one time and then exhibit this problem. Not typical.<br /><br />Lotsa words, but I hope they help.
