Seaducer Rocking

[FloopyStat]

Guys...

I have a 47" gas seaducer that I have just finished building & test ran yesterday.

Speed was good, but with prop other than SD1, the boat rocks and rolls about. Speed is higher than with SD1 prop, so I would really like to use these other props if poss.

Also the boat always pulls to the right (need left rudder to track straight) with all props (including SD1).

Ideas???

I don't know much about the different props, but it sounds like it is chin-walking. Try reducing the lift on the prop (I don't even know how to do that ) as far as pulling to the right try twisting the strut slightly to the left. That will redirect the thrust to help straighten it out in the straights. (So I have read anyways)

I hope this helps a little

Try getting that prop real sharp, Your getting prop walk where it wants to push it to the right. I would lower the strut alittle and try that.

a sharp prop and if you want to take lift out of it, take about 3/32 from the root by the hub, to 0 at the tip.

are the rpms good in the turns?

Chine walking seems to be a problem with a lot of Seaducer's that I've seen run. I had this problem on an Areomarine Titan 21 and had to raise the srtut to get it to settle down. Taking care of one problem might help with the other.
