...propeller direction of rotation? Inward or outward can make a big difference...sometimes spinning inward will cause this type of handling.

Thanks HP. Currently, the props are turning out. I havn't really thought about trying to see how it does with turning them inward, only due to the fact that Cig does not recommend running the props turning in on this model/step configuration. Although, its somthing I may need to consider when I get the boat back in the water.

Beautiful, Thanks for the pics!!!

Very interesting dilemma;

Did cb@dragon have in "inside info"?

Maybe a inexpensive trial would be to add Latham drive spacers. I know your drives look low enough but it sure sounds like they come up out of the water when you list side to side

or the props are just "wrong" wanting to "climb" to the surface too much. This could give this effect. Wanting to surface, falling back in, side to side.

Yes, I've thought about that also. I think its prop related too. But like I said earlier the props push the boat to the correct rpm and speed at WOT. I've read where the new 5 blade may help this issue and thats where Throttle Up will come into the picture this spring.

The boat does not rock back and forth (side to side), its like you are running straight in smooth undisturbed water and when you pass thru some waves at an angle or even get hit with a cross wind, the boat will lean a bit. Thats when an engine will gain rpm.

The know drive spacer may help this as well if turbulence in water flow is helping cause this, however, I do not want to loose any top end performance. I'll just have to experiment some with this.

Thanks for the input.

It sounds like the props have some slip going on and when the boat is allowed to drop one side, the prop going deeper will obviously get a better bite and the one being raised will get even more slip. What speed/rpm range does it seem to happen at? Does the hull seem to lean from side to side easily at the speeds it occurs at? Does a little tab help stabilize things? I would think spinning the props in will make matters worse. How does the hull feel in the higher speed ranges? I am certainly no Cig expert, just fishing.

I dont realy think you need to keep them perfectly sync'ed .. all the time
close is ok ..

Yea... I know what your saying. I'm kinda of one of those guys that likes things to be right all the time. I had a '93 Fountain 35 Lightning for ten years. Which was a good boat for me. Put almost 800 hours on her. The props were always hooked up, and it was easy to handle, probably due to a conservitive set up. I know I get my Cig right with just a little work. She's a great boat.

All our boats sound good running when the engines are pretty close in sync, and there is nothing better than that. Thats all I trying to accomplish. Its all in set up and I understand that.

Checked the drive angles? How much toe in/out are you running?

Maybe one the hydro "plus" props would help?

Maybe a new fountain would fix the problem? Your old one still runs 82+ (GPS now) and handles great. I sent my new hydros to Throttle-Up for labbing. Always looking for a little more speed.
