Advise on getting her right. (Plytanic)

I took the first real runa nd it went well, but I had to run the motor tucked all the way in or it would ventilate, I have a spare 4 blade on her and I'm thinking about going back to a stock aluminum 3 blade (my original was bent in a wreck). Can an aluminum prop be cupped a bit? if so how much does that usually cost? Think this would help the issue?

Other than that I think I need some tabs, I need her to plane quicker and stay on plane at lower speeds. I was also hoping this would let the TnT to be used to adjust running angle instead of having to be tucked all the way in. I have some things worked out in my head, I was just wondering what you all think? here's some picks.

 

I can't afford Lenco's now. About the only thing I can really afford is either a hydrofoil, or smart tabs. I;m leaning towards the smart tabs, this way I don't have to drill my new lower unit.

Any thoughts on the Prop? any major advantage one way or the other between a se 200 and smart tabs?

 

That's exactly what I was thinking. I busted out my old 3 blade and a ruler to see how far out of wack it was. It's actually not bent as far as I can tell from takeing measurements off of multiple point along the 3 blades. However it does have a good size chip in it, I think I will throw it on just for a test run to see how she does. If it runs better with a 3 blade then I will buy a new one and have it cupped (or buy the yamaha prop that is already cupped).
Do I need to go up in pitch when cupping, or is it still close enough?

 

The sport clip won't fit my motor, I've tried, it's only for 25hp and up. I really don't want to have to drill the motor again if I can avoid it, but will keep it as an option.

As far as getting the prop fixed, I have a friend that just had one fixed, he is not that happy with the results cause when they smoothed the prop it changed the diameter a little and ended up raising his rpm's and lowering his top speed. I'll have to call a shop and talk to them about it, a new prop is only like $60 so I think I might go this route to just start from a clean slate. First I'll have to see how the 3 blade runs.

 

anyone know a local shop in the tamps/lakeland area?

 

Thanks guys, ?I have a solas right now, it's not bad but if I can buy a genuine yamaha prop that will work I'll go that route as I found they have ones that are cupped from the factory.

Now the question is what to do about pitch? When you cup a prop I know it does something to your RPM's right? I think it cuts them back a 100 or so if I remember? Last time I checked my motor was running about 5450-5500rpm's, my range is 5000-6000rpm's on this motor so I was right in the middle, if I can increase them a little it would be nice.

So should I go down to a 9 pitch prop when cupping, or stick with a 10 pitch like it came from the factory?

 

OK I checked on the solas props, I can't get one for my motor that comes with cupping so that is out. I can get the yamaha prop, but not until tuesday.
If I want it by then I have to order it by 3 today. So hopefully someone will respond and let me know if I should go with a 9 or 10 pitch?

 

I didn't order it yet, but I guess I could go with a 10" pitch, Thats what I have now, but doesn't cupping make you lose a few hundred rpm's?
I looked into the turning point props and they have one that will fit, but it's $2 more then I can get a yamaha cupped prop for. What would you guys do? I'm still thinking about sticking with the yamaha.
