Do you have some prop numbers I would like to know how the SRT3 11 pitch is doing for you. Top rpm's, etc. At 9.5 inch diameter you can go to the 11 pitch. How high have you been able to raise it up with your jack plate. How is your ventilation on turns. This is why I don't always go with the techs at PowerTech, our boats are much lighter than most and we can be more aggressive with our propellers. Thus my 10 x 10 was based on the weight of your FS18. I have talked to some of Techs at PowerTech and we always come up with the same props or alternatives when we take into account the weight factor, after a little bantering back and forth. There props are top notch.

Re: Mikem59 FS18 Build
Just a FYI~IMHO. Get extra cup and it will really help. I use a 4blade no cup which is about the same for me, but a 3 blade extra cup is sweet.

TomW1,
The SRT3 performed quite well. The hole shot is not as pronounced, but this FS18 hull gets on plane so quick I'm not worried at all. Already had to make a couple shallow water starts.
I'm definitely not hitting the rev limiter with the SRT3, but it seems to be in the proper operating range, I'm guessing I'm around 5900 to 6000 rpm. And, I did gain 3 mph. At WOT, I'm hitting 27 now. I'm pleased with the performance but have a couple of really good local folks that do prop work, may want to squeeze a little more out of her.
As for the Jack Plate, I've had her dang near all the way up with no cavitation issues. I'll need to take note of performance in the turns. And, get you more details on just how high the cavitation plate is when it's jacked all the way up.
As some of you here state as well as some others, adding some cup may be the ticket to really get the performance I'd like.
And, TomW1, thanks for the help, and the Powertech folks were very helpful but like you state, perhaps a bit conservative when the bumped me down to the SRT3.

Hope you all don't mind posting a couple of pics showing the rub rail installed. I meant to post awhile back and had issues. And, currently, laid up recovering from knee surgery, so have some time on my hands. I installed a Taco rub rail. Picking a hot day and laying the rub rail on the concrete driveway made the install quite easy. Easy enough my wife was able to help with the install. Rub rail sure makes a nice addition and protects the underlying marine ply.

That looks good!
Re: Mikem59 FS18 Build
Thanks Eric. I was pleased with how it looked once on. Certainly gave it more of the look of the production boats.
