I am in no way connected to this company, but wanted to give my report on getting my prop “worked” by Andrew. I purchased a T1 Yamaha SHO 24″ non vented prop about 8 months ago. I was relatively happy with the prop compared to the 24 Tempest Plus that came on the boat (its now my spare). I have a 2017 Sabre FTD AE with Dual consoles, a Fortrex on front, and a 2017 Yamaha 175 SHO engine. The engine has about 30 hours on it. So, after reading and watching a few videos Andrew does on YouTube, I decided to send the SHO prop to him. He measures the specs with some sort of MRI machine. This was a stock prop right out of the box, and brand new. The pitch was supposed to be 24″ . Blade Averages turned out to be 23.430, 24.043, and 23.437. Cupping was “deformed”. Andrew worked the prop…Blue Printed and Dynamically balanced, a pitch change and lab finish/polish. The end result is a prop whose blade averages are now 24.557, 24.570, and 24.547. He also fixed the deformed cupping. Prior to this, the boat would run about 67.5, plus or minus, and the chine was fairly great above 62 mph. RPM was 6030. The after results are: 69.8 mph GPS, better bow lift at lower RPM, chine walking is much reduced and easier to control. RPM is 5980, give or take. He also suggested I raise the engine from 3.5″ to 2.5″ PTP. Water pressure is fine at this setting, depending on trim. Hole shot with me and a full belly tank of fuel is 3 seconds…with live wells full, its 5 seconds. A slight amount of blow out when the bow comes over, but I can basically begin trimming immediately. I can now cruise comfortably at 60 mph turning about 5K RPM, give or take. I can take my hands off the wheel at those speeds, but of course have to drive it above 60mph.Bottom line: Im happy with the results and think Lake Lanier Propeller did a fine job. The turn around time was 7 days. I spoke with him on the phone a couple of times during the process, and he is very customer service oriented and asks a lot of questions about what youre looking for before proceeding with the work. You do fill out a couple of forms to let him know whats happening, but he follows that up with at least one phone call.I know there are other great prop guys out there, but I am personally happy with the results.

Could you please explain this sentence for me? ” He also suggested I raise the engine from 3.5″ to 2.5″ PTP.” Im acronym impaired.
Prop shaft to pad

We only ask if you have an excessive tail above the engine cowling, or have an excessive amount of torque on the steering wheel on top end. If there is torque or excess tail, then the engine is too high. If not then your good. If it is tool high then you might have more performance left. Try it down in 1/4″ increments.
No excessive torque on the wheel. I honestly did not look at the rooster tail ( I was running the Alabama River and you have to watch for floating debris), but at WOT the water pressure was still in the 15 – 20 psi range. When I get to go over to Lake Martin I can tweak things if necessary. I am 98% sure the tail was not over the cowling from the way the engine and boat were running. The SHO prop is a big wheel at 15 + inches in diameter. I will follow your advice though, and drop it 1/4″ to see what it does prior to my next trip out. Only takes a couple of minutes to change the height when you know where you are to begin with.
