Mercury Tempest, Turning Point Mach 3 or Michigan Wheel Apollo?

the Sharrow miracle prop.

Sharrow Paperweight is likely more accurate

On the Sharrow, the best performance review I saw, which is likely lies, showed the Sharrow to be a few percent better than std SS props. At $2500+ and custom made, the Sharrow needs to be a lot better than the Eneria and the others for it to make sense to me.

If you go back and read the reviews and comparisons carefully, they weren't exactly on the Up and Up. They certainly didn't make sure the Props being used for comparison to were setup for best Performance. When I read them, I thought I was reading a Paid Promotion, kind of like an Infomercial

Not saying the raker is not a good prop. (If what I said got misinterpreted, just that there have been updates made to others in the last... 40 years now?) The enertia is excellent, just didn't run well on my hull. I even stepped up to a 21p to try and pull it down a bit to behave like others I ran... just wouldn't hold a plane below ~25 mph where others would run down to 19-20. Every once and a while you get a hull that bucks the trend. I've been trying to get my hands on enertia eco for testing as I think that'll match better with my hull.

That said I've tested my enertia (I have since sold it as there is no reason to have 5 different props sitting in the garage) on a few other hulls and that prop was straight magic on those boats. And by that I mean it corrected every single flaw in how it planed, handled and rode.

And the sparrow in concept is cool... but it kind of is just the same thing as a dual prop setup. The performance data they provide indicates that... albeit it was tested against an unoptimized setup. For the price you can buy a crap ton of fuel before it ever becomes worth it....

if you have a 16ft speed boat with a 135HP merc you are going to need a 24-25 pitch prop. i had a crestliner apollo 660 with th same engine and i was running a 23 turning point. It ran 51mph at 5900rpm. With a better hull thats lighter you need more pitch. just my 2 cents.

and i am a big fan of turning point. that,s all i buy now.

I currently am running a 21 or a 23 P 3 blade TP Hustler. The 23P prop is a bit faster, but not a lot, and it is a little slower out of the hole. Top speed is in the low 60's, or high 50's, with stock prop and set up.

The TP props are OK, but it may be that the Apollo and Tempest are a bit better. It is a guess.
