Prop......

[dwhatty]

......reconditioned, repitched & reinstalled

 

[Peter B]

Is that PropSpeed on there, dwhatty? If so what is your experience with it in terms of lasting etc? I normally get a really good ablating anti-foul like International (Interlux) Micron 66, but the harder anti-foul they apply to the running gear is always the first to go, thereby detracting from the extra gained from the better anti-foul. They talked me out of PropSpeed, but next haul-out, which is soon, I'm considering.........

 

[dwhatty]

No prop speed or anything on there. Never have used anything on our props. Thinking of trying some Super Slick (http://store.hamiltonmarine.com/browse.cfm/wax-super-slick-16-oz-bottom-paint-alternative-138972/4,8796.html)* as it has worked okay on our dinghy prop the last couple of years.

Here are some before and after pix of Propspeed on my wheel. The "after" picture was a little more than a year later.

RE: Prop......How many engine hours between haulouts?

Keith,

Those photographs are impressive! How many engine hours were used during this period of time? Average amount of time passing between times the vessel was used perhaps as well.

Thanks,

John

I can't speak highly enough of the product (Prop Speed) have been using it now for over 5 years, normally get at least 18 months out of a well applied coating on a properly prepared prop. (no I have no interests in the Company)
Previously used different types of hard anti foul and even heated the prop and applied a coating of lanolin (Kiwi love juice) non of the above really worked.

When I have a better connection I will post some photos from previous slippings.
I lay alongside my berth for a few months each year after a slipping before i take off cruising, prop is allways as clean as a whistle when I leave.

If you do any shallow water work you can easily blow of your protection with the stirred up sand (this will happen with almost any coating)

Benn,

Thanks for your response. I have heard nothing but good things about Prop-Speed recently, but never have had the chance to use it or seeing it being used. How does it hold up with lots of underway time?*Does it wash off at all?*I guess I am asking is there a lifespan figure available based on engine hours as it does not appear to degrade when in a static no use state from what I have learned thus far.

It is quite obvious it appears to do the job for vessels*which operate on an infrequent basis. Nothing better than hearing from folks who are using it with good results.

Looking forward to your photographs as well.*

Will have to take a look at their website and learn more.

My experience with PropSpeed has not been good. Very expensive to have done. ($400)
After two years, with my diver being very careful not to remove it, here is what it looks like.

Exactly two years since application

I've seen a lot of posts on T&T that reflect what SeaHorse has said. PropSpeed is expensive and the end results are not worth the money, is the tone of most of the posts. Some people have said they've been happy with it, but this may be due to their being in a different water environment than other posters, or after spending $400-plus bucks to have a coating painted or sprayed on a prop, they may be reluctant to admit they spent their money for nothing

Marin,

Thanks for your input. I had heard similar things several years ago and that plus the expense of it caused me to look past.... but now have seen the comments here.... kind of got me curious again.

I wonder what the issues are? Prep of prop? Water temp... corrosion issues? If anyone has any more input I am all ears on the this one.

Yeah it's all in the preparation.
Depends on what you expect.
if i use hard anti foul or other products my prop is over grown within 2 months.
This prop stays very clean for long periods of time.
As I have stated previously stated when working the boat , normal use no problem, sand blasting will remove the coating in various stages, but this is true of any coating.

Like all vessels if you use it every day don't even bother to coat the prop.
On all our ships and rig tenders the props are never coated as they are in continual use.

Don't expect the impossible.

But if you use your boat occasionally this fills the bill and you don't have to dive and clean your prop every time you want to leave port and that to me is worth the $400.00 every 2 years.
I haul my boat at least every 12 months as she is a timber vessel.

thats my 2 c worth.
I think there are pictures of my prop on my page on the Passage Maker forum, if you can spare the time to delve into that slow site.

[Keith]

My pictures represent only occasional use in that year. Mostly sitting at the dock, probably around 75 hours underway. The coating was a little tattier than I would have expected, but is working perfectly.

 

[Baker]

I have heard surfboard wax does a good job as well??? Goes on easy and stays on and prohibits the ability of growth to get a grip.....cheap too. I will be quickhauling soon and gonna give it a go.

 

[Bendit]

It's in the preparaion and the application. I applied it myself, the first time about 6 years ago and it wasn't great. Now I use the yard where I haul and they sandblast the prop first and have the timing of the two coats down to a fine art. Too quickly or too slowly will give unsatisfactory results.

We get two years comfortably between applications. The bow thruster props last 4 years. Prop Speed has to be the biggest advance in underwater coatings I have seen in nearly 40 years of boating.

If you're not using it, you're wasting fuel!

 

[Carey]

I have used silicon spray (not to be confused with silicone) on my prop with good results as well. Same stuff you would spray on antenna connections to prevent corrosion.

 

[Tidahapah]

Here's a few photos of my prop and prop speed applications over the last few years.
I was going to send them to John but didn't have his e-mail address so have included a couple of photos of when I blasted her back to bare timber in 2005.

I had propspeed installed in November '09. Expensive to do right, I'll know after the next haul out if I want to continue or have diver scrub of barnacles every 6 months. He is down there anyway to change zincs.

 

[Nomad Willy]

I used Armor-all. Prop stays clean for over a year.

Most of what has been said above concurs with what I have found talking to owners who use Propspeed. It works by being 'slippery', but is quite soft, so the thing is to be careful about not running aground or into shallow water such that the prop is stirring up a lot of abrasive bottom.. If you can avoid that, then it appears good for the boat not used constantly, so Benn & Jeff B's & others similar comments are spot on I think. I'm going to try it next haul-out. Mind you, I was in real clear water the other day, (off Myora Benn), and had a good look at my (the boat's) bottom, and the Micron 66 is holding up well, and the prop and rudder weren't far behind, with just the usual hard anti-foul, and that was 2 yrs last Easter...
Any more news out there - trustworthy, that is - re this ultrasonic anti-fouling system. Now there's another, which is two electrodes, one each end of the hull, I gather.....?

 

[sunchaser]

Peter

You're close on the electrodes except one goes in // through your wallet

 

[Capn Chuck]

Peter, These ultrasonic units have been around for a long time and the facts are, they do not work. There is no science except the faulty kind generated by the sellers, that it does anything except lighten your wallet. This is pretty much snake oil technology, but if you should decide you have to have it, send me 1/2 what you plan to pay for a unit and I will send you a battery operated unit that you can hold in one hand and run off AAA batteries that I guarantee will do as good a job as the more expensive units out there. Chuck

 

[Tidahapah]

Peter B,
Agree with all that has been said here re the ultrasonic units.
There have been a few dud reports on them in our own Cruising Helmsman of recent months.

Benn

 

[Peter B]

Yeah, when something sounds too good to be true, (like those Nigerian money sob stories), it usually is exactly that - too good to be true.

 

[FF]

"it usually is exactly that - too good to be true."



GASP!

You mean I didn't win a huge lottery I never entered?

 

[Keith]

Actually you did, FF, but you need to send me $500 for the claimant fee.
