PROPULSE-adjustable,configurable props from Sweden

[MatFromPoland]

Friend of mine is pushing me to buy one.

For example for my boat it be 9901:



Based on some adverts: ProPulse 9901 Adjustable Pitch Propeller 90-300Hp | Trade Me

1. Each new set contains 4 blades which you can individually configure
2. You can adjust pitch (for example for above mentioned prop it can be 14 - 22")
3. In set you have one spare blade.
4. You can adjust angle of blade also to have better speed or better grip
5. Material is lighter than ALU (usually use for ALU props) but stronger
6. When you bump in the rock it is less probability to damage engine - usually you damage some blades and you can keep a few as spare.

So much about producer info. Anyone has any experience with them ?

I have checked prices and looks like best one is on producer home page 195 EUR for 9901 prop (shipping 29 to Poland)

You're aware that they're composite?
Plenty on the internet, much of it by people who are trying to sell them to you....
Testing the ProPulse Propeller

Is the friend who is pushing you to buy one using one themselves or are they just trying to get you to buy one so they can see what they're like before shelling out themselves?

You're still going to have to ensure that the engine is within the engine manufacturers specified WOT range, so once you've established best pitch you'll not be altering it - assuming these will adjust to within the range.

One of the users of Polish motorboat forum bought one and is happy (inboard engine).
Based on producer website it is polyamide

The parts are molded in a fiberglass-reinforced polyamide, which is an accepted substitute for cast metal, mainly aluminum.

Maybe I'm wrong but I was thinking also that I can tune prop to condition and load.
When use on lakes I can make bigger pitch. More load or Sea condition - make it smaller.

The Propulse seems to be a little more expensive than ALU but many times cheaper than VIPER or REBEL (stainless EVINRUDE props). So maybe I will buy it test and share my experience).

After watch this movie and description I'm going to give up on this prop I think:

Description states that he loosed blades. Maybe it was his fault when assembly prop but I'm less curious now ...

So this is what some EU Propulse dealer advised me:

Yes, if ventilation often occurs, I would not recommend that due to the fact that blades may break.
There are special thick blade props used like cleaver and some Mercury Propeller types I know.
So if you say that your rib is often "flying" over waves, the propulse will not be your type of prop.
But of course you can ask them at propulse.se what they recommend you.
It is a lot of money wasted, if the prop blades are always defect.
