Propeller Choice?

To go with my plea for advice on engines can anyone help on this one? In middle of buying my first RIB. Need to make decisions on engine soon. Chap today suggested might be worth having a duo prop. Anyone out there have any experience of these on a RIB. I think they can be fitted to the Yamaha outboards. Is it worth the cost if I do go with this engine to have one fitted? Can they be fitted to either Suzuki or Evinrude E-tec? Read a couple of threads on this and sounds like might help on fuel economy and performance. Any advice gratefully received.

Hi Jeff,
Unfortunately I don't think duo-props can be fitted to any current outboards.

Yamaha used to do a duo-prop on one of the older V-Max motors but I think it's discontinued now.

AFAIK duo-props are now for inboards only - typically Mercruiser Bravo 3 and Volvo.

Generally the prop supplied with the engine is very suitable for it! Although the Suzi's come with Ali props which I am told tend to ventilate a little too easily.

If you really need to mess about with it then arrange with the people you bought the engine from to loan you with a size up and down from the standard and see which you prefer.

Alternatively speak to some experts, Julie from Steel Developments or there is an excellent company in Poole who's name escapes me!

Yeah, our Yamaha prop is excellent... our Solas prop is, err, disappointing!

The TRP Yamaha system you can fit it ONLY on a Yamaha engine. This is what I have been told. However, as the leg is shorter than a normal L Yamaha you need also the axle and you need the full unit. The TRP system is brilliant, is like putting a 4x4 on a boat and the Yamaha system was/is the most reliable. Now is discontinued but Yamaha still sells all the parts as well as the total system.

Here (UK and Europe) the prices are forbiding to buy such a system (just the props alone cost near to £1000 each).

HOWEVER, if you go foreign you can buy it in the US for less than half you pay anywhere else.

I highly recomend this chap EXTREAMLY RELIABLE

Ask him the question and will be able to help you out.

Also this chap Ray Neudecker [neudecray@hotmail.com] he is an engineer and he loves the TRP engines. He may also be able to point you to the right direction

Good luck

Yamaha stopped making that system for 2 reasons: expensive and no demand.
But it proved to be very efficient, especially on ribs. If Iím correct they only made a version with 150 HP. But some people were able to make it run very well on 200HP outboards. If you are interested in one you could send a mail to info@bruggemarinecenter.com. I know they still have one or more 200 HP versions.

It ACTUALLY runs with the 200 I have one! But as I said you need the full leg including the shaft/rod that connects to the engine.

There is also a Yamaha 200TRP MDDI which is a 200 HPDI TRP duo prop it retails in Europe for 40-46000 Euro, in the US a lot cheaper than that.

For the new motor with the TRP prop from Europe CHECK HERE I think is SEAHARRIERS company

The market price for a used leg with the prop with the SS props that is availiable must be between to £1,000-1,500 (used but in extreamly good condition £1500 is the TOP TOP price you can pay). However you must be able to check that the seals are good (no leaks!), the gears in the gear box work and that it does not lose any gear oil. If is more than that get it form the US

Is different of course if all of it is brand new and you have a manufacturers wrrantee with it.
