Testimonials

I've finally put my propeller back on my boat about a month ago. You guys re-pitched the propeller for me quite a few months back.

Just to let you know it is spot on now the engine now does 3550rpm full throttle which is spot on. The boat now has a max speed of 7.5knts and cruising at 6.5 a huge improvement albeit half a knt is huge for my little boat LOL.

The boat is only 20feet long displacement and 7 foot wide harf chine and launched in 1947 and has had an extensive rebuild.

I re powered it in 2005 with a brand new Nanni 30hp diesel which replaced the Nanni 16hp. Made a huge difference + your propeller work for me

     Thanks guys you do an awesome job!

Graham Cox is a long-time member of the OBC in Orakei and a long-time customer of Ovlov Marine. Ovlov Marine sold him his original 200hp duo prop for his Vindex 350 and then re powered it adecade later with a KAD42. He then brought a Sea Ray 39 and uses it regularly to commute to the bottom of Waiheke and for cruising.

The Sea Ray was powered by 2 x 2.7L 350hp big block V8s (not Volvo Penta engines). Ovlov Marinediscussed re powering with diesels for the last 5 years and in the end Graham found the V8s tobe too unreliable. After the last breakdown in November Graham looked at the reliability and
exorbitant fuel costs and took the bold decision to re power. all options were looked at, particularly his required cruising speed of 20-22 knots.

The V8s had a top speed of 24 knots and you probably could not guess how much fuel was burnt! the D4-300 HS63 2.04:1 engines and gearboxes were selected on the basis that they would fit comfortably in the hole, and on calculations by Mark Power at Henleys Propellers that they could
reach 25 knots and cruise at 18-19 knots. Final sea trials showed a top speed of 25.4 knots with an average up and down wind of 24.5 knots with max revs of spot on 3500. Cruising at 3000 revs gives 21 knots @1.89 L/NM per engine.

Graham is very pleased with these figures and is particularly impressed with the quietness of the engines. He had always believed that diesels were noisier than petrol engines, but has beenpleasantly surprised. He is also impressed with the torque of the engines, ( this torque gives the excellent cruising speed ) and the smoothness of the installation and the Henley 4 blade 'Black Tip' propellers.

To sum things up, I am impressed! You said that I would get improvements in speed and vibration mid-range and top end and I am happy to report that I have seen improvements right across the speed range. I picked 2.4 knots at my cruise speed and vibration was reduced by up to 40%, plus at the top end I got another 1.7 knots. The Stainless Steel "Wahoo" propellers I fitted to my Riviera 4000 Offshore had improved the boat so markedly that family and friends have commented on how much smoother the boat now feels. I would have no problem recommending these propellers to any of my boat-owning friends and will specify them as standard on any future boat purchases!!

The top end speed is exactly as the calculations predicted and these propellers have markedly more "bite" when manoeuvring than the ones I replaced, even in reverse. As a result, the boat runs better, cruises faster with less vibration and gets on plane 200 rpm earlier, a real bonus when cruising offshore in a decent swell.

Once again thanks to Henleys Propellers and to Twin Disc Pacific for getting it right first time and giving me the extra performance without the shake!

Launch went well yesterday, we had the Coastguard vessel next to us and they were going about 1 knot faster at 28 knots, then our engineer advised a short burst at wide open throttle. Although the electronics had not been commissioned, we estimate approx. 28-29 knots. The square planing board at the stern was actually on top of the water due to our very light load. There was no prop aeration at all which can sometimes happen with this hull shape as they are reasonably close to the surface.

If I can offer some advice, when choosing propellers, do not just get the cheap ones, both the Ferry and our Alaskan 41 have gone for specific propellers from Henleys in New Zealand, who are the experts in this type of full displacement hull shape. We work closely with Twin Disc who are their Australian agents..

"Several of our clients have now invested in Tiger Props, typically improving speeds across the range by 1.5 to 2 knots. With this performance we have decided to fit the Tiger Props as standard on all new contracts."

“Wherever possible we prefer to use Henleys Propellers as we have a lot of confidence in their product. We generally use Henleys Propellers on most of the boats we design for Australia and boats which are built in Asia. Henleys supply a good product and understand our vessels and how they perform which is critical to propeller design."

"We have found the tiger Propellers offer significant improvement over the conventional styles available in the past in smoothness, speed and economy."

"Naiad has designed and developed twin diesel shaft driven rigid hulled inflatables using complete Henleys drive lines. Each time Henleys speed predictions and prop selection have been accurate. It is most pleasurable when things go this well."

"Henleys suggested four blade Tigers be fitted to our new Genesis 400 Targa, they were right on the button. Better than predicted top end speed (33knts), really efficient and smooth through to mid-range cruise."

Chris Pollock,

"On fitting tiger Props to our planing launch we experienced a 2 knot speed increase throughout the engines RPM range. Maneuverability was significantly improved."

Tony Hembrow,

"We encourage our owners to fit Tiger Props on our range of power and motor sailing catamarans as they improve performance and economy."

"It’s been four years since Salthouse Marine changed to Henleys propellers exclusively. We were looking at reducing noise and vibrations caused by propeller wash, as well as improving performance and product consistency. The team at Henleys are great to work with and have been extremely helpful in developing and improving our product. Our results show their ability to work with us to get the best result."

"Tiger Propellers sell themselves. My customers now demand them. Their reputation for quieter and smoother running is to be believed.

"Skipjack Propeller" Just a note to say thank you for your prompt efficient service, the propeller fitted perfectly onto the shaft and we are extremely happy with the performance it provides. We can now comfortably reach hull speed with a power to spare. Sailing performance is greatly improved with no noticeable effect of drag.

"With prop fitted, new stern tube bearings and antifouling done, we took Ariana into the Pacific off Napier today.  Lousy weather, cold, fine misty rain and no-one else is sight.  But the boat and engine felt very good, like it never has before. Engine revs exactly on the specs at 2550.  So thank you and your crew for your skill and expertise!"

"I just wanted to let you know that the work you did for Salute was first class.  She is running superbly with no discernible vibration.

Thank you for a job well done."

"All the kit you supplied has now effectively circumnavigated the world more than twice with practically no maintenance of any significance required."

'The short Sea trials show that “Planet Solar” is like a brand new boat: maneuvering is so easy that the boat turns 360° on her centre, demonstrating she is like a toy in the harbour when docking! The torque of the electric motors is so huge that the boat (100 T) comes from zero speed to 7.5 knots in less than 300 meters... We have reached very easily the speed of 8 knots with a total Power consumed of 75 kw, which is 37.5 kw per propeller, at the running speed of 498 turns/minute on shaft line which looks to be a little bit better than the calculated curve. Everything is in total silence and no vibration. Today, the electric motors are still with the previous parameters of 40 kw, but they will be configured to the maximum power of 60 kw within the next 15
days.


So, I expect that the top speed could be in the range of 9.5 knots, and the economic speed at 10 kw per propeller to be about 5.3 or 5.4 knots. Many many thanks, Mark, to have supplied these two wonderful, Beautiful and very efficient propellers.
I really had no doubt about that : You are the best !
Congratulations to you and to all people of Henleys Props!'

"Hi  Mark.
 
I was in your shop half an hour ago with a prop enquiry. The guy who served me (I don't know his name, but from the counter his desk is on the right) was incredibly knowledgeable and helpful. I walked out very impressed by him (and therefore by Henley's).

I thought you might want to know."

Cheers
