I just ordered a navigator 3 meter. The maximum recommended motor size is 10 HP. Before watching this video, I was thinking about getting the 15 HP anyway, even though it is larger than recommended. But seeing you run the discovery 330 with the 10 HP, I don't think I would want to put more than 10 on the navigator 300. Thanks again for doing this. Would love to see more navigator content.
Love that new color scheme and hope to get the Discovery 4M ordered in the US in that color shortly. Will be pairing with a Suzuki 20HP EFI manual trim and start. Same weight as their 9.9.
Excellent video, thanks! Would love to see a video with the same 3.3m and one of the newer electric motors in the 1kW range. Also tests with the Tactitian and the 1kW, 3hp 4stroke and 6hp 4 stroke would be appreciated.
I have a Tactician and a new Yamaha 4hp 4 stroke. Returning from a camping trip this morning and the water was as flat as. So....flat out 16-17 km/hr (I'm 80kg, about 25 kg+ camping gear). Most of the time I'm happy sitting at about 8 km/hr at minimal throttle open. Cheers.
excellent video, congratulations for the information you give 👍 I would like a 9.9 4-stroke but I always transport the engine on every outing and therefore it would be difficult for me due to the weight
We've had our True Kit Navigator for 2 years now as live aboard cruisers. Unlike the demo on the Discovery, a 4 stroke 6hp will not plane with 2 people but that is easily fixed with a 9.9. The only real downside is how wet a ride it is in any kind of chop or swell.
10:51 if you add cupping try going down an inch of pitch from the stock prop , the decrease in slip factor will make up for some of the loss of top end and the holeshot will be much improved. Try it on your fav outboard , it usually works in my exp esp for tunnel hulls where you can jack the outboard to run the prop in a surface drive type environment which the right amount of cupping allows you to do.
Wow, I'd really like your video. It's really helpful for those beginners like me. I did purchase a discovery 4.0m last year 2023, but I haven't play with it yet. In fact, I did purchase a 2024 Tohatsu 20 HP MFS20EEFTS Outboard in the same year with my discovery 4.0m. However my outboard is really heavy to me & I haven't break in my outboard yet. & therefore my discovery is still in its original box. Your video helps beginners like me to have the idea what size of motor I can use with their inflatable boats. The inflatable used in your video clip is Discovery 330. It will be a great help if you can repeat your tests with Discovery 4.0. Big thank you from WA, US.
@@abefrancis4137 If you're using Tohatsu, there's no big difference in weight between 9.9HP vs 15/20HP. 6.6HP version is really ... light. I just see a Tohatsu electric outboard Tohatsu Alaris 6.0KW. According to Tohatsu, it's comparable to Gas Outboard HP 9.9HP. Its weight is 32.0kg (70.5lbs) with built-in GPS plus Power Trim and Tilt features. However that outboard is really expensive, It's now available at about $8,600.00.
Awesom! I have finaly decided to upgrade from my torqeedo to a 6hp and have been trying to figure out which 6 would be best. Is there any reason why you went with the yamaha 6hp?
Nice test. The Yamaha 15hp 2 stroke has proved optimal on my 330. The Tohatsu 8hp 2S I had before was good, but the Yamaha is that much better for torque n power to weight. Hard to find in Uk though. The 9.9/15/20 Tohatsu 4 strokes, though lovely, are just to heavy to lug on and off for my 60 year old bones.
Any plans to replicate this test with a 15hp Yamaha 2st with Permatrim fitted? I’d be interested to see the difference between the std 9.25 x 10.5 prop, a cupped version of that prop, a 9.25 x 9.75 Ali prop and a 9.25 x 10 SS prop. I’ve seen the Rokkit 15hp Merc prop vid and the difference with the 9” SS prop. A Yamaha test would be great if you had plans to do this. Cheers.
A Permatrim will knock a tiny bit off the top speed. But you can make gains in other areas like faster to plane, lower planing speed, better handling and steering which are worthwhile. A cupped prop has almost no disadvantages also
@@TRUEKITINFLATABLES yes I will get a cupped prop. I still get prop slip even with the permatrim. I notice people using transom risers which apparently help as well

Thanks for the great video, answered many questions I had. Looking forward to my new Navigator 3.3

Thanks for the input. We will get to the Tactician and do some similar demonstrations soon!

The power vs weight is an age old issue and there is always a compromise to make. Sometimes less speed is worth accepting to save your back!

Not going to argue with you. Everything you say is correct!

Same. Would love to swap the 15/20 for a lighter 9.9 on the 4.0

We will get a chance to demonstrate with a 20hp soon! Those would be only for the Discovery 400
This was a really great video. Thanks!
Glad you liked it!
Great video - how do you think the smaller 2.8 Discovery would go with those motors?
Great review. Thanks
Awesome stuff 🙌
Thank you 🙌

Will it still plane with the 6hp without the fin thing? What size prop was on it and was it cupped?
Hey good test .What pitch is on the prop tho? I would think 9 in would be best?
A cupped 8.5 inch pitch would be my preference and what we used here
right on, good info
Good to see your sticking to the 5 knot rule 👍
Thanks 👍
Did the permatrim affect the top speed much?
A Permatrim will knock a tiny bit off the top speed. But you can make gains in other areas like faster to plane, lower planing speed, better handling and steering which are worthwhile. A cupped prop has almost no disadvantages also
