This is so great, sharing your knowledge to make the sport more competitive! Maybe the most easy way getting a good speed out of your boat is the secret maths of engine height, prop choice and water conditions. We'd like to hear from you about this in the next video ;-) (Cause I'm still learning by trail and error)

@OXSEnterprises 4 года назад

Keep trialing. We have a few video ideas but myself (filmer/editor) and Brownie live at the other end of the North Island so the logistics are hard.

@inflatableboatracing699 5 лет назад

Great info, thank you. Keep it coming!

@OXSEnterprises 5 лет назад

Will do.

@RomanovDK 6 лет назад

NICE! Well done - keep 'em coming , please. Other topics: how to modify (the engine)?, how to handle torque (steering damper, elastic cord? ). How to right the boat in case of a "whoops" - What gear is required in the boat/on the person for races etc.

@OXSEnterprises 6 лет назад

Engines are standard. I think I have clips of the boat being righted so could do that. Safety equipment and what gear is needed is coming next week. Cheers.

What settings do you use on your tiny tach to get it to read correctly?

@federicomontoya6861 3 года назад

hey man! would you mind making a vid on transom, mounting, trim angle and propellers? or share any book i could use? I am having trouble with a 40 hp yamaha on a 13.3 feet inflatable. thanks!

@nicholaszamelis9471 3 года назад

How long I’d the prop typically?

@idoplaythis788 4 года назад

But how is your engine so high? My outboard already ventilates when the cavitation plate gets above the waterline.

@russoley8995 3 месяца назад

old video but I am wondering how fast you guys go ?

@alphashot3910 2 года назад

Would there be Thundercat racing in NSW or near Sydney

@4JesusRace 5 лет назад

whats a good starting point for prop height,,, is the the center of the hijackers a good place to start with center of prop hub the same as the center of the hijacker im about 4 inches below that it shots water back in the boat also i do leave the trimtabs( the lip on the back of the transom alone or do i want to tweak them some up od down

@daddybot 5 лет назад

Depends on your hull type. A thundercat does not have trim tabs, you may mean the cav plate which is not adjustable. The prop shaft in line with the hijackers is as good a starting point as any. Basically you move up and down, looking for between 6500-6800 rpm with a fairly steady tell tale. Then start trimming in and out using a gps and rpm to find the sweet spot. Its all about trial and error, lots of it...

@KVANTdoo 3 года назад

I've been checking your channel if there is something new, but no more. Will you do more? I would like to se video of setting (height of the motor and trim and the best aproach to that). And maybe how settings changes when using different props (Cleaver, bunny ear, semi-cleaver) with different pitch.

@OXSEnterprises 3 года назад

Not doing anymore sorry.

@josephmannphotography 6 лет назад

What pressure do you run your chambers? Out here California we see temps of over 95f/35c and our boats develop seam leaks. My boat is older and I know I am going to have issues over time. Do you have any recommendations? A new boat is not in the cards so I am playing the cards that I have! Stabond is my new cologne!

@seumasmacleod1322 6 лет назад

You can use liquid latex inside the tubes, helps seal up wee holes in the material. Just pour it in through the valves then roll the boat around to cover the inside of the tubes

@OXSEnterprises 4 года назад

I wouldn't have a clue mate. Not sure if anyone is really onto working the 30's

@darrenicon5172 Год назад

Hello nice vid. I just got a 40hp merc/Tohatsu with 40hrs as new can you tell me how to make it 50hp as the bore and stroke is the same. What do I change to make it 50hp. Thanks

@OXSEnterprises Год назад

Sell it and buy a 50.

@davidhorwood6075 4 года назад

Any advantage/disadvantages of mixing 98 compared with 91 fuel on a mid 2000’s Yamaha 50?

@OXSEnterprises 4 года назад

No advantage. Everyone who races uses 91. May be advantage with a mod motor.

@FreddyGre 4 года назад

Could you guys please do a video about engine height. With my cleaver I only go 60 kph and I think its because of that... Would be awesome

Will try.

Stops the motor starving for fuel.

Yeap. We don't have a tutorial but I'm sure you can find it online.

@RY4NP 6 лет назад

Any rules on fuel?

@OXSEnterprises 6 лет назад

I feel we should've touched on that. Fuel must be pump gas from a service station. No additives allowed except two-stroke oil. Recommend fully synthetic oil, do not use ethanol gas like at Gull as it will attract water and clog up carbs when racing.

@RY4NP 6 лет назад

OXS Enterprises i raced rubber ducks for s surfclub here in oz back in my teens and im pretty sure fuel was regulated, but you could always smell that sweet avgas in the air.
