Hi Gareth
before you go making anything just try dropping it two bolt holes, should take to you a few mins and seeing if that makes any difference, its a no cost test.
Mine was set up like yours for height and it needed dropping a bit.
Easy way to adjust it is lift the front of the trailer up put a block of wood under the engine leg to support it, remove top bolts and slightly loosen bottom ones. then slowly lower the front of the trailer until the bolt holes you want to use line up then a dob of sealant and bolts back in an tightened

Thanks for all your responses

I am going to order a Aluminium Yamaha 10x15 G (Lip cup) prop and see if that makes it a bit quicker!

Yamaha also do a 16 and 17 pitch prop but these arent lip cup - whats the advantage of the lip cup??

Going to order the 15 this afternoon unless people think I need to go larger on this very light setup??

Also Ive been advised to drop the engine so the plate is 1" lower than the keel.

Cheers

G

I am no expert but I would not drop the engine, it already looks much lower than where we are running our 25HP on the Mark IIc and we get 34mph.

With regards the Futura Sport they were faster, as the speed tubes were much bigger and hence lifted the boat further out of the water reducing drag. The fact that we were running a short shaft 50HP would also help. As for the magic 50mph got there a few times with a light load and the wind behind us.

Thanks for your response David.

I guess your 2c is a short shaft and the older shape with pointed rockets? Be great to see any pics you may have showing where your anti cav plate is in relation to your keel on 2c OR futura sport!

In 2003 they changed to the new shape futura with huge main tubes and hull profile and speed tubes the same as the old futura sport!! They did this tube size increase to allow for the new heavier four stroke outboards and therefore the boats take a long shaft and zodiac recommend that it is mounted so the anti cav plate is level with the keel!

Im trying to get futura sport (now discontinued) performance out of my new large tubed even lighter Mk2. Hence the pull start / manual tilt / 2 stroke light Yamaha 50H!!

I would really love to know what pitch prop you had to do 50mph?? Zodiac claimed the sport would do 60mph with the right prop! Im changing from 13 pitch to 15 to try and get better than 30mph and get top revs down as boat is so light!!

Any advice / pics / suggestions most welcome.

Kind regards
Gareth

Futura Sport Mark 2

Looking through my brochure boxes, I have come across a Zodiac 2003 one. Here is what it says:

"100% PURE ADRENALINE

The Futura Sport is guaranteed to make your adrenaline flow. The speed, up to 60mph*, is simply incredible and piloting requires all yuor concentration. The sensations are like those of an off-shore powerboat racer. Despite this brute performance, Futura Sport remains very comfortable with the Futura hull absorbing bumps and giving smooth and predictable handling. Spacious and well equipped, this racer also makes a good family boat and ensures you get the maximum out of even modest outboards.

*Fastest speed for the class acheived by a professional team using a 50hp motor and a special propeller. NOT TO BE ATTEMPTED BY NON-PROFESSIONALS"

Overall length:4.20m
Weight: 101kg

Ask dealer for prop pitch

In the same brochure it states that the Mk 2 Futura S does 37mph max. Will try to get pics of brochure online!

Hope this helps! - dunno how.

......what is this magical 'special' propeller!!??

Someone must know about this Zodiac fastest speed in class title and what setup they were using! ;o)

As in theory my setup should be just as light with the same engine! It must have been a highly tuned 50hp - and a jocky on the jocky console!

Cheers for the post

Gareth
