BB's go fast SIB !

Bus_Boy · 10 September 2010, 14:00

Thought i would get some pictures up of my current toy. Due to lack or storage space, anything on a trailer simply wasn't an option.

In a bid to satisfy my go fast needs, a Zodiac Fastroller 2.85m (9.35 ft) tiny isn't it? was aquired. I then picked up a 97 Tohatsu 30 HP.

Currently re-painting the motor, doing a few changes.

Plans to make a new thicker floor, new transom, and add some hi-jackers.

Goal is 70 km/h , which should put the wind up a few other's at the local dam !!

More pictures, sorry about quality, most of them came from my mobile.

Bus_Boy · 10 September 2010, 14:12

Fixed that nasty chunk out of the skeg.

Interesting. Will keep an eye on the Darwin Awards website for updates.

That should fly, looks good

Bus_Boy · 15 September 2010, 09:04

Darwin awards, that's not very nice

Finally started applying the paint. With my limited space, and a 16 hour reccomended drying time between each coat, it's going to be a very slow process.

Black is going on nicely, pan section i completely stuffed up and will have to re-do. I didn't know that their is a chemical release process with the primer that must sit for atleast 24 hours.

Bit of an update, i'm not finished yet, but getting close. The motor called for a bit more work than i was originally planning so it has set me back a bit.

So far i have :

- Fitted solid alloy mounts top and bottom.
- Replaced the top and bottom swivel tubes bushes, thrust plates, and fitted new o-rings.
- Fitted new transom brackets.
- Fitted new tilt tube, and new tube bushings.
- Replaced impellor, top and bottom gaskets, fitted new stainless screws.
- Replaced bearing carrier oil seal.
- Fitted new pan seal, new pan bolts, rubbers, and spacers. Completely
sealed pan section of with sikaflex.
- Replaced power head base gasket

So far modification wise i have :
- Driller 4 x 0.75 Inch holes above cav plate for exhaust releif.
- Removed tilt mechanism and shallow drive unit to shed unnesacary weight.
- Fitted PowerTech SRA 10 in 10 P propellor.

Future plans :
- Remove starter ring gear and lighten flywheel
- Fit Boyosen reeds.
- Experiment with different length velocity stacks

I have ordered a new cylinder head gasket and i am looking into how much can be machined off in order to gain more compression before fitting the new gasket.

Starting on the new floor this week, i'm going to have to experiment with some different sized off cuts, to find out how thick i can go with the floor boards.

I'll also be coming up with a way of securing the fuel tank both at the front and rear of the hull.

Solent-Salted · 26 October 2010, 11:26

Yowch,

That thing is going to be a missile!

re the transom and a 30hp..... is there too much weight there?

Bus_Boy · 26 October 2010, 11:52

Most likely too much weight yes.

The motor weighs 52 kg, maybe a tad lighter now, the transom is rated to 50 kg. So it's right on the limit either way i look at it.

I plan on attaching some extra D straps and fitting some bungee straps between both the floor and the transom, and possibly the tubes.

I want to reduce the forward and backward flex on the transom, without making anything too rigid and putting too much stress on any one particular area.

Solent-Salted · 26 October 2010, 13:15

Fair enough,

I'll keep my eye open for you as the first aussie into space

Bus_Boy · 09 December 2010, 12:43

Cylinder head now ready to go back on. I also had to order a new tiller handle as the original had snapped off under the rubber grip.

I finally got around the repairing the cracked cowling. I really dislike working with fiberglass, but i think the overall finish isn't too bad.

Everything is ready to go for a first trial run. I'm just waiting on a replacement coil pack, then a quick check over everything and fingers crossed i have put everything back together properly.

I'm liking this new trend of making good use of the living space

Now I see why "open plan" is becoming so popular

Bus_Boy · 10 December 2010, 11:32

Things are easier to find on a white tiled floor

Too late! I have a habit of taking my work home with me...on the soles of my boots usually

Bus_Boy · 11 December 2010, 14:07

Ok so i had to move everything outside as my living space is now taken up by some seats out of a plane.

Somebody said i look like a fish out of water

theboysmiffy · 15 January 2011, 13:47

Any updates on the project? Did you get to replacing the floor?

Cracking idea.

Bus_Boy · 16 January 2011, 01:26

No updates, yet, i put the motor back together but it isn't starting.

I haven't made the floor but i have made a template up and measured the cut out dimensions.
