They did look super cute together, and that's the most important thing. Pity J5 didn't get the Jimny in green as he originally wanted, that would have been adorable.

m8 send it over, il spray it

How about Skip

I'm pleased to announce this boat has successfully completed stringent reliability and performance trials including but not limited to...

Shallow water performance

Low speed maneuverability

Higher speed spins and dicking around

And some photos to stick on the fridge

So yeah, as seen above, took it back to the water yesterday and it does run a lot better when its not breathing its own fart cloud.

I'm not completely happy with its performance though now its making full more power, it doesn't 'bite' the water like I would expect, if you feed it more power than it can shift water, it nangs out and feels slower than if you were to nurse it up to speed. You can see/hear this in one of the vids.
It handles a quite loosely, but I don't have much reference to compare it to, aside from the donor ski which carved corners like a water-skiing cut cat, comparatively. 
If you do manoeuvres that are too aggressive or any spins it comes off the plane pretty easily and doesn't pop out of the water like the motor seems capable.
So next step is to look at the spare jetunit, if its any better pop it on for testing, and I feel I'll probably wind up giving one of the pumps a birthday.

Cute

The more I look at this thing, it never stops looking awkward as shit. Luckily you can't see much boat when you're sitting in it I guess.
God its ugly.

Do you know what the specs are on the hull? Is it flat or have planing strakes? A lot of fibreglass boats handle loose as the have a shallow v to run in less water, old Jet44s were pretty slippy.  Alloy you can get away with a bit deeper v since not as scared of rocks an strakes make a hell of a difference 

[johnnyfive]

Not really, I'll try and get a photo at some point, it doesn't have many features if I remember right, aside from many scrapes and marks in the plastic.

So yeah, after googling what wear rings are supposed to look like, and frowning at the pump from the donor banana ski, yesterday I removed the pump from GreenWaste and had a look.

Two pumps on the floor, pretty much identical.

I believe this is what a bad condition wear ring looks like, from the donor ski. Cracks and grooves, not toight.

And this is what the Greenboat had in it, note the missing material around most of the diameter. Lots of clearance.

So I figured bad was better than worse than bad, so gooped it up and bolted it back on.

Sploot.

Launched it into the harbour this morning and pootled about with VG and Keltik, it still doesn't feel 100%, but its pretty usable now and hooks up and pisses off quick enough for me. I will likely order some bits and pieces to tidy up the original pump and probably swap it back in the winter perhaps.

I'm waiting for a China GPS speedo, and need to fit a hour meter/tacho, fit some latches to the hood, attach the paddles in a better way, and I think that'll do for now.
What a novelty having a working toy

[johnnyfive]

Also, I think I'm pretty settled on GreenWaste as a name for it, although am still considering TrashBoat. 

Trash Boat which is fuelled by Bin Juice.

"pond scum"

GPS plotted a path of some of our journey yesterday. Stupid tide running away from us though, there only seems to be a couple hour window where you have useable water depth.

Suuuuper keen to try get up the Nukuhou River/stream at some point. Guess you would have to start an hour or so before hightide? I was quite surprised how quickly the water fucked off. 

[johnnyfive]

Yeah that would be my plan I think. To get under that low bridge, leave as soon as there is enough water to get up there

[johnnyfive]

Would give you more water up the top too hopefully

[johnnyfive]

Fitted a China cheapo hour meter tacho device the other day. Went out for about an hour last night, still don't have the nerve to hold it WOT for an extended period of time (because questionable twostroke). Seems pretty happy on the plane at 30-50km/h, did squeak it up to 60 at one point, has more in it, but I didn't have anyone to tow me back to the ramp if it shit itself. I imagine a bit more speed will be unlocked with an efficient pump. 

Around 4Krpm at 40km/h ground speed (plus or minus a tiny bit for water speed). Seemed around 7Krpm for 60km/h. Bad footage is bad.

I still don't know where to set the variable trim on the nozzle at different times, I find myself adjusting it all over the place with only very minor effect felt.

Only travelled about 3k out of town, but covered about 26km in total on the return trip. Had to slow down a lot in order not to swamp swimmers/kayakers/rowers/fishermen/ducks.

Good fun though, just need more time available, and maybe to carry some extra fuel, it does seem to hoon through a reasonable amount.
