There a guy who is doing the same in chch. he?s had too do some head scratching to get the SJ unit too fit in the transom.  But im pretty sure hes got it sorted.  PM me and ill give ya his details.

Thanks guys i intend to push on with this as my off season is quite short.still do 40-45 hrs but slacker than normal.
i have measured the transom and yes will need modification to fit a SJ.

I see other manufacturers that do biz/raex  often use thinner delta (5-6 mm) and thicker biz (5mm?) With 3mm biz will it still be dent-able or with 10mm underneath it will be all good? Is it some super hard grade?

Not sure how easily it will dent.has to be better than nothing.in some ways I think steel only makes it slide better.think it 3 or 4mm unsure what grade. I asked Mike at Lvb for the option, he said he hadn't done it for bigger hull before so will see.

Good to see you put the sides on the right way.....arrows pointing to front

Yeah thanks.not sure how well it will plane up this way tho.

It looks like you have welded the sides to chine before tacking the capping and foredeck on?
Or an I seeing things?

Yes as per instructions. Have flipped hull over now.do you do it in a different order?

Tacked front on and started fitting up the transom. Fit seems really good so far no trimming. Few stern words when fighting with the front on my own,not enough hands

What model tig and where did you take it for repair.

hi it is a cigweld weldskill 200 acdc tig.hadn't done much work at all.took it to a guy in Timaru he told me the inverter was stuffed $1600 for a new one. i replaced it with a BOC 200acdc for less good welder at this stage....as good as me anyway.

That is a big pump, must be pushing close to 80kg? Is it 8" or 8.5"?
What's the engine specs? Is it the oldschool strokes 308 or the last of the Holden 304/185kw donk before Holden went LS1?

Big pump 8.5 inch.304 holden stroked to 355ci or 5.8litre should be around 550hp.alloy heads efi etc.will post up weights as I go soon.

Theyr 95kg.  Flopro is 60kg

Yea ive used a few harris marine trim and reverse setup now. Theyr 10/10  For people that dont know, when you pull your reverse on it auto trims up ya trim/tilt nozzle.  This makes it so much more simple for everything,   Everything is very well thort out, theres bearings instead of bushes, nothing binds up, theyr setup for scott or hamilton or southern jet.  (They wont work where a older teleflex has been used tho).  Theyr also got friction adjustment on the trim so you can make it stay put. And mikes price includes all the mounting hardware needed.  Cables and mounting points. Think theyr just over $1000 including gst

My 2c is when setting them up use a 40series cable.  Not a 33c cable.  33c is fine if your a lake boater.  But if your a little rough like me and ya go bush bashing and spends plenty of time pushing things to their limit use a 40. Also with some trim nozzles when theyr full trim down and you steer too the left it puts weight on the cable, ive seen a heep snap.  Also they sometime jam up with gravel and the 33c cable wont budge it without bending

We have been making brackets to drop them down past the gunnel.  It makes them easier too use and keeps ya hand away from the windscreen.  It also keeps the mechanism clear of the steering cables.

thanks for your input JohnR ,i will take your mounting advise for the 40 series cableand look at the position.the Harris gear looks like the business.i ike the look of the steering as well with independent pullies for alignment.
cheers will update soon

Post by: Warwick Marflitt on July 16, 2021, 19:30:22 PM
Just have to add the weight of the water that'll be moving inside it. About 60ltrs= 60kg?
Title: Re: LVB4500 kit set build
Post by: APE on July 16, 2021, 21:54:35 PM
Yes it is heavy.but I'm a lot heavier than that.and can't paddle that much water.will definitely be putting alot of effort into the balance of the boat with fuel etc
Title: Re: LVB4500 kit set build
Post by: Warwick Marflitt on July 16, 2021, 23:03:54 PM
It will be a great boat and it will be your hand built creation. Crack on it's looking awesome...

So today's mission is to do something about this.small issue of the jet unit not fitting the transom.i knew when I decided on the unit and this hull I would be in for mods.i talked to Mike at Lvb he said he has seen the portifilo deck sectioned on the underside for clearance underneath,above unit.am unsure if I will try that or just cut it straight up for maintenance access.
Title: Re: LVB4500 kit set build
Post by: APE on July 18, 2021, 22:20:34 PM
So that happened slowly. Bit of a mission. As you can see I cut it right out. When I put a cover over the unit I will make it flush with the deck then out over the unit in one piece.this will be easy to access and work on.

Don't think it will look to bad once cover is on

Very tidy, a good solution. Well done for thinking about servicing access, that can be easy to overlook.
