Mike on "Another RiverPro hits the water"

Mike — Sun, 05 Feb 2012 04:23:07 +0000

Thanks, Yes they are lifting hooks. We were cruising up the river at 2800rpm so at that sort of rpm the lexus should return around 16 lph or better, A small block chev doing the same thing would be reasonably economical as long as it was tuned correctly (most are not). But a carb cannot compete with fuel injection when it comes to throttle response and fuel economy

The guy that came for a test drive made a common comment that we get with the lexus on the southern jet 8.25 two stage, which was that he couldn't believe how good the lexus is when matched correctly with the jet, he made the comment that other boats that he had been in with the lexus felt very ordinary and he didnt rate the lexus much........until now. This guy has owned and driven a number of boats

I have the boat available over the weekend if anyone would like to see the performance of the hull

Here is a boat that we supplied hull/jet/seats and some bits and pieces as well as tuning the computer.

It is a short little boat but we kept the Chine width wide to make it a super load carrier, The owner is a professional hunter and needs a small boat with good load carrying ability.
The jet is the Southern jet 8.25" two stage with trim nozzle, motor is the ever reliable Toyota Lexus V8 with our manifolds.
I finished the tune today and managed 85km up stream and 92 down with myself and a full tank of gas. Awesome handling with ultra soft ride and slow planing abilities with precise handling at speed.
The Lexus is the perfect match to the Southern jet 8.25 two stage and pulls 5200rpm WOT and cruses at 3200rpm ( clean slow plane is 2400rpm) giving good top end punch

We are under way with the demonstrator, It is to be a 440 RiverPro (router cut)alloy trailer/southern jet 8.5 two stage and 6L LS pics soon.

Mike on "LS3 with factory fitted hot cam"

Mike — Thu, 26 Jan 2012 04:22:04 +0000

We did the tuning and set up of the motor with a good set of tuned headers, then we did a power run with the cast alloy marine manifolds and lost 40hp against the headers

New manifolds are not far away, the pattern maker is working on them as we speak

boatie — Thu, 26 Jan 2012 02:24:45 +0000

Interesting. Somehow i was under the impression it might gain 20hp without standard car manifolds but i have been wrong before.How far away are the new manifolds which look good by the way.
Thanks.

Mike on "LS3 with factory fitted hot cam"

Mike — Thu, 26 Jan 2012 02:01:59 +0000

We dyno tested 6l 550hp LS and lost 40hp with marine manifolds, We have new manifolds being made that should seriousally reduce that

Hi Mike

I bought an LS3 from Aus with a factory fitted hot cam. It is sold as a 480hp engine but wondering what the hp would be once i put marine manifolds etc. Thanks

Do you have a photo of the grill?

It is made to take the jet ski front bearing housing and shaft.

We have purchased a Yamaha 11000 jet ski and we will be transferring the gear into a RiverPro 3.1, We are planing on using this intake that is large enough to run a full grill without issues,

Hi,
No chrome headers, Mike is going to supply ali high raise ones with a custom snigle centre outlet above the jet unit.Approx 200 x 50mm
Like a large letter box slot. Needs to be above the water line due to the big cam.
Full engine cover to keep the big water out.
Same wee Chev and 3 stage I ran before.
Just a little quieter and a few horse robbed with the exhaust.
Should go OK as not a lot of difference in hull wieght, but this one should trim out a little better.

drz-400 — Mon, 16 Jan 2012 08:16:36 +0000

Funny you should say that....we are doing a 3.1m for our jet ski gear using a cast alloy intake that we have sourced

blondeone on "NEW RIVERPRO BOATS"

blondeone — Sun, 15 Jan 2012 20:41:29 +0000

Just thinking ahead,it's a worry I know!
Could the drawings be reduced to produce, say a 3.6m hull?
Thinking jet ski power.160 hp 4 stroke.

Looking good Mike.
The painter is going to love you.
With the use of full sheets I can already see a cup of bog is going to be too much when it comes to prepearing the hull.
Very cool.

Apart from having a passion for jet boating, I spent over 8 years in the earth moving industry carry out sub-division work, farm tracks, water race construction and repair and pretty much anything involving a digger and truck. After the first earthquake in September we thought that jet boating would not be a priority for most people trying to re-build their lives after the earthquakes, so we decided that rather than risk not having the work to sustain our workshop and staff that we would diversify into another field that I had experience in. In April we purchased our first truck, a Volvo F12 6 x 4 Tipper which pretty much went straight into work helping to carry out stop bank reconstruction. Then in October we had the opportunity to purchase a second truck which is a CH Mack 6 x 4 Tipper. We now have full time and part-time drivers and you are likely to see our purple trucks around Kaiapoi and the greater Christchurch area. We are available for bulk cartage, spreading, silage, subdivision work and also digger work available on request. We have reliable, experienced site safe approved drivers.If you need trucks Give Mike a call 0275 767 227 or email on hmrtrucking@yahoo.co.nz

No but thats a good idea, The main engine bearers just slot in with no trimming. then the top sides and then the top deck, it really is great how it all fits together. pic of the template that marks where the screen sits prior to welding. All the welding is done up the front before the deck goes on.

Thanks Mike.
Did you cut the deck frames out like the jig so they all sloted together?
Would make it easey for the home builder if it all could be put in place, support it self and then be tacked.
Its coming together nicely.
