hi, i have been offered an ls1 corvette motor with loom and computer.what would it cost me for manifolds ,heatexchanger etc to retro fit into an alloy hull? also could it be run through a 772hammy untill i get another stage im not after a rocket and is 3500k a good price to pay for an ls1 with just over 100k on it Cheers
computer and loom are factoryManifolds are $1650
one of our heat exchangers is $650+
Drive block $145
Modify Loom with all fusing/wiring for dash etc $450
Computer tune $450.
You can do it on a two stage with the right impellers but you really need 3 stage.
$3500 seems about right.
Mikethanks i guess a hi pressure pump and a few sundry bits would be needed too

They have the thermostat on the bottom hose if I remember correctly....If thats the case then the only system that works correctly is the constant flow pririty system, We make custom ones to suit but due to the cost of the thermostat it makes them expensive (around $550) If you can find a SCS (Stevens cooling system)box 2nd hand then grab it as it will work perfectly.

Hi chaps, just a bit of feedback on the ignition miss I had a few months back...The leads resistance tested fine...turns out it was a very old and eroded set of rotors...I will be running the boat properly this weekend to comfirm but I'm 95% sure that was the prob as it sounded good being run on the trailer....will keep yall posted.

Greetings of the colleague! I from Russia, live in Moscow, and in holiday I go to Siberia on the mountain rivers of Sayan mountains. At me to you some questions:
I wish to put on the new boat the engine 1UZ-FE from Lexus. It will work on Hamilton 772. How correctly to make its conversion? Whether it is possible to order in you accessories for conversion of this motor?
Prompt what expense of fuel will be with such complete set? What speed it is possible to expect with it? A boat at me Custom 5.35 2.04 width is long. On the bottom there is a hydro-ski.Yours faithfully Vlad.

Hi Vlad, I have received your email and welcome to the web board. The Lexus will work well on the 772. With the Lexus and 772 our boats will do 90 to 95km on the river and use between 18 and 24L per hour.
It is no problem to send parts to you and I will send you a list by email. Have you got some Photos of your boat :-)Posted 14 years ago # -
Thanks Mike!
Mail with the prices has received. Now I think as it is all to pay and quickly to receive.
There is a question? And in what difference of the regular computer of engine management of what at you? What will it give and than it is better? At it the special program? (Insertion)
I ask because there was no experience with such motors: ^)
Fuel consumption, what you to me have told at what turns (PRM)? And what at this motor a cruiser mode? What impellers are optimum for this motor? What else you can make the recommendation on jet unit and to the motor?
P.S The boat Photo while is not present, we only have started to build it. I can show only sketches. As we will construct necessarily I will show!
Yours faithfully Vlad.

Hi Vlad, The car computer will not work in a boat because there is too many functions in the computer that need to be disabled, The motor will run but not well.......
That is why we us an after market computer. The one I supply is programed to run the Lexus engine.
The Lexus will rev to 5200rpm on the 772 and cruse at around 3500rpm. You may need a custom impeller for the jet unit (just the front one) And these are $695 NZMike

Привет Майк! Спасибо за ответ.
У меня вот такая колес. За какую скорость я могу рассчитывать с ними?
Я знаю, что Скотт делает для колес 770 серий, что о них можно сказать? А что колеса на вас? Я на форуме у вас их не видел.
О вашем компьютере я понял. Мы здесь с друзьями мысль о расходе топлива, что вы сказали о Lexus. Есть сомнения, что в таких поворотов и скорость будет такой счет? Это не достаточно для такого двигателя.
Можно показать, компьютеры, которые вы предлагаете, и колеса?I was never good at other language at school (I have enough trouble with English) :mrgreen:
Can you translate for meMike

Sorry Mike! :oops:
Thanks for the answer.
At me here such wheels. For what speed I can count with them?
I know, what Scott does for wheels of 770 series what it is possible to tell about them? And what you on wheels? I at a forum at you them did not see.
About your computer I have understood. We here with friends thought of fuel consumption that you have told about Lexus. There are doubts, what in such turning movement of movement and speed there will be such account? It is not enough for such engine.
It is possible to show it, computers which you offer, and wheels?
Posted 14 years ago # -
Wheels??? do you mean impellers? We have done just over 100 Lexus motors for jetboats and fuel consumption is in the range of 18 to 24 LPH, some have seen 16 LPH at a constant cruse of 3500rpm for one hour, But normal river boating should see under 25LPH

YES, impellers!
Certainly pleases if there will be such expense as you speak, I think you in it PROFF, to you is more visible. You have not answered about mine impellers? How they will be with Lexus? There is at you a photo of the computer and new impeller to me on replacement?

Here is the answer Mike commented in our forum Engineer-hydrodynamics (SKR) on consumption of motor Lexus:
"In 3500 prm -32-34 l / h, with 5200prm-64-70l / h, is the average consumption! jet units anyway, full boat, or empty, this does not screw his work load depends weakly. Think for yourself:
If 3500prm still can count on the specific consumption 220gr/hp/h, then at 5200 prm, is at least 250gr/hp/h - translate it into liters and get 0,282 liters / hp / h and 0,320 liters / hp / h . respectively ..
And now we substitute the force is approximately 100-120h.p. and 200-235h.p. and obtain 28,2-33,84 l / h for 3500prm and 64,00-75,4 l / h for 5200prm. And no tales ""We are horrified by such a fuel for this engine! :(

Sounds like Vlad needs too find someone who speaks english that you can phone or visa ,versa. I myself would far rather talk over the phone when its such an important issue.You can answer here. I want to hear comments on the replacement of my STD impellers at a more efficiently, to reduce fuel consumption and PRM. On other forums I read that the Lexus is more suitable for the 773 model it works more economical engine, retaining the same velocity. Is this true? What you should pay attention to? What is preferable Scott or Kodiak?
Vlad..

Hi Vlad,i have lexus powered alloy boat 4.45 metre.scott 8" 2 stage unit with 108mm tilt nozzel.Standard scott impellers. you will use between 18 to 25 litres fuel per hr. general boating. max rpm at wide open throttle(wot)of just over 5200.top speed of 87 km per hr. FACT.
