But the purchase price is coming down and findability (new word) of these engines is going up fast. Plus they are turning out to be very durable, and improve CG greatly when replacing big blocks. As such, they are gonna take over the market for marine engines. 454's are gonna be cheap and hard to sell real soon...

@ezstriper;
Perhaps it is such situation in USA. There in EU cost all engines like hell. If I marinise this engine, will cost me less than 14.000,-$ include taxes. Ok, I will need to be extremly creative to avoid strictly EU regulations, but it is possible. I want to buy Kodiak LSA or LS 6,2L DI L86, but no chance, they have no certificate for EU and it is impossible to import one of them in EU. Finally I am find LS3 from Marine Power which have certificate and imported in EU will cost me 19.999 $ include taxes. But today I am find this LS3 480 hp in England. I know how to marinise it, it will cost me less than all other engines and will have 480 hp with great torque (If it is curve on web page reall.).


Look:
- 400 lbft torque at 2.500 rpm
- 475 lbft at 4500 rpm
- 425 lbft at 5750 rpm

- 300 hp at 3.000 rpm
- 400 hp at 4.500 rpm
- 480 hp at 5750 rpm
- at 6.000 rpm still powerfull
And all this for 14.000$. It is not expencive if you ask me.

Nevertheless if I faill will losse 14.000$. Please instruction is this engine good base for marinise, or better to take 430 hp engine?
What mean in reall this 480 hp in compare with 430 hp at BBC?

Few of us have any feel for price and availability your side of the atlantic. I would stick with what is easy to get and replace...

More or less same storry. If break something bigg-finish for this season, nobody keep such parts on stock and must arrive directly from your land, but small parts are available every where. More easy is to buy Chevy automotive parts than Mercruiser parts. And marine parts from Mercruiser or Volvo really cost a lot!

dereknkathy

Mercruiser parts are Chevy parts with black paint on them. For the most part. What do they use in Europe that is not a Chevy V8? Or basically nothing, because they're all small engines for 35 mile-per-hour boats?

We have there all small block and bigg block which have EU certificate. Mostly in reed for Volvo and black for Mercruiser, but in specialised marine shop cost spare parts much more than same automotive parts. Market in my place is not so bigg and all unusuall parts must come from somewhere out, bigger expencive parts come directlly from USA or from magazine in Belgium or Neatherland.
For example peopeller Maximus cost in my region more than catalouge price in USA plus taxes and cusstom and no go to buy it in one week. More easy and much cheaper is directly personall import from USA...

Nevermind, I am not expert for purchase and forget this complains. My interes is to buy quality engine.

Hello,

What about flex plate and flywheel?
Is it flexplate enough for LS3, or better to change it with flywheel?

plavutka

Hello,

Is it neceseary to change pistons or other engine parts to crate engine LS376-480 marinisation or can we just keep originall parts?

hallj

Switch to a flywheel.
the pistons should be fine. Run the coolant at a minimum of 160 degrees F.
Do not apply full load until the engine is warmed up.
