Marinized ready to roll exhaust and everything new from scratch 20-25K.
Be careful using an engine built for cars, cars dont have water reversion problems or issues with high idling.
A high idle in a boat with an outdrive = broken drive gears and blown clutches.
In a car you can run as much lift and duration as youd like to make X number appear on a dyno.
I have a a really nice 406 and if I had to do it all over again Id have just gone with an FI big block and been done with it.

Pricing out a 500-550 small block after the miami show. Have to get a feel for where the market is at. Anyone price one out or have a feel for what they would pay?
Not sure if stroker is the way to go and probably shy away from LS for now but who knows. Carb and efi options for sure as well as all quality parts.

Ive watched a lot of guys try to slip in crate engines designed for cars and have trouble.
Notice bill mitchell who makes great products voids the warranty for marine use.....

Well by now all you guys have heard about the 557 H.P. supercharged small block chevy in an outboard .. Wonder how long it will take someone to put an outdrive like Ilmor, Volvo, or Konrad on the back end of that engine and give Merc a run for their money ?????? And not cost $204,000.00 an engine or some other out of this world price!!!!!!! Sounds like a great weight to horsepower ratio !!
Hows that for a large crap ball that just got rolled ..

It's a V8 Supercharged built by Seven Marine
Here is a Facebook Link to Hering working with them on Props

It is state of the art Outboard not some standard small block chevy....
If I knew how to copy and paste pictures on this site I would post a few but apparently I am too tired to figure it out. The Insert Image only offers "whats you pictrues URL". I thought there was a paper clip at one time?
Anyway, Here is the companies web site.

I guess they are unveiling it at the Miami boat show.

yeesh- pretty sure thats about what my Ilmor & XR combo weighs.
This is no doubt a cool dealio...and not at all what I thought the poster was talking about (homebrew)
Its really nice to recover the room in the boat an I/O takes up - but thats a lot of weight and pressure on the transom, plus I have to wonder how that gearcase will last.
