525 vs. 496 HO--supercharged
 

Which way is better? Seems like I could do a 496 SC for less and go as fast as the 525. But if i ever whippled the 525, that'd be a fast boat.

Re: 525 vs. 496 HO--supercharged
 

If you have the extra $$ to go for a Merc 525 up front your boat will go 7-8mph faster and hold it's value better.
I would not Supercharge a stock 496HO; it has cast pistons that will melt from the added heat.
I would suggest powering with a 496HO. When the warranty period is up go for a 496 HO to 525HP upgrade kit from Raylor or Tyler Crockett.

Todd, if you can pull off the 525 money wise thats the way to go, best all around motor, every sportboat company uses them.

Re: 525 vs. 496 HO--supercharged
 

Is the difference in price $!5 fromt the 496 to 525?

Re: 525 vs. 496 HO--supercharged
 

Sticker price ( list ) 496 HO With/XR $$ 32K......525 XR $$ 47K.......Those are list prices, no one pays that.

Re: 525 vs. 496 HO--supercharged
 

How much would that cost??

Re: 525 vs. 496 HO--supercharged
 

It all depends Todd. If you do a merin or dart block opposed to chevy, TBS vs. Whip AFR vs. Canfield it all depends.

Re: 525 vs. 496 HO--supercharged

Re: 525 vs. 496 HO--supercharged

Re: 525 vs. 496 HO--supercharged
 

Don't fool around with any Merc Stuff. Listen to Lightspeed and Pure Energy and build a JC Performance Mill for what ever boat you decide on THolland.....

Pat,
I heard the new 496HO's come with Forged pistons. Am I wrong???

Re: 525 vs. 496 HO--supercharged
 

Hi Rick,
Sorry, but yes you are wrong. All the GM 496cube/8.1L engines come through stock with cast pistons, even the 525HP HP3.
There are aftermarket kits with forged pistons available now though.

Re: 525 vs. 496 HO--supercharged
 

It's my understanding that some of the very first 496 HOs came with forged internals.

Re: 525 vs. 496 HO--supercharged
 

Crank yes pistons no...

Re: 525 vs. 496 HO--supercharged
 

I thought the NEW 496 HO's have forged pistons. As opposed to the old ones. A 496HO whippled does 81 out of the box !!!

Re: 525 vs. 496 HO--supercharged
 

All you need to know about the new GM 496cube marine engines...
