Whippling a 520-540-565?

[Gasnsuntanlotion]

Has anyone done this? I Don’t see kits yet on Whipples site. Engine models too new?

You can turn a 520 into a 565 with just a few minor tweaks and $$.

Not sure I would do anything until the warranty is up.

I have a 520 and looked into doing a whipple a couple years ago. There wasn’t a system out there yet so I talked to the guys at Teague about using my boat to develop the system but it just wasn’t worth it. If whipple broke the motor on the Dino figuring it out they would have payed to fix it but if they just hurt it and we found out after I was screwed and on my own. They would have only discounted the system too. Plus all the money for de-rigging and rigging. Figured I’d let someone else take the risk. 3 years later and there is still nothing.

They don't have anything out yet. As Singleton posted. A 520 with E tops or Big tubes will make another 25-50hp. Plus a tune it will make 565.

Same with the 540. It will make 565 with a tune. 565 should make 585 with a tune. Main thing is extending the usable rpm range to swing another pitch.

I figured as much but the 500-525efi have had a whipple kit out for quite some time now. Guess these new 520-565 are too new and whipple doesn’t see a demand yet? Plus all the new high horse power outboards now probably takes a big bite out of the N/A engine sales.

I think it might have something to do with the newer electronics and digital throttle and shift maybe too?

I think you’re thinking 520 to 540. A 565 is completely different bore and stroke, as well as dress, harness, and dual computers.

This.

What is the uplift from a 520 to 600 at purchase? That might be a contributing factor..

And how would you know this?

You talk like you work for Mercury

 

[Ziggy]

Yup, headers and a reflash on the 520 and you'll be in the 540-550hp range.

Merc 520 vs Merc 600, about 15K.

That makes sense. I knew you could do one, but was not 100% sure which one of could jump up to.

So let me ask this. When you look into putting a whipple or turbo on a merc motor.

Does it not make more sense to sell the engine just before the warranty expires and have Teague, Boost, Brummett or anyone else build you a motor.

Either way you’re out of a warranty. Seems like the only reason to keep a Merc motor is to keep it stock for warranty and resale.

I like outboards so I’m Merc all the way lol

All of that info is on the Mercury Racing site though.

And a Whipple is over $11k plus install it seems.

So adding it up front by getting a 600with warranty seems like an easy decision.

Teague mentioned on his last Teague Talk that it wasn't economical for him to develop a program for the 520-565 line as their wasn't enough of them in circulation yet. I assume other builders are the same way assuming you don't want to pay for the R&D.

I agree. Plus later down the road with all the Whipple kits for the Merc 600 you can have around 900HP

But the “Mercury Racing 565” is just soda king gorgeous. I honestly find that the sexiest motor I’ve ever seen.
