MercRacing 565.
 

Cult

It seems as though I've found small home here on the AT forum, I feel as though I fit best with this clique of human beings. I've friended some on Facebook (Pete, Scott), even one on LinkedIn (Scott, great professional networking website). With all of the new marine technology coming out in recent months I find myself wondeing what everyone thinks about the new 565 BB from Mercury Racing? Has any tested it out? Any positive or negative results? Regardless, I appreciate how open and welcoming this board has been, some aren't as much to youngsters like myself, thanks'.

There have been a few threads on them in the General Discussion. BLee has them in his new 2012 90+mph Top Gun. "Some" of them were "recalled" early in the summer. There's a thread about it.

Our Merc reps/friends have been singing their praises, and we like that. I anticipate seeing some 565 action in an AT hull in the near future.

There have been some impressive results with that engine in the 29 OL and 24 Nordic cat. Not the prettiest engine, but it seems to be a stout performer.

With the proven track record the 525 has I see no reason this motor will be anything short of awesome

After seeing a few in person now (29 OL, 400SS Formula) I don't hate the look of them as much as I did in pics when they first debuted.

I dont think ther bad looking and you can choose from 11 colors, as for the 565hp that is about the same as the 525 as they are in the 560 hp range.

More HP and torque like a 600. Direct conversation with Kevin Skiba at Hi-perf and Brad Halpin my local rep. I'm putting them in a new 37 so will know everything there is soon. One thing however, DTS or fly by wire only. No more hard shifts or unsynced engines! (so I am told)

Turn the key and go!

Way to let the cat out of the bag! Work with me Bro! :D. :drink:

Ahhhh if I only had a nickle...........:grinser010:

Im sure it will be a good package but the power isnt what you think it is.... The 525 is 502 cubic inches. The 565 is 532 cubic inches. The power per cubic inch is the same. Do the math. So they didnt do anything to make it more efficient. Same manifold, they blocked the front and put 2 throttle bodies on top. It has the new ecu the 1100/1350 has. So of course no one can get into it. The electronic shift and drive by wire is nice. Until you need to buy parts. Again it is a nice step up without a blower but they could have done more.

560 on a hot rod dyno. Realistic is 540. So my guess is the 565 will make prob 580. Good power without a blower for sure. Only a small improvement in power per cube. The blue engines always make at least what they advertise and usually more.

Souds like a sweet set up if the price is comprable to the 525 package.

It looks like they increased the stoke by .25 inch. To bring it up to 533 CID. Keep in mind you have to run 89 min fuel in the 565 as opposed to reg 87 in the 525. I figure they bumped the timing up on the 565 because the compression is actually .05 less than the 8.75 that's on the 525. I know there are 525's out there that are in the 600 bracket depending on what has been done. I like the idea of being able to run reg 87 but 89 seems to be easier to find on the water than 91+.

Im sure the price is alot higher. Merc never goes backwards. On the merc blog Fred Keikhafer did say they are a little disappointed with the sales numbers but thats because of the weak economy in the market that engine is intended for. The 1100/1350 is selling like hot cakes. That engine is the most impressive thing they have ever produced.

The 565 or the 1350 is the most impressive thing they have ever produced?

The 1350. Im not real impressed with the 565.

Why not?

Because all they really did was make the engine bigger for more power. 580-600 is very easy to obtain reliably out of 502 cubic inches. A few cylinder head and manifold changes and a 525 makes 600 on 87 octane. I did it. On 240 hour short blocks. With that said im sure the electronic drive by wire and shifting is going to be awesome. Sync will be nice. Hope the throttle response is as good as a 525. Let us know.

They also turn the 565 up 200 rpm over the 525. It should be a great package. But you you really can't compare it to a quad cam twin turbo 1100/1350,To totally different beasts $$$$. The electronic shifting and sync should be very nice. Doug

pm sent.

Oh yeah... no comparison. The quad cam is a veey cutting edge package. From some internal pics and stuff they utilize Latest race technology. Thats why it surprises me they wouldnt have made some more improvements the the n/a big block.

A 37 with a pair of 1100's.... hmmm! :eekdrop:

At that point...why stop at 1100's???

A 37 with a pair of 1350's!!!!

I like the way you think...

Has anyone put 6's on the back of a 37? I don't think the XR's or BMAX's will handle 1350 a side........

http://www.boats.com/blog/wp-content...-565-model.jpg

man, tough crowd... I thought they looked sweet, and honestly I'd LOVE to have a pair in my boat

Would realy like to see the 42 with 1350's and Arnesons. Now that would be a sight to see running.

probably because it would cut into their supercharged engine sales..
Even N/A a quad cam big cube engine would make 650-700hp easily..

The 37 Outlaw race boat had 6's I believe. the 1350's need the M8 drive.

Sure, that is easy to do to a 525.....now warranty it for the guy that will get in his boat and hold it wide open for an hours at a time :D There are many that are not mechanincally inclined, that buy these boats and run them hard. Increasing cubes and air flow was the safe way to get more power out of this platform, and it probably still soots the transom...which is safe :lolhit:

Say what you will, but I still believe that there are smarter guys at merc than some give credit too.

I think they have a whole team of smart people... my stuff is basically stock with better heads and manifold. Stock comp, timing, cam etc. Nothing on kill. I can leave it wot all day. The stock 525 is rich until wot full load then a bit lean with mercs stock tune.

I just think they could have done better with a BBC based na engine. But I'm not so sure the market is there in this economy.

That would prob make a great replacement for the 700. Probably last forever too!

I will verify but I believe Merc is building the 502 block themselves.

After Obama bailed out GM I think all we coulda got from them is welfare motors. :party-smiley-004:

The 565 leaves a lot to be desired in the looks department, but I believe the engine cover is a blank canvas to make the motors match the boat's paint and graphics.

hint hint!! :drink:

GM performance is still going strong with lots of 502 block crate engines avail. Blocks will be available forever. Pretty sure 565 is the same just 4.250 stroke. 454 bore (4.250) blocks are gone... hence no 496 anymore. I'm sure the EPA and treehuggers and Obama will figure out how to squash this stuff eventually. Our boats will be required to get 54.6 MPG. Lol

:stupid::lolhit::whistle::party-smiley-004:

At least a good portion of that was paid back... How much did we get back from wallstreet? ... And they got 10 times more! :)

They will never pay it back... and the raping continues!

Totally agree. Everybody that has walked in and has seen them has been in total awe!

People just hate change. Well, maybe the 1600 Penns. Ave address excluded.....

Easy now Reverend! We don't want this moved to the politics forum! :hijack:
