It seems like Mercury Racing has covered all the bases in the performance engines dept with the 525, 600, 700, 850 and 1075 lineup. What is your favorite and why? I like the 850 SCI engine...it's pretty sweet. I cannot afford it, but I really like it. That would be my personal choice.

I also wanted to point out that I find it unusual that alot of people would stay away from blower motors for reliability reasons, yet 4 out of 5 Merc engines have blowers.

What ???

No Outboards?

That should be another thread entirely......2 different animals

Just kiddin' with ya!

300xs

525s would suit me just fine in something like a 33' Powerplay. Good enough to get you just above 80, naturally aspirated and reliable power that won't blow a drive.

i like the big 3.0L TKS, great on gas, easy to winterize, ussualy a ton af room left in the engine bay to get in there and work on your mills....even in twin applications

Never owned any of them. But I beat the poop outta my trusty 502 's

Isn't "Mercury" outboards and I/o's and inboards "MerCruiser"?
I thought this was going to be an outboard poll by the title.

Anyway, I picked the 525's for reliability, cost and the fresh-water cooling.

Any Opti-Max outboard would be my choice of O/B's.

I like my 525 efi's.
