crmax

mine didnt come with the cover the forgot at the factory to put it on, I like it off anyhow. I got mine from rexmarine

crmax

and Ive seen the k&n on with the cover so yes it should fit back on

Well, including uncoverring the boat, opening the hatch, pulling the over off, swapping the flame arrestor, reinstalling the cover, closing the hatch, and covering the boat... it took about 10 minutes.

Much easier than I anticipated.

Thanks for the input.

I also have a 7.4 MPI in my boat did any of you guys notice or see (on gps) any performance increase???

dloftis

pstorti,

I haven't tried yet... although I'm at the limiter with the stock filter. I'm changing to a 24p Bravo I from a 23p Mirage Plus this weekend... So I won't REALLY know. But just by looking at the thing, the engine is going to breath easier.

Oh yea the gasket behind the throttle body protrudes into the port I trimmed that out to. Performance gains unknown at this time because I havent gotten a prop on it yet that dosent smack the rpm limiter but midrange cruse seems better

crmax

I put the k&n on at the same time I put the thru hull exhaust on my mph went from 58 to 61.5 both were gps readings

Which engine do you have. They gave me a different P/N

dloftis

Rick,

I've got a Mercruiser 7.4MPI 2001 (same as 2000)

Check this web site out:
http://www.knfilters.com/marine/boats.htm
It lists most Mercruiser motors and the appropriate part number.

(BTW: The 59-5004 is correct for my engine... it fit perfectly.)

dloftis,

The 59-5004 looks by numbers like it's higher (taller) than the stock arrestor. It shows 6" and although mine's down at Travis from memory that's taller than stock. Did you find that to be the case or is 6" about right?
