Who labbed it Gary?

Re: Superbabi !! Heres your pics of your Y2K
 

Tom, this was done by Merc. Racing Props. I will send the 5 blade 27" maximus back to Merc. Racing for a little tweaking. She needs 100-125 RPM'S more to the Rev limiter.

Re: Superbabi !! Heres your pics of your Y2K
 

how much is she truning right now and where the rev limiter

Re: Superbabi !! Heres your pics of your Y2K
 

4 blade is at 5240 rpm's. The 5 blade is at 5150. The limiter is at 5275-5300.

Re: Superbabi !! Heres your pics of your Y2K
 

hmmmmm... You could push that motor to 5500. 502 right?

Re: Superbabi !! Heres your pics of your Y2K
 

Not sure ??

Re: Superbabi !! Heres your pics of your Y2K
 

I dont think the rev limiter from merc is adjustable... You would have to reprogram the computer to bump it up.

Hi Gary,

Mercury topically sets the rev limiter 150 to 200rpm higher than the maximum recommended rpm for a given engine.
The max recommended rpm for your engine is 5200rpm correct? Likely the rev limiter is set at 5350rpm... :cool:

Yes, the components used to build the 600 would likely work without failure to 5500-5600rpm. It is a bit more complicated than just changing the rev limiter in the computer though. The fuel mapping would also need to be changed to allow for the proper mixture at high rpm or the engine would run lean.
Another thing to consider are the valve-train components used. Even if you did spin the engine faster, would it actually make more power? Probably not, because the cam shaft used was likely designed to make peek HP at around 5200rpm in this 502 cube engine... :cool:

I maintain that the best way to get more HP out of your 600 is to turn up the boost... :D

From speaking with different prop gurus, I would say prop your boat to reach 5200-5300rpm with a vary light load. And I would define a vary light load as 1 person and 10 gal. of gas... :drink:
