40 amp flywheel

[985Coonass]

Did mercury make a light weight 40 amp (red) flywheel for a 2000 model 225 promax?

U mite b abke to get it cut on but I really doubt it. Not really sure but no lite weights stock. This is also comin from someone that's never ran a 40. I always say do away with it unless GOTTA have it

first coupla year of 40's were red and a "flex plate" type.. justa tad lighter but not enough ta mater much.... nothin' else by merc.

Never seen a PM come with a red flywheel especially a 2000. They were black cast iron.
Red flywheels with bigger magnets like the black cast iron were in 80's 40amp system if I remember correctly.
Like mentioned above they were not much lighter and only small advantage was the flex plate. What I also found a down side was the cooling, not enough holes for venting to properly cool with higher rpms.
Also as mentioned J Dunn did make some but had issues not sure he is still making them.
Brendan Powers was making some real nice ones, not sure he got them completed, he was close and testing. Have not spoken to him lately.
These 2 below I swapped out I while ago.

LOL yes you have! Unfortunately one flywheel did not play well, lost a magnet since it was cleaned too well with lacquer thinner....

I personally have no problem running those red 40amp flywheels even though the weight savings is not huge every little bit helps that upper bearing and crank.

I have found duplicating the 245/260 16amp setup as was design has worked very well for me.

I had just got rid of a red one few days ago and it was heavy, cant imagine the black one being much heavier, dnt believe u would ever know the difference.

[tux974]

It was not much but yes a bit. Mercury just did not expect/recommend to spin them above 7000 like many of us do to the 225Promax.
If that cast iron is out of balance in anyway it really hurts the upper crank bearing longevity.
