Billet alum flywheels

[DS77]

Thanks for the quick turn around Jeff can't wait to put my hands on it. Peace steve

[Freddie Webb]

Jeff awesome work! I'm glad the flywheel was clean enough. I will look and see if I have another one that clean. You have me interested in the Omc flywheel!

[PaulR]

Jeff you might want to fabracate up the alum plate that the pro max use;s on your cnc and sell them with the 40 amp flywheel at a small charge so people have what they need for the retrofit, Maybe even stock the stators and regulators and sell as a package to the guys that need everything for the change over just a idea but the alum plate to mount the regulators is something you can machine in mas for little exspense and make it easy for the guys that are buying your flywheel just my 2 cents. DEz nuts

This is a great idea! I would really like to see pics of this done on a 260 or Drag!!

[jeff dunn]

Will be working on plate for regulators soon. Jeff

Jeff, don't know how I missed this thread, stuff looks great, I will contact you directly to talk more on this ( as I am looking for the 40 Amp )
good luck with all of this, you should get very busy once folks catch on to this.....

[outboards4life]

definitely interested in one for an omc, can't wait to see one if they turned out this nice for a merc.

What does the stock 260 flywheel weigh?

[fasterbass]

Also as a note.if you need a regulator Cdi makes a kit that bolts to the top of a 260 at the very back and if you get a lighter race type flywheel and go down from 40 to 16 or 9 amps you have to go to a smaller stator which isn't a large amount of money and to me it makes a noticeable difference.Nextissue u need to know about. These flywheels that are cut down really rum good and a must for a winning motor but all the ones I have drove vibrate a lot.MYSELF I prefer a stock merc racing flywheel on the stator and trigger motors .mind you that is my personal prefeencce.

[jeff dunn]

Stock flywheel is about 7lbs.

Lee these are new ,machined from billet alum,I use merc hub and merc starter ring then they are balanced.
40 amp is 7 lbs
16 amp is 5 lbs

[fasterbass]

Dropping two pounds is a lot.some engine shops brag about dropping over 600 grams

[wildwiley]

got my 40 amp and it looks great and weighs in 4.4 ounces under 7 pounds ! BIG THANKS jeff

[stoker2001]

Please educate me,i tryed to google,and didnt find much?
Tell me about all the pros and cons of a flexplate (steell) Vs solid billet (alum) on a drag 2.5 moto
thanks

[jeff dunn]

There shouldnt be a problem on the 40 amp, due to the stock fly wheel is around a 1/2 thick on the top and does not flex any way. Merc has not made a flex fly wheel since the early 90s on any of its motors. The only flex one is the race flywheels, the alum will flex more than the steel on the 40 amp and should be fine. Plus its half the weight of stock. Wild wiley said his is under 7 lbs in his post above.

Now as for the 16 amp if there are any one who wants one built with a flex plate for rpm over 10,000 I can build one with flex plate. I have tested rpm up to 8500 on 16 amp with out flex plate and didnt see any problems. I will be building one in the next week with a flex plate , and hope to have pics up soon. All fly wheels that I build will be balanced before leaving.

The reason I started building these flywheels was to stop the broken , and loose magnet problem. The end result was 2 flywheels that came out lighter than the oem , if any one has any questions please give me a call 843 222 9498, or pm me.

Also the less weight spinning around the top of the crank will greatly reduce the stress and wear on the upper crank bearing.
