My optispark has gone out on my 97 formula I am wondering if it is worth going to and aftermarket one like a Dynaspark or just stick with a stock one? any pros or cons on the dynaspark. and no im not looking into putting on coils until i build my 383.

thanks

 

If you got the cash go for it, other wise a new stock unit will do just fine. Do your self a favor and replace the complete unit, not just cap and rotor

 

If you get a stock replacement you might wanna take the cap off and make sure the screws in the rotor are tight. I've heard of several of them being loose and it will fly apart on you and that means pulling it off the motor again. I'd put loctite on the screws.
