    don't do it

    agree with lucky and hallett I run a big heavy flywheel and the large ATI dampner , don't think it matters what drive your runnin , boat engines are under heavy load and when held at a constant rpm or are unloaded they will develop damaging haromics if you don,t run the heavy stuff . your starter will last better too, especially with a big hi-compression engine .

    I think a good question is "What appilcation - jet, v drive, I/O and what engine size are we talking about ?"

    If I/O, what kind of drive ?

    Not to mention a flexplate was designed to be bolted to a torque converter to stiffen it during cranking. Some people never have a prob. some get the horrible grind!

    Some people say that a flywheels help to absorb harmonics.

    I run a flywhel and torque coupler

    My thoughts on the heavier flywheel in pleasure boat ! when you launch off the rollers you will not build rpm as quick and when you re enter you still have centrifucal force on your side . I believe this combo will help longivity of parts along with harmonics ! JUST MY THOUGHTS - and as you may or maynot have noticed I am nobody

    Why not just go with flexplates, or are you still double-clutching it?

    No reason not to change it other than possible driveline differences you may get into.

    I can't think of 1 really good reason to run a flywheel unless you actually DO install a clutch assy in the boat, and why you would do THAT is beyond me.

    15 or 30lbs?

    Hi Guys

    I found performance boats mag in with my shipment from CPPerformance and so here I am. :-)

    So I wanna take off my 30lb flywheels on my bbc's and fit the 15lb ones.

    Starters are on there way out any way so I can overcome that issue and justify the cost too!

    Any big reasons why I shouldnt do this?

    Steve
