I've senn both in jet boats, what's the advatanges of a flywheel and advantages of a flexplate in jet boats? Thanks!
Either will work ... it'll just change you drive shaft length or motor placementif you change from one to the other due to the thickness difference ...
a flexplate will RPM the motor faster due to less weight on the reciporcating assy ... but a flywheel gives a more accurate balance (so I've been told) ...
Again, this is what I have been told ... I have seen data to prove the RPM difference ... but no data on the balance issue ...
