I have a K&B 7.5 9100 df engine, New in Box, that I am modifying for marine use. I have alreary purchased the marine head from MECOA.
I was told the Square connecting rod, in these old engines, was too soft. I have the new Tubular Rod to install in it.
Question; The tubular rod is smaller (less mass) than the original square rod. Can this rod be used without rebalancing the engine? Also, is this new rod actually stronger than the larger squared rod?
Thanks for the info.
