There are cracks appearing in the fibreglass around the base of the engine where it bolts to jet drive.The cracks are running down the center of the flange and down both sides. Reccomendations and probable cause.
Have a 2004 Speedster 160 with Merc 240 EFI, have been searching info on a Dyna Boost, has anyone had any experiences with this stuff. Can it harm the engine and does it do what the adds say.
