my friend just bought a new g3 flat bottom boat with a 90/65 yamaha jet drive outboard. well we broke it in like we were told to then we headed for shallow waters. the motor performed great but we ended up smacking the intake grate and housing on a rock going through rapids. does anyone know if there is a stronger aftermarket intake grate and housing avaliable? it would be nice to have something alittle more durable than aluminum.
