Hi! New here so thanks in advance for any info! I have a 1998 230 bowrider, bought last fall. Seller said it ran good over the summer. I did some referb on the interior, new manifolds and risers, tune up with NGK BPR6EFS plugs, wires, cap and rotor. Oil change, fresh gas. Started in the driveway with muffs, idles fine, throttle up and down ok. I'm Took it out for the first time, idled out ok but when I accelerate, it is gutless, takes forever to plane, it will run at 2000 rpm but will backfire through the throttle body when I try to give it more throttle. Any ideas??
thank you!
