Does anyone know what the torque setting is supposed to be on the four riser bolts that mount the exhaust riser onto the exhaust manifold? I can't find it anywhere. I know it isn't a lot, but no idea (maybe 20-25ftlb?)? Thanks, Gordon GT40 ------------- Gordon '97 Ski Nautique, GT40 |

If you lube the bolt with Never Seize (or equivalent) you may want to back-off the torque by 25%. JQ ------------- Current 2003 Ski Nautique 206 Limited Previous 2001 Ski Nautique Open Bow 1994 Ski Nautique Open Bow Aqua skiing, ergo sum |

Thanks everyone. I replaced the heads a number of years ago, but I couldn't find the torque info. I used anti-sieze last time and they came out with no problem. Will do the same with these settings. Thanks, Gordon ------------- Gordon '97 Ski Nautique, GT40 |
