Hi I am new to the fourm but so far I am in love this site is great one of the best I have seen. I just bought a 89 sun sport and I need any info on ideas for installing a ballast system. I have a long sack in the ski locker in the back and thought about fly high custom makeing one fot the front under the play pen seats but there is a wall between the two. Also haveing a slight cutting in and out while under a load. i have owned may boats so I have done all the normal stuff. But rebuild the carb and replace the distributor I and wondering if the spring and magnets might be the prob also its runnig a 160 thurmostat I think it needs a 140. Thanks Chris
