RE: Thunder Cat 31
I am were you are at with my Miss Vegas; got a bigger prop and it aint running like it did with the stock prop. I am going to try a higher nitro fuel (50% vs. 30%)to see if that helps any combined with adjusting my strut. Cooler weather is also causing my boat to run poorly so I am going to have to adjust the engine as well including going with a colder plug. Plan on doing all this tommorow so stay tuned.
