I had a Micro Burst hull about 17 years ago and it had some of the most violent blow overs I’ve ever seen. It would be going like a demon on the straight away when all of a sudden it would lift off, turn right side up and go back into the water backwards and bend the trim plates back under the boat.
There have been a few different versions of the microburst over the years. The really early ones did run very loose but the later ones run great.
From what Archie has told me for gas, the 47 is good for 260's but really not great for big blocks. That's why Dave came out with the 51 and it runs very well. I'm not entirely sure about nitro though.
