The cracking you are finding is really minor BS, the older ones developed some minor cracking over a period of many years almost all of which was outboard not where the new ones do. The early newer ones with the stringers placed outboard of the strakes cracked very early in life, but Donzi came up with a good fix and have strengthened the new ones. The older 22's had the stringers set at 22" on center and placed directly above the strakes which gave them support where it was needed, the newer spread stringer setups left the strakes unsupported which caused the cracking issue. It has also been pointed out by a few owners and other knowledgeable guys that the lowering of the 496 engine packages made the boats porpoise due to the extra drive leverage, we got a first hand look at just how bad one could be at the 06 1K run. Atomictan "Carl's" boat would literally hop drove him crazy! The bottom fix works great, add a shorty and you are in business!
