I am hopeful some of you may have info regarding the engine in this 2410B. It has a C157 gas engine with a severely cracked block, and I wish to exchange it with something. I am having a tough time finding this block. Is there another engine that would interchange? Am I crazy thinking a C152 from an H would be possible? It seems the horsepower rating of this 2410 is greater than anything an H could muster. Any suggestions would be helpful. I would even consider the C175 which is diesel, but not sure what might be entailed for changeover other than fuel. FYI engine number stamped in block 157CT2U007882 star Thanks so much, john
