Tohatsu 3.5hp Four Stroke Review

I bought that Nissan 3.5hp four stroke [ same like tohatsu/mariner 3.5hp ] in May 2006 , after 4 weekends [ about 20 hours of use ] part of the engine cowl/cover broke off,I was waiting 4 weeks for the new part. After 40 hours of use [ about 8 weekends ] upper part of engine cover broke off and at the same time I noticed that the engine oil was leaking [cracked engine block !!!] After 2 months of negotiation with Nissan-Tohatsu dealer and many phone calls to Nissan/Mariner/Tohatsu Marine head office in Texas, they [dealer] replaced that engine block and engine cowl/cover, I sold that piece of @%$@*& immediately after that. DO NOT buy this motor !!!!
