Thanks everyone for the great feedback (see topic on repower options).<br /><br />For me the remaining question is did OMC/Johnson make a better engine in 1991 or 1997? The guy who will sell me either a just rebuilt 1991 150 HP for $3,500 or a just rebuilt 1997 175 HP for $4,500 feels that the 1991 engine is more solid & a better deal.<br /><br />He will sell me either engine. His gripe about the late 1990's Johnson's are 1) their fuel & oil injection both stink (he will not warrantte VRO [he wants me to manuualy premix) and 2) Johnson started making engines that would break down after 6 or 7 years so that the user would have to buy a new engine. In fact, he says that the 1997 engine that i am interested in blew its powerhead because the VRO stopped working properly.<br /><br />What's your opinion?
