Hello. I have a johnson seahorse v4 90hp that has been sitting since '98. I bought this boat from a neighbor who inherited it from a sister. Nobody knows much about it except that the neighbor says it was running at the time it stopped being used.<br />What should I do prior to firing the motor for the first time. It has been run in salt water. It appears clean and the flywheel turns fairly easily by hand except for the compression stroke.<br />Also, I cannot find the year of this motor. The best I can make out the model number is 090TL0NB. I went to a site http://www.marineengine.com/manuals/johnson/index.html# that breaks down the code but I still cannot get the search block to accept my number as a recognized code. Based on the info I found it could be C90TLCNB but this will not work either. The boat is an '82 Custom Craft 18'-19', open bow with walk through. (if anyone can point me to info about this I would appreciate it also)<br />I was told the motor was replaced, but maybe it was just rebuilt?<br />Thanks for any help!<br />Jeff
