Can anyone give me any insight into this particular motor reported to be a Nissan 90 hp. All I have to go on is model NS90A, serial 3B7-1 11147. Anything I should look at in particular and has this been reported to be a good dependable motor. The one I'm looking at hasn't run in 3 years, has good even compression, good spark and appears to have been well taken care of.<br /><br />Thanks,<br /><br />Mike
