i have aquired an outboard and would like to know the year and name of it so i can aquire a manual for it. The only number i can see are 32900-93300 and 070000-0331, these are on a component but i am unsure as to there relevance where should i look for the number if this isn't it?<br /><br />Also how do i tell if its four or two stroke the only difference to me is what fuel to put in it. Its a suzuki 50 hp thata as much as i know, thanks for your time leeips.
