The centerline of each bank of cylinders will be 90 degrees from eack other.<br /><br />All 200's are 90 degree blocks. Crossflow, loopers, small bore or big bore. Yours is a big bore, 3.0 liter, open deck, 90 degree, non-finger ported looper V6.<br /><br />See how simple this is?
Oops! Left out the 3.3 liter DI 200's. They're 90 degree blocks too.<br /><br />Oh -- Don, yours should be an Evinrude XP (same as a Johnson GT). Really great motor!
timely subject,<br /><br />The guy at Napa asked me the same when trying to order thermostats for my '85 90HP V4, I said "huh?"<br />Is mine a 60 or 90 deg.?<br />H90
H90, to be blunt -- if your parts guy asked you that, you might need a new parts guy. <br /><br />Seriously, you have a 90 degree crossflow. 3.500" std bore. All crossflows are 90 degree blocks. <br /><br />Hope that helps! Good luck!
