Hello all, I'm considering buying a trophy with a 04 150hp optimax. I asked to guy to start the motor w/water muffs. He ran it for about 1 minute and I didn't notice any blue smoke. I'm a newbie when it comes to outboards so my question is this normal? I expected to see some smoke being a two stroke. Or is this engine that efficent that it smokes very, very little? BTW, he started it at somewhat higher rpm then tapered it down after 10 seconds and never really reved it. Thank's
