Caught up in the moment, I purchased a boat without doing the proper research.<br /><br />The boat was sold to me as having a 200hp Mercury outboard motor on the back. I'm pretty confident that it's really more along the lines of an 1984 with 150hp.<br /><br />1. Are there any obvious cosmetica differences between a boat built before 1996 and after? When did Mercury change the engine cover or graphics?<br /><br />2. I've found a serial number tag on the transom:<br />6552325. I'm not certain that this is the correct one, but it appears to be. I believe it's a model 1150724, but I'm not sure. When looking for parts, that model looked to be the same.<br /><br />Any help would be appreciated differentiating these engines, and finding out the identity of the one on my boat. Thank you in advance....
