1. Please do not reply to old topics or hijack existing topics. Old topics of a technical nature are like a library book, Please do not write in them.

2. Old topics should be considered archives and used for reference only. Please do not reply to them.

3. Do not take over someone elseís topic (aka hijack) with your own question, even if it is similar. If you have a question that has not been covered to your satisfaction in the archives, it is always best to start a new topic of your own.

4. If you have a question for the original poster (OP) and the topic is over 30 days old, send the OP a PM, he may not even visit the forums any longer, or may not notice your question in the old topic.

5. By starting your own topic, you will receive the maximum number of views by forum helpers that may not even notice your question when itís posted at the end of someone elseís topic. And those answers will be specific to your particular issue.

6. Please do not post to topics that have been inactive for more than 3 months unless you are the original poster. We have very active forums and any topic that remains inactive for that long should be considered "dead". It is especially confusing when there is an entirely new question posted to an old topic.

7. Posting at the end of any topic is considered to be hijacking the original posters topic which in turn subjects the topic to be closed if it continues to happen thus not making it fair to the original poster in the future had for some reason he/she needed to return for additional information or provide an update of the problem solved which is always welcomed within a reasonable amount of time frame.

8. Please note that you should see a red banner pop up near the bottom of each inactive topic asking you not to reply to old topics. The Red banner will read: Please note this topic has been inactive for 90 days. For the best results, please start a new topic.

Thank you all in advance for doing your part in helping iboats run a smooth ship.

  • 1987 Evinrude XP150

    I have just purchased a boat with a 1987 Evinrude 150 XP Model#E150STLCUR. The main part of the motor and hood are Dark Evinrude blue with the following exceptions. The top of the hood is light Evinrude blue and the lower unit is light Evinrude blue. Is the correct for this year? I have seen a few other 150XP's and the lower unit is dark Evinrude blue. Would it be correct to assume that the lower unit has been changed or swapped out? Did the XP models have a different lower unit than standard 150's? Was the gearing the same? Was the XP lower unit more aerodynamic? Just curious, any input would be greatly appreciate.

    Never know about the paint, or even if a lower unit has been replaced...CU is 1987 though..

      The XP/GT's had the same gearcase as the standard models. There was a year that the gearcases were polished by Last Chance....er....I mean Second Effort.

        Thanks for the response. While I have your attention. Would you be able to tell me what differences if any are the between and XP or GT 150 and the standard 150? Also what's the pros and cons crossflow versus loop charged.

          The difference between the crossflow XP/GT and the standard 150 is mainly cosmetic. There are some performance differnces. Some 150 XP/GT's had 200 port timing, or real close to it. The heads are different and have really good chambers.Dont even try to compare a crossflow to a looper. The looper makes more torque, stock, than a modified crossflow ever will. As a crossflow the 150 XP is a real decent motor but its not a looper.

            Thanks for the response again. Just curious as to why OMC left the 150 and 175 of that era as crossflows and the larger 200+ engines went to loopers. I previously had a 1986 120hp looper. I was aware of this crossflow/looper thing until I purchased the 1987 XP150. I was suprised to see that the 88's, 90's 110's 112's and 115's were crossflows and the 120 and 140 were loopers.

              In 1991 they brought out the 150 / 175 loopers and the 150 / 175 cfs were discontinued as of 92.

                Dhadley, would you be able to tell me in a nut shell the difference between a cross flow engine and a looper? I know that I have a cross flow now and I used to have a looper, I'm just curious as to how they differ. Did the 150's and 175's change to loopers when the 60 degree power head come out? Do you know why the 150 and 175 were the last V6's to go looper? I thank you in advance for consideration of my questions.

                  OMC came out with their big loopers in '85 as a 120/140 V-4 and a 275/300 V-8. They shared the same bore/stroke just had more or less cyl. The cross-charged 150/185/235 remained, In '86 the V-6 version of the looped-charged V-4/V-8's were intoduced. The 150 (149 CID) and the 175 (160 CID) cross-charged engine remained. The V-6 loopers were to heavy for the 150/175 ratings and the V-4 would be pushed to acheive the ratings. OMC new they need an engine (looper) that would fit in this range so the 60 degree loopers were introduced in the early 90's the later to cyl were loped off and a new loop charged 90/115 V-4 were made using the block geometry of the 150/175.
                  Show me a good loser and I'll show you a loser.
