Help Tip: If you have a question that has not been answered to your satisfaction in the archives, it is always best to start a new thread of your own. By starting your own thread, you will receive the maximum number of views by forum members.

Below are some additional forum policies in hopes of all iboats members will follow, Thank you.

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

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

3. Do not take over someone elseís thread (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 thread of your own.

4. If you have a question for the original poster (OP) and the thread 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 thread.

5. By starting your own thread, 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 thread. And those answers will be specific to your particular issue.

6. Please do not post to threads that have been inactive for more than 3 months unless you are the original poster. We have very active forums and any thread 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 thread.

7. Posting at the end of any thread is considered to be hijacking the original posters thread which in turn subjects the thread 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 thread asking you not to reply to old threads. The Red banner will read: Please note this thread has been inactive for 90 days. For the best results, please start a new thread.

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

  • Late 60's 95 HP Mercury 950 with Thunderbolt Ignition

    I recently purchased a 1983 boat that had a late 1960's KIEKHAEFER CORP. MERCURY 950 95 HP SIX with a model No. 2212108. The only date stamp that I was able to find on it was a date of 1967 on the distributor body. It is a complete running motor in very good condition with throttle and ignition in same housing, along with mechanical and push button choke as part of the throttle quadrant. I've been told recently that this may have been a limited production model between the times of engines able to start in gear to those that were federally mandated to only start in nuetral. I also was told that it had a nickname of " the tower of power " or " the 95hp tower of power " and is a sought after engine as a " nucklehead would be to a Harley collector. I would appreciate any feedback about this engine and would be interested in owners manuals and or shop manuals for it as well. Thankyou for your assistance. Reed

    Merc came-out with the popular 4 and six cylinder inline engines, and they all assumed the nickname, Tower of Power",because they were noteably under-rated when it came to thier claimed HP. The 115HP acts like a modern 150HP.The Clymer manual #B726 covers this engine. They were the king (IMHO) when they came-out.As far as the knucklehead of outboards, perhaps. But outboards don't hold the same obcession as do the old Harleys,regardless of how clasic they are. I don't know why not,as I find the old Mercs a marvel of yankee 'enigine-uity', and a thing of beauty on the back of a clean classic Glastron hull.

      Your motor is indeed a 1967 model. The serial number lookup table is listed on the web at http://www.pfs-ware.com/kwast/merc_s...erence_gui.htm Other than the all too frequently suggested water pump impeller replacement and new oil in the lower unit, there is very little required to keep that motor running good. Make sure you keep fresh gas in the tank, don't forget to mix oil 50:1, and prepare the motor for storage each fall by spraying fogging oil into the carburetors and spark plug holes. Oh, and don't EVER hook the battery cables up backwards or crank the motor without the spark plug cables connected. Either action will immediately cost you $320 for a new switchbox. I learned that the hard way :-(Parts availability is becoming a challenge, but a bit of creative scrounging can turn up most any part. I've found several parts for my '69 Merc 1000 overhaul project on e-bay. My original plan when I had to pull the power head to replace a reed valve was to scrap it after finding several other internal problems caused by the reed valve making it's way into the cylinder, but after some of the more expensive broken parts showed up on e-bay I decided it would be better to keep the old motor running. Hopefully you won't have my problems, but if you do you will know that parts are available if you look hard enough.

        I have the same motor, the power is incredible , i get the same top end as a newer 125 with more torque out of the hole. The only problem i have with it is the distributor slippin on its shaft, and it stalling when that happens. Does anyone know if this can be fixed or if i should be buying a new distributor with shaft?Thanks

          Re: Late 60's 95 HP Mercury 950 with Thunderbolt Ignition

          I have recently bought one too. My serial number is 2211523, i believe that makes it a 68. Looks like they only made them for 67 and 68. Got ours running today, but there is a cracked fuel hose towards the top carb, so will needta change that out. Seemed to start easily tho and run ok. I dont see any water coming out of the top of the lower unit so im guessing the water pump impeller is shot. Will take a look at that soon. Anyone have any insight on how to replace that? Thanks
