    Gentlemen Greetings. Is there any specific tools needed to disassemble the lower unit? I don’t own the manual at this time either. I am going to help its new owner/friend solve this problem. Never serviced a lower unit that far in. Part of the repairs I’ve done already include the water pump...

    Can you circle the parts in question on the diagram for me so I know what I’m looking for? Also would there be evidence in the gear oil if damage to said parts?

    1967 evinrude 80 hp need help.

    I have no idea how this happened. It ran flawlessly for me the few times I took it out. Probably drove the boat 6 times throughout the repairs I did to get it running. He bought it from me at the end of the winter without test driving it. I had no reason to believe it wouldn’t drive as well as...

    1967 Evinrude Speedifour 80 hp. Lower unit leaking?

    I bought the complete seal,housing,bearing assembly last fall because it was cheaper than just buying the seal and bearing separately. Rebuilt everything and filled it. Was planning a last boat ride in the fall. I came out the next day and there was a gear oil puddle on the floor. I walked away...

    1967 Evinrude Speedifour 80 hp. Lower unit leaking?

    Did not do pressure test. Spring is in the correct position. New o rings on the 4 screws. 100% it was new gear oil. Was thinking of polishing the shaft. What about the large o ring on the assembly/housing? I’m assuming it is a back up in addition to the shaft seal? The shaft is still...

    He all. I’m back with more questions on my 67 Evinrude. 80 hp lower unit. I have completely rebuilt it with all new seals because of water/oil contamination.

    I got the cable out and opened two small windows in the cable with a cut off wheel. Cleaned it out with brake parts cleaner then some PB Blaster. Took a few hours. Back and forth, back and forth…..Seems that only the last two feet were effected by the grease pumped into it over the years. It...

    1967 MFG Sprint. Steering cable Help

    I have looked high and low for a cable online, unfortunately can’t find anything that remotely looks like mine. I wanted to keep the original steering wheel.

    1967 evinrude 80 hp need help.

    That’s the problem…. it’s letting water in, and making a milkshake. Don’t suppose using a oil additive (Lucas stop leak) would swell the seal enough to stop the leak? The complete assembly is available $175 if I remember correctly. Comes with bearing and seal. Your thoughts? Thanks again.
