    Lower Unit Seals

    Mine was hard to change on a Merc 1983 70 that sat in a yard on a boat for a quarter century. I have many tools and seldom buy any but at Lowes the smallest nail puller tool did the trick.

    2 Stroke vs 4 Stroke Torque / Power Curves

    The guy above that said 2 stroke will ALWAYS have more torque, speed and power is right. Yoy see many high end boats today with 4 or 6 outboards on them, that 2 would do with 2 stroke, not to mention that the Evinrude 8 still holds the worlds speed record!

    You seem the guy to go to for info on this outboard and you have one in the cellar to boot and know a lot about Mercs. Can you tell me or send a photo or diagram of where the battery cables are attached to the outboard. I can guess, but spent a lot of time cleaning as many terminals with rust...

    Yes, is the manual choke a back up as the solenoid type kind of looks not reliable! Wonder where I can get a choke bracket.

    I had to go look at mine again to make sure I was not missing something, and mine is not like this with no fixture for a manual choke. IT is hard on mine to get that weighted tube up into the round assembly (not much room) so I will just let the small cable hang there.

    Me either, I think it was a ghost wire that had me stumped thinking it was part of the electric solenoid system. To make sure it hangs up on anything I will cut it off as it serves no purpose. Fastbullet must have a lot of experience and/or an original Mercury shop manual too.

    But there is no manual choke knob? The enrichment solenoid is electric and has a yellow wire with black stripe going to it which would negate the need for a manual choke. Maybe other models had a manual choke and this ring terminal just waves in the air not doing anything. Model serial is...

    Setting Timing on a 75hp 4 cylinder

    Yes, you must do those things first. No fuel, I usually take the plugs out for a lot of things. Never have done the procedure for timing, running or not.

    This is so frustrating, as I can find little in online manuals or the seloc paper shop manual which the online ones are seloc also. What does anyone think of this. Take off the whole airbox on front of the engine and reroute starting wires AND that crazy choke/enrichment solenoid. That box...

    I thought you could set it just spinning the flywheel with the starter?

    ALTERNATE LOWER UNIT

    Internal reeds I believe, manual tilt. Not sure, but they did a lot of changing things in those years. Cylinders are good and fairly high compression 130 ish. That choke/enrichment valve, depending on who is doing the writing of the manual it seems, seems kind of jury rigged, maybe one reason...

    PROP STUCK

    good advice will try after soaking a while yet in trans fluid, acetone and marvel mystery oil.

    ALTERNATE LOWER UNIT

    I will look at the top cylinder with an endoscope. It is also displacement at only 49 ci. that went up in 1984 to a big increase. Have a light ply and epoxy cruiser that I am restoring with a light transom that would work great with this outboard.
