    Have 35/40 oil injection lower unit and the prop shaft has about 1/4 inch play forward and backward, anyone what is wrong?

    Got a 35 Mariner Magnum and a 40 Mercury one too. Want to delete the oil injection system on the Mariner (they are both the same outboard.

    Already in the process of making the oil injection back to pre-mix as quite a few folks recommend it! More reliable!

    I just want to know if anyone knows when you take out the carb restriction plate and bump it up to 50 hp do you need to retime/retune?

    The Mariner has a air flow restriction plate I want to remove to up the hp to 50. Do I need to do anything to the 2 carbs after I remove the restriction plates?

    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.
