SOURCE: impeller replacing on 1999 merc. 25hp 2 stroke

Should not be that hard. Tape up the ends so you can hold it with out getting cut, (if its ragged or sharp from damage). should be one nut holding the impeller on. If its to tight to hold try air or electric Impact wrench. If its bad you can tap with a hammer to help in removing the old one. If it turned on the shaft you will need to rent a puller. Repost if you need more help.

Sounds like your running a bit rich. Try leaning down your air/fuel ratio.

SOURCE: Re-assembling lower unit of 40HP Mercury 4 stroke

I found a lower gear case assembly diagram at http://www.crowleymarine.com/mercury_parts/6995/240.cfm which helped me understand how the shift mechanism works. This clued me in to the fact that I was missing the cam follower rod which I then found I had inadvertently mopped up in a shop towel when cleaning up spilled gear oil. After that discovery, assembly and operation was quick and successful.

What year is a mercury 35hp outboard motor with serial number2491265.Is the motor 2 or 4 stroke


the serial number begins 2487558 and continues past 2491265 and as the beginning serial number denotes the year , your engine is 1969 model
it shows as a 2 stroke with auto oil injection
check the heads
if the plugs are in the flat of the head and there are no rocker covers it is 2 stroke
talk with a mercury /mariner service center

Mercury 1989 60 HP Outboard Motor manual to find gas to oil ratio


50:1 But if your doing mostly low rpm cruising (trolling) then you could reduce that a bit to 75:1 to help reduce smoke. If you do mostly mid to higher rpm cruising, then 50:1 (1 pint to 6 gallons. )
Or 200mls in 20 liters if your Canadian.

Are the controls for a 1998 15 HP 2 stroke Mercury outboard compatible with a 2011 30 HP 4 stroke Mercury outboard


If your old engine/control has the same 'options' as the30hp, yes everything is compatible... (Electric start or trim )
The throttle and shift cables are allways compatible...

Have 115 Hp mercury outboard motor missing at full throttle and on idle. At mid throttle it is running fine. Any Idea what the problem could be. Thanks, Milton


Have your spark plugs changed AND carbs cleaned and adjusted.
Usually that can also be caused by a seized advance system ( plate under the flywheel, commanded to turn with the throttle linkage... )
