If you are replacing the bearing anyway, it doesn`t matter what happens to the bearing. Heat up the bearing over a flame getting it Very hot, the putting a shifting spanner os other spanner that can slide ofer the shaft but not the bearing, and hit the spanner with a hammer and that should move the bearing, Repeat until bearing is out.
*NOTE* Mark the shaft with something to show where the new bearing should be ( do not use a marking pen, it will burn off, use some thing metal but dont damage the shaft.)

SOURCE: 2001 mercury 25 hp will not go in reverse

Disconnect your shift and throttle cables, they may be reversed. See if the engine will shift now by hand. If it does not, then the problem was created when the shop benched the gear box and reinstalled it. Take it back even if it was last season. This kind of problem usually does not happen by itself.

SOURCE: mercury outboard 70 hp 1987 when in forward gear the prop turns one way when in neutrel spins both ways when in reverse the prop is locked both ways is my lower unit working property

mercury and others have a "sawtooth" cut for forward gear so the prop will rachet spin backward when dry tested, and a square clutch dog for reverse, which when it finally engages locks the prop in reverse. and will not spin in either direction.

So when you shift--- snap in in gear-- do not ease it in gear, as it will wear the dog out faster.

Mercury 150hp Optimax outboard


clean the connection on the back of the tachometer and on the sensor in the engine. If the engine remains at 2,000 rpm and won't go faster, you need a marine engineer with diagnostic equipment. That is a big engine on an 18 foot boat!

Tip

Outboard motors


Keep the gas in your outboard new/clean with new oil every 6 months..Keep your motor covered when not in use, Dirt dabbers (dobbers) will build nest under the hood and break loose and ruin your motor, ,,Change your water pump and thermostate every year when motor is used a lot.....Dont run stainless steel props on small hp motors ,when you hit a log it will bend your prop shaft costing big $$$ to replace..Ck your lower gear oil if water is noted ,replace lower seals...Dont buy used motors unless you run a compression ck....ck for water in gear case , Dont buy 4 strokes to heavy to slow to many parts AND are being replaced by fuel injection 2 strokes .... Dont buy FORCE motors not made by mercury no parts being made and or extink and pure junk . Etex best motors , .

I have a mercury 9.8 hp long shaft outboard serial #7144669 Do not know what year it is. Need a new prop. I live in Vancouver BC Canada Any Suggestions? Bill


props are available from any boat shop or on e-bay
if you prop problem is a failed rubber insert, they can be replaced by any accredited boat shop
what you need to know is the pitch of the prop as there are at least 3 different pitches depending on what you do with the boat, before you purchase on line

Water pump


The water pump is a flexible impellor located in the top of the bottom section of the leg of the outboard. It is driven by the drive shaft to the prop that is spinning all the time the motor is running. You will find it behind or near the water inlet slots at the bottom of the leg

I have a 2002 ox66 Yamaha 2 stroke 250 hp std rotation outboard. The propshaft snapped off. The fluid is clean and remaining shaft spins freely. Can i remove the two flange screws and carrier and pull out...


Prop shaft. You have to remove the bearing housing cap. reference number 70. Remove the bearing housing. reference number 60. The bearing housing will need to be pulled out buy using a puller. If it was in salt water it can be difficult. Pull the prop shaft and clutch dog assembly.

I have a johnson outboard motor that drips oil from the prop.why is this ?,maybe a seal is blown?


Yes the prop shaft seal needs to be replaced.Do this sooner than later as water will get into the lower g/box.Sometimes they wear out or fishing line is a bad culprit.Its not a big job but it really needs to be done.The oil will also need replacing.Hope this helps
