Unfortunately for you, the motor is out of warranty and lower units are not supposed to be cracked under any circumstances other than striking very hard some underwater obstruction. IF water was present when the motor was put away last winter, it would have frozen, expanding in the confinement of the gear housing and causing the metal casing to CRACK. Water WILL then be able to intrude the gear casing and mix with the lube oil in the lower unit leading to a breakdown if you run it without having it replaced. Get it serviced as soon as possible or, at least, get a service estimate without using it further or you'll experience a catastrophic gear failure in the lower unit and find yourself defintely looking for a new motor.

SOURCE: suzuki outboard motor 65 hp --oil sensor keeps

assuming you are not out of oil in your oil reservoir you probably have a bad sending unit in the reservoir. never bypass it or eliminate it as you could permanently damage your motor or ruin it if you ran it out of oil.

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 , .

Suzuki outboard 8hp 1994, at higher speeds under loading prop appeared to cavitae, liek spun prop. repalced with new prop. On the bench, plugs removed, in forward gear hand turn prop thur haft turn and...

You may not be deep enough in the water and it really is cavitation.

May want to check the lower oil for metal as a Mostly worn out gear can do that

It's normal for a gearbox in forward to "click" in one direction and be firm against the motor when turning against the gears normal rotation.

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.

How do I drop off the lower unit on my 70 hp evinrude engine? I believe the shifter fork is worn.

below the carbs is the shift rod and take the small pin out , then remove all bolts that hold the gear case to the leg then drop the unit and place in a vice to hold by the skeg fin below the prop ! normally its the edges of the gears and the central slide clutch that wear, remove and have re cut at machine shop ! saves buyin new gear set !! check all linkages ok for wear FIRST though !!

I have a 1970's 25hp Johnson outboard motor. Last

Hello Adam.
If your propeller is OK, your lower unit will need some repair. It may be as simple as a clutch dog worn and not engaging the gear. Usually they give warnings of problems by jumping out of gear though.
Other possibilities are broken driveshaft, propshaft, or gears. If it goes into reverse the shafts are OK and the clutch and forward gear become suspect.
It was common for these engines to break at the top of the driveshaft where they were tapered.This would give you no motion at all and no previous warning of a problem.
Check the gear lube for metal particles and signs of water intrusion. I hope your repair is an easy one.

Help. recently cavitated my 140 hp 1989 mercury outboard motor at high speed.I Removed the lower unit several times but only goes in forward about 5mph. Please help Tx jack

Not really sure what is wrong.Do all the gears work?Does the motor rev properly.Did you change the height of the motor.If the motor etc. are all ok and the motor cavitated at high speed,you may have spun the bush in the propeller hub.The symtoms are,everything works ok but the boat can rev but will have very little forward propulsion.If this is it,the prop needs to come off and taken to be rebushed.The bush stops major damage to the g/box if the prop strikes something.Hope this helps
