Engine has been running fine for 2 years when I tried to pull a skier and had about half power at full throttle. At same time I noticed the tach was buried beyond 6000 rpm and read 500 rpm when engine was off. We were able to run engine for a few minutes at which time power returned and I...
:confused:Since there is no evident fluid leakage I focused on the valve. My valve body photo
is attached. Its from a '92 (I think 120 Hp). There is a small chip in the surface of the
slot just "north" of center . Can this be the cause of the leakage? If so where can I get
parts or a...
My 120 powertrim woeks fine both up and down but allows the engine to fall over about a 5 minute
period. The fluid level is fine, so I am assuming that my cylinder seals are leaking on the port side
cylinder. Is there a standard seal kit to buy, and is this a difficult job to tackle ?
My 1990 120 hp motor is running beautifully, but just started to leak down on my tilt. Until I can
fix the leak, is there a pin that is available that will protect my lower unit during trailorig. I cant
believe that the design would allow the skeg to fall all the way
to ground if hydraulic...
Just put a replacement lower unit on my 1990 120 horse. Everything seems fine except that I do not
see any water exiting the lower leg during high speed. At lower speeds, it appears as if there are two
hoses exiting the unit. (plenty of flow). Is this normal ? Replaced the impeller at...
My 125 hp is running low rpm at wot. Max rpm was between 3000-3500 this yesterday. Its a new engine for me, so haven't done a compression check
yet. All 4 plugs were face coated in a hard thin burned film of carbon. I am
changing the plugs, but am wondering if this is normal? What else...
Are L drive lower units compatable with their regular corresponding HP and
year models ? eg. Can I put a 1990 120 hp ldrive lower unit on a 1990 120 hp regular engine ? Does the exhaust location matter?
I just found out that my overheating and restarting problem was caused by a fried (nearly dry) lower gearing unit. I'm now looking at a used lower unit from a 1991 90HP to put on my 1990 120 HP engine. Both units appear to be dual exhaust and compatable. As long as I have the shaft and...
I removed my lower unit in order to inspect the pump impeller. In so doing, I
found that the prop spins freely in nuetral, but locks up when the shift rod
is extended in either direction. I can not move the prop at all when in forward or reverse.
Is this normal ?
My recently acquired 120 idles well for 5-10 minutes then dies quickly as if
a kill switch is involved. Once it dies the starter has a hard time turning the motor (as if it has tightened up). Head is relatively cool since we removed the thermostat. Compression reads 145 on all 4 cylinders...
Just bought a 1990 Maxum with a Force 120 Outboard. Before putting it in the water I had the local marine mechanic take a look at the lower unit and run the system with muffs. Everything looked ok and ran well, although water throughput was lower than he was used to seeing with other...
