1995 Johnson 140 HP. I changed the timer-base and power-pack with new CDI parts. (Motor was surging at highspeed)
I found orange and orange black wires on stator cracked and shorted together when I remove the stator. Anyway. I repaired that too.
I timed WOT as per Joe Reeves method. I set...
1995 Johnson 130 looper. I replaced my VRO with a mechanical pump. A mechanic recommended the pump and I took his advise. Is a single pump going to deliver enough volume for this motor?
1995 130 Johnson. Runs good until WOT. I see a flood of bubbles in my inline filter when I open up the throttle. So much air that the filter is only half full. The filter is between the primer bulb and fuel pump.
Motor will start surging. I slow down and bubbles disappear and runs pretty good...
1995 Johnson 130 HP Model J130TLEOA.
I keep getting what appears to be shredded rubber in the carbs. I have 3 fuel filters.
Whats going on?
Thanks,

I'm replacing a sheared flywheel key on a 1995 Johnson 130HP.
It uses the half moon type key. It doesn't seem to fix right.
The key-way seems shallow. Is this right? Please see attached photos.
Had an intermittent misfire. Replaced power pack, rebuilt carbs, and replaced timer base with a used one. I did find a loose flywheel with a bad key. Possibly causing the problems. Anyway, It Started up for a few minutes but now I have no spark at all. All cylenders lost spark at the same time...
I have an 80 gallon tank under the deck of my boat. I was getting trash in the carbs so I started siphoning the fuel out. I got a lot of water. I'm not sure where the water is getting in. Is there a way to test a poly tank for leaks without removing it? I can not remove the tank without...
I purchased a boat with an uninstalled Moeller water separation filter. The previous owner didn't have the instructions.
It has an input and output on the left and the right for a total of four connections. The two on the left have plugs in them the ones on the right have hose barbs on them...
1977 9.9 HP M10R77A
Before the carb rebuild, the motor would crank easily and I never used the choke. It had lack of wot power and would not idle well, so I rebuilt the carb.
After the carb rebuild it idles great and sounds more powerful but it is difficult to crank. At first I have to crank...
1977 Johnson 9.9 10R77A
Compression-Just checked it.
1=100
2=100
Spark looks good on both plug wires and feels pretty strong running through my arm. (don't ask) :)
It seems to lack power. I can't quite get a 12' joh boat with 2 people on plane.
I removed the plugs and they look ok, so I...
I'm looking at a 1976 Johnson 4HP 4R76M.
It has pull start only.
I didn't warm the motor up and didn't put it full throttle because I didn't know I should.
The top cylinder has 60 psi
The bottom one has 90 psi
It will crank up and run in a bucket. It took about 6 pulls to get it started.
The...
I recently got took on an outboard motor deal. The motor started right up and ran fine in a bucket of water but on the lake it had no power. Turned out that it had no compression on one cylinder. What steps should I take to check out a used outboard before purchasing it?
Thanks!
:redface:I don't know if this is the right place to ask this, but here goes.
I have a 1975 Mercury 500 50HP. Low compression on cylinder 4. I'm not a good enough mechanic to fix it. So, I want to sell it for parts or whatever someone might want it for. Other than the low compression it looks...
I have a 1975 Mercury 500 50hp and found a used powerhead at a reasonable price. He says the compression is 105 in all four. Does that sound a little low?
My serial number is 3821XXX and the other power head is a 1979 with serial number 4965134. From what I see in parts list his powerhead is...
1975 Mercury 500 50HP. I took it out for a test run today. It was slow to get on plane but gradually got up to speed. It took about 10 seconds. I ran out about a mile before it began to slow down. It gradually got slower and slower. The motor sounded ok but just wouldn't go. I tried...
