The iboats forum moderators are excited to announce that at this time it appears the iboats forums posting pictures function is working once again. Though we cannot promise for how long, we're hoping for indefinitely.
If I unhook it off the coil and do everything else the same at the dock, will that be a way to test it.
I want it eventually to stop dripping when I shut the key off. That was the initial problem I wanted to fix. Everything has become worse when I went to the lower pressure pump.
Yep. For an old girl it was 135-140psi.
So check under the distributor to make sure everything is set perfect.
The carb specialist(I would just take it to him to fix but it is 1.5 hrs away) always texts me back tries to help. He told me to vent the gas tank, to see if the rpm lower will stay...
So I thought my pump was causing the flooding problem. It measured 6-7.5 lbs output, so I put the fuel pump I’ve always run. Now it won’t get anywhere near idle. When I undo the fuel line at the carb, it pulls off and squirts as if it was under pressure, like couldn’t get in the carb
With the 4.5 psi pump on now it wont run below 2200-2400 rpm. If I bring the throttle below half throttle at the dock, it just dies out. To start I put neutral 3/4 just to get it going again
I opened her up last night. I have it like the schematic you sent me. When it’s up it is 3/8 of inch from gasket to toe.
When it drops(on dry land - air horn off in my hand) it is less then 1 3/4 inches hanging down if I measure to the exact same spot.
Post about my Mercruiser now. Carb floods so I checked the needle and seat, re-cleaned everything. Boat works ok. Shut key off and gas drips from venturi’s a bit.
Thought it was the mechanical fuel pump, so I put my other one on. Pressure test at 4.5lbs. To start the boat I have to give lots of...
So we know that the exterior coils are ok. I ohm tested them. My dad is impatient and he bought new one’s without telling me. Still no spark to top cylinder.
Thank you for answering. We are up in Canada, no salt water. But good tip.
It is a special motor. It has 4 coils, two with the magneto and two exterior. It actually charges the battery to run other stuff while it is driving...

My dad’s Mariner on the back of his sailboat always has run great. Started to lose power and just run on 1 cylinder. The top spark plug was always wet. He boat a new secondary coil(nice grey one, attached on the outside of the motor with wire going to spark plug). Put it on...
