I am new to the forum, though I have been reading the various posts for a month or two. I had a 70hp Johnson on my Whaler, but while running it last Thursday, it ceased moving forward, though the engine ran fine. I pulled the boat, and did some rudimentary checks. Finally, I tried to drain the lower unit...nothing. I flushed it with gas, and the only things that came out were gear teeth and metal filings. After a little investigation, I found that whoever changed the lower unit last had switched drain and fill plugs, not realizing that the nylon washer stayed on the drain plug, while the fill washer stayed in the lower unit. Over time, all of the oil drained out (three weeks), and the rest was history.
I had the Force 85hp on a pallet in the carport, and started switching them out on Friday morning. By Sunday morn, I had the wiring, controls, etc. hooked up, and ran the engine with muffs...it seemed to be missing, but I put it in the water anyway. After idling around the dock, working the gears, etc., I started to push it. It took off with a lot more power than the old motor, and I was very happy for 200 yards, when it died. I checked the fuel line bulb and found it soft, then it dawned on me that I had closed the vent after I stopped to fill the tank at the gas station. I opened the vent, the boat took off and ran fast for 100 yards, then died.
Thereafter the motor would bog when I started inching up the throttle. I sounds like it's missing on one cylinder, though it does backfire occasionally. I am going to work on it tomorrow, but could use some suggestions about where to start. I am replacing the fuel hose and pump bulb first thing, the checking for iginition from all three coils.
The motor has what appear to be three CD units, though I know this is not what my Seloc manual says. Two of the units are royal blue, and the other is black. The manual is very short of detail on this engine, and I had to sort out the wiring on my own, as the wiring charts in the book did not correspond to anything I had on the motor.
The fuel is new, the oil is in the mix, I ran the Johnson off the same tank for hours, and never had a problem. The Force engine sat for some unknown amount of time, but looks new under the hood. Pumps water, starts easily, and went well for a brief amount of time.
All suggestions are welcome. I would include the model number, but the plat is bleached out to the point where I cannot read the numbers. It does appear to have the type three ignition, however.
