    Missing wires in ignition system wiring harness (pics incl.)

    This post is in regards to my 1994 70HP Force. I was doing some voltage and resistance testing on my ignition system over the weekend. While doing so, I noticed that the wiring harness butt connectors had two missing wires on the ignition/motor side. I'm not sure if it is clear to everyone in...

    Spark plug voltage?

    I just got a spark tester that has the adjustable gap for helping determine the spark strength. I was thinking that the voltage the coil delivers to each plug is around 20,000 Volts. Does this sound correct for a 1994 70HP Force with Thunderbolt ignition or is it even higher?

    Seeking advice as to whether or not to ditch my Force

    As the subject line indicates I'm having trouble deciding where to go from here with my 1994 70HP Force outboard. My current situation is that I have both very low compression on all cylinders (110, 110, and 90 psi) and a faulty ignition which delivers a weak and inconsistent spark to the lowest...

    1994 70HP Force OEM Prop Size?

    I have a 1994 70HP Force outboard. It's on a 1994 Spectum Dominator 17 which is a a 17' aluminum bass boat, similar to 17' BassTrackers. I was wondering if anyone knew or could point me to a place to find the OEM prop size for this outboard. I haven't inspected the currently installed prop yet...

    Eninrude XP 150hp lower unit compatibility?

    This post is about a friends outboard. He has a 1983 evinrude xp 150 which runs great but does not shift into reverse. It goes between neutral and forward fine though. I don't if he has really looked into the exact problem but it's more than likely a lower unit issue. So my question is what...

    Need a Peak Reading Voltmeter

    I'm in the process of testing my 1994 70hp Force's ignition system. All I have is a typical multimeter though so I have only been able to test the resistance of the stator, trigger, and coils (all were good). I need a peak reading voltmeter for the other high voltage tests but the cheapest one...

    Hey, I'm having trouble locating an impellar kit for my 1994 70hp Force. I have looked on this site at the following link... Force Impeller Kits ...but they dont specifically list my model.

    Ignition Key Switch Replacement

    My ignition key switch has gone bad on my 1994 70hp Force. I think the push-to-choke feature had gone bad as well as the spring action that returned it from start position to the run position. To top it off when I removed the switch and leads to clean everything up with a wire brush the main...

    Tilt Cylinder Leaking - Need Advice

    My motor is a 1994 70hp Force which has sat for a couple of years. The tilt motor went bad over that time and I replaced it and refilled with fluid and now the tilt works fine...however, I noticed the cylinder (or shock or piston or whatever it is technically called) is leaking. It is not...

    Tilt Pump Motor Got Water In It...

    My motor is a 1994 70hp. My tilt system is a single ram with a 2 wire pump motor. The boat/motor has been sitting for about 3 years. In that time, the tilt was occasionally cycled as we would raise and lower the motor and crank it up for a few minutes. In recent days, I began working on the...

    Is 625 CCA Enough for 70hp Force?

    I typically just buy the Everstart batteries from Walmart and they have a 625 CCA marine battery for about $55. Is that good enough for a 1994 70hp Force outboard? They also have one with 720 CCA for $75 which I don't mind buying if I need to.

    Opinion Needed On A 1979 8hp Chrysler

    I have a boat I want to buy that comes with a 1979 8hp Chrysler. It is listed on ebay and the seller says it was last run 2 years ago and ran great then. I asked him to check the compression for me and to put some seafoam in with fresh gas for when he tried to start it. He said he'd get to it...

    70 HP Ignition System Help

    My motor is a 94 70hp. The motor starts easily and runs but it runs a little rough and sometimes at 3/4 to full throttle it cuts out a little and has surges in power. I've replaced the fuel pump diaphram, primer bulb, fuel lines, I have good gas with a can of Seafoam in it, and the tank is...

    Decarb Question

    I took my 94 70 hp to the mechanic recently to see if he could figure out what was causing the motor to run rough and cut out. He said the cutting out was due to the ignition system producing weak and unsteady fire on 2 of the cylinders. He also said the compression was 110, 110, and 90 which is...

    Mismatched Ignition Coils - Which Color Should They Be?

    Guys, I have a 1994 70hp Force. The attached pics show the three ignition coils currently on there. I experienced some high rpm running problems last fall which I never fixed and I have yet to get on the water since then. The 2 lower coils are blue and the top one is black. The black one also...

    Lower Unit Water Leak

    My 94' 70hp Force is leaking water around the shocks on the lower unit. At least, I think its leaking. I don't recall this happening before, but it doesn't look right. I have done some fuel pump and carburetor work but I have yet to get on the water this season. This is my only hold up. Does...

    Fuel Delivery Problem.....Fuel Pump???

    All, I just finished rebuilding my power tilt/trim unit. I was so happy I decided to start her up. Needless to say it didn't work. I primed the bulb and opened the tank vent. I have an inline filter between the fuel pump and the carb which filled full of gas as the bulb was primed. I tried to...

    I have been looking around lately for a fuel/water separator for my 94' 70hp Force. Ive looked at sites like Basspro, Cabela's, Overton's, Gander Mountain, and West Marine and Walmart. Looking at reviews, it appears that lots of people have issues with most of these units for sale on these...

    Broken/stripped Tilt Cylinder Cap

    My motor is a 70hp force. Apparently over the winter, water was in the tilt cylinder and froze. This caused the cap on the top where the rod extends through to pop off and strip the threads on both parts. Everything else about the tilt system works great so I definately dont want to have to...

    Tilt System Fluid/Oil???

    I have a 94' Force 70 hp. One of the lines came loose and I lost the fluid from the hydraulic and the pump. What fluid should I refill with? My force manual says Quicksilver tilt fluid but also lists regular motor oil. The fluid that leaked out was a green hydraulic fluid. Any suggestions of...
