I had the old 2 wire. Went ahead and replaced it with the new 3 wire. Still didn't work. Popped in a new coil and it fired up. Sounds like the sensor was a ticking time bomb anyway though.
So I'm trying to diagnose an ignition problem. I read the sticky post at the top. There is a link to how thunderbolt ignitions work. It has troubleshooting steps but none of the images work. Can anyone update it??
One saw it in a picture it does look pretty crusty. Can't tell when it's way in the back of the motor in the bilge. I'll just order a new one and clean my connections. Will update
I replaced my plugs/wires/cap/rotor.
The boat was running fantastic. Started better than ever. Then after 30 minutes on the water it sputtered and died. Now it won't start. It is a 2001 5.0 alpha 1 thunderbolt v ignition carbureted motor.
It won't start on starting fluid either. I got my spark...
I have a 2001 Merc 5.0 with thunderbolt V ignition, carburetor engine. The last two times I've gotten a full tank of fuel the idle is terrible when in gear. It barely stays running. It has been fine once I burn up some fuel. Different fuel docks each time. What gives? Is it possible to...
I've been having an intermittent issue with my boat. It is a 2001 Bayliner with a 5.0 Mercruiser, alpha 1 Thunderbolt V ignition.
Sometimes when I go to start the engine, usually on a cold start (with bilge blower running) as soon as I bump the starter all power to the boat is lost. Almost...
It looks like the cooling hoses for the manifold/risers block the front 4 plugs. Any tips to make this easier? I'm thinking I need to remove the hoses for access.
I bought a new prop this season to help get my boat on plane faster. My boat is a 2001 bayliner 23' cuddy with a 5.0 Mecruiser (carburetor). My original prop was a 15x17" 3 blade, I got 4400 RPM with it. The WOT RPM range on the motor cover is 4400-4800 rpm
I bought a Quicksilver Nemesis...
I just got a 93 Johnson 25hp electric start. Where does the ground for the battery connect? I see the positive connectiom on the solenoid but can't find where the ground goes.
Just got my engine hooked back up. Motor is a 1978 140hp chrysler. My kingpin froze and I couldn't turn the motor. With help from the forum I removed my powerhead and swapped it onto a good middle section. Resealed my lower unit and replaced all the seals in the tilt/trim. I stripped the paint...
Just got my motor back on the boat after doing the tedious task of rebuilding my trim/tilt on a 78 chrysler 140hp. It lifts and lowers but the tilt cylinder is leaking fluid out at the top where the hydraulic line connects.
There's a metal band with a fitting on it and I think it's stripped...
Can you replace the big nut on a steering cable? My tilt tube snapped off inside the nut and I can't get out. Can I cut off and replace the nut or should I buy a new cable?
