Re: Chrysler Charger 140 Hp

Merc dealers can help with what parts are still available for the more challenging items. Most of the normal maintenance parts can be found right here on iboats. They're twisted pretty tight. The more horsepower you make out of a powerhead, the shorter it's lifespan it seems. Finding used controls shouldn't be too much of a challenge. Ebay and tcoutboard.com come to mind. You can even adapt newer controls and SAE cables rather easily. I believe the main harness connections are on a terminal strip, so adapting other wiring harnesses isn't too tough if you know which wires do what. The terminal strip is probably labeled by Chrysler color and function.

Now I just gotta ask. Might sea star refer to the make of your boat? That's the make of my boat.

Re: Chrysler Charger 140 Hp

I have one with the electronic distributor -- no points. Very nice engine as were all Chryslers. Starts on the first crank every time.
Same basic block as the 100, 105, 115, 120, 125, 135, and 150. so most parts aside from pistons, heads, and crank are interchangeable. This block was the largest displacement of the group with a 2.86 stroke and 3.375 bore, giving 104 cubic inches. Basic 100 to 120 had 2.80 stroke and 3.3125 bore for 98 cubic inches. 125 had 2.86 stroke and 3.3125 bore for 100 or 101 cubic inches. 115, 135 and (I think) 150 had 2.80 stroke and 3.375 bore for 102 cubic inches. Your 140 has the large bore TC carbs with somewhere around .098 jet size. The only larger jets were on the racing 150 with pipes and they were something like .120.

Strangely enough, (I don't know how Chrysler kept track) there are no diagnostic marks on the crank--none that I have seen--the only way to know if you have a long stroke is to put it in a block and measure it. The block itself though, had red paint marked on the bottom of the #4 cylinder jacket--only visible when engine is disassembled. The exhaust ports are raised up about .060 inches to maintain the same timing with the longer stroke crank. Compression was the highest of the group with 155-165 PSI

Any Chrysler, US Marine, and most Force controls will work. Engine end cable quick connect fittings did not change from the 1960s until at least 1990. Cables were always the teleflex generic cables with threaded ends.

Electric hook-up of the cable should be marked on the exhaust cover. This engine uses the white wire as signal to the tach, and the blue wire as power to the electronic box. If you don't have the wiring, Startig at the top: Yellow (start) , Purple (not used), White (tach), Green (choke), Orange (overheat indicator or temp gauge whicever engine has), Red (power), Blue (power to electronic box), Black (ground). This wiring is the same on any Chrysler 3 and 4 cylinder engine with Motorola ignition.
