See full version: How to winterize engine that won; t turn over
Normal procedure calls for pumping biodegradable RV antifreeze into the flush port while the engine is running But again this engine will not run and I want to avoid further damage. I do not have time to pull this engine out for repair or replacement until next spring. [links]
Freezing temperatures will be here soon and I want to avoid further problems in a non-running engine.
I have a 2001 Challenger with dual 717/720 engines one of which will not start and appears to be seized. It stopped suddenly while boating and I am unable to turn the
power take off shaft by hand with the spark plugs removed suggesting that engine is seized. here
How do I put antifreeze in non-running engine without flowing to parts of the engine where it shouldn't be? more

4. Water or dirt in fuel system
5. Clogged fuel filter or screens
6. Motor not being choked to start
7. Engine not primed -- pump primer system
8. Carburetor adjustments too lean (not allowing enough fuel to start engine)
9. Timing and synchronizing out of adjustment
10. Manual choke linkage bent -- auto choke out of adjustment
11. Spark plugs improperly gapped, dirty or broken
12. Fuel tank primer inoperative (pressurized system)
13. Ignition points improperly gapped, burned or dirty
14. Loose, broken wire or frayed insulation in electrical system
15. Reed valves not seating or stuck shut
16. Weak coil or condenser
17. Cracked distributor cap or rotor or shorted rotor
18. Loose fuel connector
19. Poor engine or ignition ground
20. Faulty ignition or safety switch
21. Low cranking speed
22. Low voltage to ignition, when cranking
23. Low Compression
24. Safety Lanyard/Kill Switch disconnected
Check out this list of 25 reasons why your boat motor won't turn over or boat engine won't start. Don't spend your time aimlessly poking and prodding; instead use this list to help identify the problem. Chances are the answer to your boat engine problem is somewhere on the list. Or, at the least, the list will help you identify the actual boat engine problem you're experiencing. [links]
Boat fuel systems can sometimes accumulate water and dust that prevent the engine from operating properly. If there is water in your fuel system, you will be able to see a separated and defined layer of water under the fuel. Drain the water and change your fuel filter. If you can see dirt accumulation in the fuel tank or filters, flush the fuel system, then refill it with new fuel. more
If the manual choke linkage in your marine engine is bent or dented, the engine may not start. If the bend is small, you can often readjust it using a hammer or pliers. A larger dent or structural damage to the choke linkage may require a complete replacement. If your boat’s engine has an auto choke, it may go out of adjustment and need correcting.
To provide a truly personalized boating experience, Formula Boats even offers both sterndrive and outboard engines for many of our powerboat models. Whether you prefer the sleek look of a sterndrive or value the fuel efficiency of an outboard, Formula has the powerboat engine for you. more
If your starter engages, but the engine cranks very slowly, your boat battery may be low. If the engine does not turn over at all, the battery may be dead. Check the voltage of your batteries with a voltmeter and charge the batteries to about 12.6 volts for a full charge. If the battery will not charge or does not hold a charge, you may need to get it replaced. more
Another reason fuel may not be flowing to your marine engine is if there isn’t anything in your gas tank at all. Even if you’re positive you remembered to fill up after your last boating adventure, it doesn’t hurt to double-check — or to bring some extra fuel along just in case.
