Re: w o t ?? what should it be at on a 3.0
to answer the list of possiable issues i will go one by one
1. Fuel condition. Type and Octane possibly old fuel
fuels was new and i think it was 87 octane
2. Propeller pitch or diameter, damaged blades
posted what is on there in previous post
3. Restricted fuel pickup tube or anti siphon valve
i will check that over the weeken
4. Crankcase oil volume, high oil level can cause aerated oil and lifter collapse
oil is new and just below the full mark, still clean
5. Marine growth on hull and outdrive
there is somthing on the hull,it is dried, io am thinking it to be dried moss, i am trying to figure out how to take care of that now
6. Wrong gear ratio in outdrive
the out drive has 3.0liter engraved in it from factory
7. Restricted carburetor air intake (clogged flame arrestor)
it was left loose and not bolted tight
8. Restricted exhaust system (broken exhaust shutters/flappers) in engine transom shield or drive
9. Poor cylinder compression Compression Test
will run one over weekend-did notice air coming out of the fent tube that goes to flame arrester
10. Carburetor defective, or wrong type.
was rebuilt
11. Fuel pump pressure and vacuum
12. Boat overloaded, improperly loaded, or improperly trimmed.
i had every one in the bow area to keep it down, once again i am new to the trim then i had it all the way down
13. Engine Overheating
run about 150-160
14. Engine timing and ignition system operation
timing light was not working didnt get a chance to check it planned on replacing light and rechecking-- what should it beset at @6-800 rpm idle?
15. Remote control cables and linkage for proper travel to open throttle plates fully.
i will have to double check this one, once again when i get home tomorrow
i hope this helps some i have also changed the spark plugs out put bosch back it (that is what was in there) but i did notice that the plug wires at the cap had teeth on them and seem to fit loose but the cap was smooth like one for a car. now this is my first boat is it supos to be like this?? and once again many thanks
