wide open throttle. Wot. Your motor has a recommended wot of 4200-4600 rpm.
You have a cuddy ? We cut a hole in the deck of my friends cuddy and it was water logged we did pull out about 300 pounds of wet foam.
What pitch are you running ?
I read you last post you didn't say you rebuilt it.
Ok say there is no water in the hull. Maybe you have water in the fuel. Follow the fuel hose to the tank, unscrew the 90% fitting.
That fitting is a one way valve make sure it's clean.
Crank the bow up ans stick a hose into the back lower corner of the tank and pump out the gunk and water off the bottom. Reinstall the fitting and hose.
The carb has a filter in the fitting that enters the carb clean it.
[FONT=Verdana, Helvetica, sans-serif]Get yourself down to a auto parts store, get a can of berrymans carb soak comes with a screen in the can, like a deep fryer.
Also get a can of compressed carb cleaner.And a carb rebuild kit.
With a clean area on a table or bench i place a old cookie sheet with sides.
Break down the carb and remove all the rubber.
Remove the jets they should just screw out.
Everything goes into the berrymans, let soak for a few hours.
Well it should be a couple hours a beer and a little work another beer and a little more work hell might be 5 hours who knows.
Remove the parts from the berrymans, start with the lower carb housing and blow it dry with compressed air, it clean?
Piece by piece build it, make sure every passage is clean blow it dry and use compressed can carb clear blow it dry again.
Jets clean, Float, floating no gas in it ?
Push the float under water and if you see bubbles it's time to replace it.
Ok when you install the pin in the forks that hold the float are they pressing on the float tounge and not allowing the float to move freely ?
So if you did your job correctly the carb should operate freely, and when you install the adjustment screws be gentle.
Do not bend the tips. All the way in with them gently and out 2 turns to start.
Final adjustment on the water.
Have someone else drive about 2000 rpm maybe a little more and you do the final adjustment.
If you take your time and there are no distractions, you should be ok.
Good luck ![/FONT]
List of possible causes of low WOT
List of possible causes of low WOT (Wide Open Throttle) rpm.
In no particular order
Engine Won't Reach Operating RPM. Check
1. Fuel condition. Type and Octane possibly old fuel
2. Propeller pitch or diameter, damaged blades
3. Restricted fuel pickup tube or anti siphon valve Fuel System Test
4. Crankcase oil volume, high oil level can cause aerated oil and lifter collapse
5. Marine growth on hull and outdrive
6. Wrong gear ratio in outdrive
7. Restricted carburetor air intake (clogged flame arrestor)
8. Restricted exhaust system (broken exhaust shutters/flappers) in engine transom shield or drive
9. Poor cylinder compression Compression Test
10. Carburetor defective, or wrong type.
11. Fuel pump pressure and vacuum
12. Boat overloaded, improperly loaded, or improperly trimmed.
13. Engine Overheating
14. Engine timing and ignition system operation
15. Remote control cables and linkage for proper travel to open throttle plates fully.
