I have typed this message 3 times while logged in, but it keeps stating I'm not logged in while trying to post. One more time...
My boat is back in the shop for the third time, and can't seem to fix the problem. Started a couple months back when I was fishing. Boat was running great until midday, then tried to crank motor and wouldn't fire. After several minutes and assuming I flooded it, let it sit for 20 minutes and tried again with the same result. Another 20, same result.
Pumped primer bulb on fuel line (it was soft) and fired right up. Throttled up to come on plane and dies...won't restart. Pump bulb again and fires right up. After repeating 3-4 times, I receive no-oil alarm. Shut it down and repeat procedure, get constant overheat alarm. Trolling motor back to the ramp!
In the shop, mechanic changes fuel and oil lines, and replaces VRO. Back on the water, it comes right up and runs great for 2 minutes, then get no-oil alarm. Shut it down and restart, alarm gone. Back on plane and run for 2 minutes, same alarm. Happens a 3rd time, so I run at 3500 rpm to fishing hole without a problem.
Take off an hour later, and run 2 minutes on plane at WOT and engine starts bogging down and dies. Starts right up and back on plane for 1-2 minutes, same thing. No alarm this time, so I assume there may have been air in the line that cleared out.
Ran fine back to the ramp. While trailering the boat, the engine boggs and dies when I hit throttle. Does this ever time I try it, so have to winch it up.
Back in the shop, the mechanic cannot duplicate problem. Runs on dyno for 2.5 hours at various rpms and runs fine. Tightens all hoses and adds fuel conditioner and oil to the gas.
Back on the water, it comes up on plane and runs great across the lake. An hour later, I crank the motor and it starts bogging down and dies when I throttle up. Continues to do this for several attempts, then discover I can pull back on throttle before it dies and returns to idle. Repeating this numerous times, it finally catches and takes off. Does not die while running on plane.
Problem continues throughout the day, then cannot get on plane to return to ramp, so we idle back. I drop my partner and pull away from the dock and it comes right up and runs great. Try to load on the trailer, and it chokes and dies again.
It is back in the shop right now. I am guessing it may be a carb. issue but was hoping to hear a knowlegeable response before they hit me for big money again.
It should be noted that the engine does not start easy. It will fire right up using the choke and key primer, but will not stay running. If I push the key primer again when it starts to die, it keeps running. Must do this numerous times until it warms enough to idle. It coughs and sputters alot when cold, and normally have to restart 4-5 times in the morning. It is much easier to start as the day goes on.
Can anyone share some insight as to what the issue might be?
