Evinrude 150 ,,General Question,,ANSWERED!!

[LGreen6646]

1996 Skeeter and Evinrude 150 (Intimidator) motor<br /><br /><br />Hey Guys,<br /> I put the flusher hose on again and it still didn't **** water through the tell tale port. I pulled the thermostats and water never got to the t-stats. I pulled the lower unit off and the water pump was in excellent shape, pliable, and sealed good. So what was the answer,,,THIS MOTOR CANNOT USE A FLUSHER AND HOSE,,IT MUST BE SUBMERGED. After working on the unit for about 3 hours we took it to the lake and submerged the lower unit at the boat ramp, the pisser pissed perfectly and there was no problem. Why does Evinrude do this?????? Thanks for all the responses left from my previous post.<br />LGreen

I can only think that you are getting a lot of air around the flushing attachment. If you have the correct attachment, and it is attached correctly, it should work. After all! you are force feeding it water. Will the engine maintain a prime when the boat is up on plane, besides just idling at the dock?

LGreen....this may be a dumb question but, did you actually start the motor on the muffs? Water will not make it to the engine on the muffs if the engine isn't started. The water enters the impeller housing on one side and exits on the other side because the impeller pushes it out. And if the impeller is in as good as shape as you say, you had water just to a place inbetween impeller blades.

Re: Evinrude 150 ,,General Question,,ANSWERED!!

Yes, the motor was started and ran during all tests. We pulled the t-stats to see if water was getting to them, it wasn't. We pulled the lower unit and everything was fine. We submerged the lower unit in a barrel and it primed and peed through the tell tale. We used the flusher again and notta, nothing at all. We took it to the lake and it worked perfectly, I haven't taken it out on plane yet, hopefully tomorrow.<br />LGreen

Do you have the plug in by the rear of the engine under the cowling. You would remove this plug to hook up the hose if you want to flush it without muffs.

Re: Evinrude 150 ,,General Question,,ANSWERED!!

I am so lost on the last reply, is there a place under the cowling to do this. Are there muffs that can be used on this motor, is anyone really sure if you can use a hose flusher on this motor, the motor is an 95 Intruder 150? At the top of the post I called it an Intimidater.

Re: Evinrude 150 ,,General Question,,ANSWERED!!

All I can say is if muffs didn't work the problem was with the operator not the muffs. You were doing something wrong. maybe not enough hose pressure, maybe the muffs were in the wrong place. ......

Re: Evinrude 150 ,,General Question,,ANSWERED!!

I really can't think of any outboard OMC made with a one piece gearcase that can't be run on muffs, from a 9.9 twin to a V/8. On each side of the gearcase, and just below the cavitation plate is a water inlet. Did you have the muff's over both of these inlets. I don't have a clue as to what plug bonitoman is talking about at the rear of the engine. If water went through that engine running at the dock, it has to go through running on a hose. As I said before! you are force feeding it. Here is another thing to keep in mind! that tell-tale stream tell's you the pump is working, not that the engine is cooling. This is especially true of engines' with the bubble back exhaust.

Re: Evinrude 150 ,,General Question,,ANSWERED!!

Well, I KNOW that any operator on this particular motor couldn't get the ear muffs to work. I have used muffs many times on my Mercury without any problem. Never had a problem on a Yamaha or Mariner either. I do know that when the tell tale pissed, that the heads were cool to the touch and that the tell tale stream was very warm. The temperature alarm has never alarmed during any of the tests. I will find out tomorrow when I take it out.

RJ...LGreen....maybe just a shot in the dark, but look at the plastic strainer insert that keeps junk from getting through the water intake and see if it's lose. Maybe when you apply pressure from the muffs, the darn thing might be lifted up and keeping the water from the pump????? Darn if I can see anything else that would prevent using muffs on that engine.

Re: Evinrude 150 ,,General Question,,ANSWERED!!

Drop your lower unit and take a garden hose and direct the water into the copper tube to verify that the engine will pee. Do not run the engine!!! If water pees out then the problem is somewhere in the water pump or where the water pump goes up into the copper tube.

Hey Guys,<br /> Took the boat out today and ran it for two hours, from 800-5700 RPM's, the motor ran perfectly, never lost the prime. I still cannot get the muffs to work though. I have pulled the strainers and checked for obsticles, none. This has really got me baffled with the muffs. <br />Thanks Guys,<br />LGreen

Re: Evinrude 150 ,,General Question,,ANSWERED!!

You've either got a faulty (plugged) flushette (muffs), or you are not turning the hose on full blast..... or you are yanking our chain!(grin)

Re: Evinrude 150 ,,General Question,,ANSWERED!!

Man,, I wished I was yanking your chain. I REALLY don't know what to think. I guess I just need to eat some humble pie, funny how a little thing can kick your butt. Plenty of water coming out of muffs and water pressure checked at low, medium, and full open faucet. I DON'T KNOW.<br />Thanks,<br />LGreen

Neither do we.....

Re: Evinrude 150 ,,General Question,,ANSWERED!!

Let me take a stab at this. very possibly your water tube is not connected to the pump when you put the lower unit back on. Muffs will not work due to insufficient VOLUME. When on the boat and running there is sufficient ram effect plus water pump volume to fill the leg up to the water intake on the lower part of the block. Therefore is doesn't overheat and pumps water. WAG ( wild ### guess but as good as the rest so far ) nevjb
