Firstly.. Thanks for the help so far with my 1954 7.5 evinrude. Thanks to this forum and all you guys, i have torn it apart, and got it back together. And.. It actually ran in the barrel yesterday very briefly. I had to shut it down quickly after no water was spraying. SO..I have used the search, and i am waiting for my manual, but would like to have it runnung today if possible..we finally have some nice weather in maine, and the season grows short.
I need to change the impeller. I know the kit # (thanks again FR) and i want to install it today. I have done an 18hp, but reading some posts, it looks like there is something under the flywheel to remove as well. Could the experts run it down quickly for me please? Is there a shaft under there somewhere that needs to be disconnected beforehand? Thanks..
Oh.. And this motor has a screw hole that says water flush on it.. if i run water thru this, will it mean the water passage is clear?nIs there a hose adaptop you buy for this? Thanks again..

Re: Couple more questions..

You have to remove the powerhead from the midsection in order to access the nuts on the top end of the shift rod.

They used to make a pointy-ended rubber hose end for flushing. Haven't seen one of those for years.

Re: Couple more questions..

Honestly im a little intimidated by taking the power head completely off without my manual here yet. Is there a tutorial available for this that anyone knows about? Im assuming its just the screws holding it on there that need to be removed.. And the throttle assembly before the shift stuff is shown.. Sound basically right? And what are the chances on reusing gaskets i cant find at the local Napa..What i have been doing this morning is trying to spray a bit of carb cleaner in the water passages to opefully free up some crud. Ill snake some wire around a bit in there as well..

Re: Couple more questions..

The powerhead is not all that fearsome to get off.
1: Disconnect the fuel/air hoses (or just take out the hex bolt that holds the fuel connector)
2: Not required, but makes it easier to reassemble if you remove the vertical throttle rod (2 screws)
3: Remove the triangular exhaust outlet from the rear (3 screws).
4: Remove the 7 (?) screws holding the powerhead down. Note where the longer ones go.
5: Lift the powerhead off.

You will need a 303467 powerhead gasket, a 303355 cork gasket, and a 303347 o-ring.

"Plugged up" is wishful thinking.

Re: Couple more questions..

Ok guys.. Bought and installed the impeller today.. Actually started and ran good for a minute, then stalled.. Pumped water like a maniac, but is it from the correct place?.. in picture one, this is where the water is gushing from..can you see the red arrow? Pic 2.. is this submerged deeply enough?.. Covering the intake easily..the water is coming from above the 3 screw triangle piece out of the tube? that runs up and between the 2 spark plugs

Re: Couple more questions..

Nope and nope.

You have blown out a welsh plug in the head. I believe the plug is the same size as the one that sits over the low idle jet in the carb. The water should come out with the exhaust below there. There is a cover held on by three screws on the back of the exhaust tower just below your arrow. I think that is what you are calling the triangle piece. At the bottom of it is a small round hole. That's where the water comes out.

I would prefer to see the water pump at least 2-3" lower in the water since you are testing in a barrel. Once the motor starts water is going to go everywhere! I'd put a couple pieces of 2x4, some bricks or whatever under the barrel to lift it up a little.

Have you run the motor with the cowl on? The plug wires look a little long and might bind. Maybe its just me. Could be an illusion.

Re: Couple more questions..

Ok.. So the next obvious question may be.. WHere might that welch plug be located? I have several welch plugs left over from carb re-builds..And.. is any damage done by running it like that?.. It stayed cool enough.. And when i got it on my transom on a level surface, the water was no longer pouring from that hole.. Just a fine mist, then the carb pisses everywhere like mad after it stalls due to fuel (too much in the carb). Question 2.. In the glass bowl that is under the carb.. Does a filter need to be in there if there is an inline as well? Man.. This is getting to be real work now..When the head went back on, it lined up nicely with the shaft, there isn't a water pipe connection under there that needs to be lined up is there?..If there is, it's not obvious..

Re: Couple more questions..

Not to sound like a smartguy, but the welsh plug goes where the water is shooting out. You need to replace it. There is no water pipe connection at the head.

If you have an inline filter then you don't really need the filter in the bowl under the carb.

Did you rebuild the carb? If you did, I assume you didn't set the float properly or you reused the cork float and its sinking.

Re: Couple more questions..

LOL.. Im a dumbass.. Hah. Sorry for being numb.. Ive been working on this thing since around 8AM this morning..I did rebuild the carb. The float is the newer plastic, and everything should be good.. I have re-built them before, and im quite good at it. I guess what i was wondedring.. Inside the glass bowl there looks to be a threaded hole giong upward into the lower carb chamber. I don't have the original type of filter screwed into that because i lost it. I assumed..(that word again) that it would function as normal and fuel would push the float up just the same without the filter installed. it's old, and i wasn't sure if it had another necessary purpose in there. Your probably be correct, and first thing tomorrow am i will re-install that plug, and re-rebuild that carb. By installing that welch plug, that should re-rout the water to the appropriate places correct?.. And hey Wbeaton.. Your accumulating posts quickly, and sound like you know your stuff.. Thanks to you and Iboats for another great resource..
