This motor has had very little use and has had the water pump and fuel pump diaphragm (Kit) replaced 6 years ago. It ran fine 5 years ago but the carburetor was not ran dry when last used. Just turned it off and stored until now. I'd like to know what general maintenance or procedure I should be doing before I try to start. I plan on changing the lower unit fluid. It's been a great motor and want to take better care of it in future. Any help would be greatly appreciated.

I'd suggest installing a new water pump kit and new Champion J6C spark plugs gaped at .030.

I'd strongly suspect that the carburetor is fouled bad and requires removing, cleaning, and rebuilding.

(Carburetor Adjustments - Two Adjustable N/Vs)
(J. Reeves)

Initial settings are: Bottom high speed = seat gently, then open 1 turn out. Top slow speed = seat gently, then open 1-1/2 turns.

Setting the high and low needle valves properly:

NOTE: For engines that DO NOT have a shift selection, obviously there is no NEUTRAL position. Simply lower the rpms to the lowest setting to obtain the low speed needle valve adjustment.

(High Speed) Start engine (it will run pretty rough), shift into forward gear, take up to full throttle. In segments of 1/8 turn, waiting for the engine to respond between turns, start turning in the bottom high speed needle valve. You'll reach a point whereas the engine will either start to die out or spit back (sounds like a mild backfire). At that point, back out the needle valve 1/4 turn. Within that 1/4 turn, you'll find the smoothest setting.

(Low Speed) Slow the engine down to where it just stays running. Shift into neutral. Again in segments of 1/8 turns, start to turn the top needle valve in. Wait a few seconds for the engine to respond. As you turn the valve in, the rpms will increase. Lower the rpms again to where the engine will just stay running. Eventually you'll hit the point where the engine wants to die out or it will spit back. Again, at that point, back out the valve 1/4 turn. Within that 1/4 turn, you'll find the smoothest slow speed setting.

When you have finished the above adjustments, you will have no reason to move them again unless the carburetor fouls/gums up from sitting, in which case you would be required to remove, clean, and rebuild the carburetor anyway.
 
Oriely's Auto parts gave me plugs they say match it. Auto Life 303 and they are gaped at .030. I'll replace those if they aren't a correct match. It started on the 4th pull and was steady but there was no fine mist at the exhaust port so I stopped it. Went and reread the owners manual which says fine mist from exhaust port. Restarted to be confidant no water mist, just very fine oil feel so I shut her down. Is replacing the water pump kit a difficult job for one who has never done this? I know I'm looking at a carburetor kit but I'd like to see how well it runs after new water pump. I'd like to use this motor next week on vacation. I must had run the motor's fuel dry before storage. I am very appreciative of the members of this board's help.
 
Running in a barrel, large trash can, etc..... the water level must be 3 or 4 inches above where the lower unit bolts up to the long exhaust housing as that's where the water pump sits and it must be submerged... it is not self priming.

There will be more than just a mist shooting out that water/exhaust port when that pump is working properly!
 
I was using a 12 inch deep big pan which brought the water level with the anti cavitation plate. My owners manual says it has a thermostat. I may not had let it warm up enough to open and I never put it in gear. I see it has a exhaust outlet and a exhaust relief, the top one. I had my hand under that because I remember water flushing out of that. I'll bring that water level up over the pump placement and give it 2 minutes maybe and change gears. Thanks
 
Get a 55 gal barrel and put it in there. Or else put it on the boat and try it. That's the true test !!!
 
Thursday night I'll put it in a 55 gal barrel and give it another try. I've got a office meeting (party) Wed night. That's the last thing I want to do after 8 hrs with obnoxious arrogant coworkers. Thanks for your guidance.
 
You can cook a new impeller in seconds running it dry. If you rebuild the carb replace the fuel lines at the same time inside the motor. Afterr each use run it in a barrel of water until the thermostat opens up then disconnect the fuel line and let it run out of fuel. then your all set for the next outing.

Click to expand...

That water pump would never draw water with that setup... and if you ran it very long (4 -5 min) I'd suspect the impeller took a beating.
 
This board isn't their cup of tea and the boss would just take his power boat in the shop. It only ran less than a minute because once it started I put my hand there and no water so I shut her down. You may be right though. I borrowed a neighbors 55 gallon drum and it ran well and it pumped good water through it. It won't run well at idle speed and I'll buy a carburetor kit in a couple weeks. I have a 7.5 Chrysler that hasn't ran in 5 yrs also and it seems to be running like a fine clock, pumping good water out the exhaust. Ran a gallon of gas through it, forward and reverse and all seems well. I'm going on a 30 mile trip on the Buffalo National River lower wilderness area. No access to the river until 30 miles at the White river. If my motors wouldn't work I was going to paddle my 17 ft canoe but now I'm renting a 20 ft fiberglass jon boat. Ozark cruise. Monday - Friday small mouth fishing. When I get back I'll rebuild the carburetor on the Evinrude and I'll be back on here for advice again. Thanks everyone.
