I bought this motor that was attached to a 16' alumacraft, a 1986 40hp evinrude, (e40elcde) from a guy that let it sit unused for at least 7 years. Not to mention i have had it for about a year. well, finances finally started getting right and i bought a starter and replaced some fuses, checked compression, lower unit oil for water, replaced plugs and she cranked right up. does that sound a little odd? i would reason to me that i would have had to rebuild (at least clean carbs) before cranking up. she purrs like a kitten! AM I MISSING SOMETHING OR FORGETTING TO CHECK ANYTHING? Any ideas on maintenance i should do before setting sail? -tryn2fish
 
Re: Am i missing something?

If the carburetors were drained when it ran last , they will be clean.-----The motor will run properly.-------------The water pump impeller is different as it ages with time and SHOULD BE REPLACED.-----------VRO if still hooked up should be bypassed or oil delivery checked.----------Enjoy the motor.

Water test the rig. If the idle is rough and/or the engine has a tendency to die out when throttle is applied, remove, clean, and rebuild the carburetors. This is assuming you have compression and good spark on all cylinders.

(VRO Changeover Judgement Call)
(J. Reeves)

The VROs first came out in 1984 and have been upgraded quite a few times. In my opinion, back around 1988, they had perfected them but I think that they were upgraded even more since then. As long as the warning system is operating as it should, I feel quite at ease with them.

Some boaters have voiced their thoughts such as "What if that overpriced plastic horn should fail while I'm under way for some reason, and the VRO decides to fail five minutes later?" Obviously that would result in a big problem which really brings their fears into view.

The word "ease" is the key word though. If one has the slightest feeling of being ill at ease with that setup, then they should take the route they feel more at ease with. A judgement call each individual would need to make on their own.

(VRO Pump Conversion To Straight Fuel Pump)
(J. Reeves)
You can convert the VRO pump into a straight fuel pump, eliminating the oil tank and VRO pump warning system, but retain the overheat warning setup (and fuel restriction warning if so equipped) by doing the following:

1 - Cut and plug the oil line at the engine so that the oil side of the VRO pump will not draw air into its system. Trace the wires from the back of the VRO to its rubber plug (electrical plug) and disconnect it.

2 - Trace the two wires from the oil tank to the engine, disconnect those two wires, then remove them and the oil tank.

3 - Mix the 50/1 oil in the proper amount with whatever quantity fuel you have. Disconnect the fuel line at the engine. Pump the fuel primer bulb until fuel exits that hose with the tint of whatever oil you used. Reconnect the fuel hose.

That's it. If you want to test the heat warning system to ease your mind, have the key in the on position, then ground out the tan heat sensor wire that you'll find protruding from the cylinder head. The warning horn should sound off.
 
Re: Am i missing something?

thanks joe. I appreciate it. When i bought the motor i of course checked the compression of both cylinders and it was equally 140. Also the VRO system had already been converted over to use mix fuel setup by doing exactly what you mentioned above. as for the warning buzzer it was completely shattered in the control box so i got a LED red warning light instead and mounted it on my console so it would blind me if it went off. thanks for the great advise.
