On a boat project I inherited with a Mercury 40hp, I discovered that the tilt switch on the motor works the opposite of what I believe it should.
Specifically, pressing the rocker to the side labelled "Down" causes the motor to tilt up, and vice versa.
It appears that at some point a previous...
I got the on/off switch figured out. It's difficult to move to the off position without the lanyard key installed but a paper clip worked...now seems easy.
Next is to confirm the wiring and I've had no luck finding a service manual either online or to buy.
Everything I've found is for 1998 and...
Thanks.
I am beginning to think the remote isn't standard on this one either. I can't move the on/off switch to the off position - there's no clearance between the toggle switch and the cover over the switch.
At some point I'll likely remove the remote to see if I can figure out why. At present...
Thanks. I still have a way to go before I can even turn it over to check compression. The wiring is another challenge, apparently a prior owner didn't like wiring, and much detail I find online for the throttle control doesn't match what I'm looking at for what is supposed to be the kill switch.
The photos show the motor as received.
I was next going to ask about oil injection since I believe the ELPTO indicates oil injected.
No clue what previous owners may have done. I also noticed some disconnected wires. Now that I've got the model details, got the manual I hope I can determine if...
I will, at least twice. The manual will be easier to find now without the bad information found earlier.
I also have an experienced mechanic that's going to do a sanity check before trying to run it.
That makes sense, thank you!
That also explains why I had difficulty finding reference material.
The reference to 4 stroke came from a online source, but now I see it is two stroke.
I've not tried to run it and won't until I'm confident and know more.
In short, I can't figure out how to check or change the oil and filter - can't find anything on the motor or online.
I'm amazed at the collective wealth of information and those will to help on this forum, so thought I'd try.
I have a 1995 Mercury 40HP, 4 cylinder, 4 stroke model "1040412RT...
