Re: 1979 Mercury 40 HP

I think you are talking about the remote controls?<br /><br />The lever you are talking about is the fast idle lever and should only be used when starting. After that just use the main lever. It sounds like a Quicksilver control unit (which is also covered in the manual).<br /><br />Talking of manuals, I cannot recommend highly enough the proper service manual. Although it assumes a bit of knowledge on the part of the reader but when you read them with the seloc or clymer manuals it helps a lot!<br /><br />Great news that you got the engine running and that the water pump wasn't the nightmare you thought it might be. I suspect that engine will go on to give you many many years of great service!<br /><br />congrats and all the best!

So you are suggesting the Factory Service manual, as well as a 3rd party manual (seloc, clymer)?<br /><br />Thanks again for all the help.<br /><br />-TheChad

Re: 1979 Mercury 40 HP

yes: I'd definitely recommend the two manuals: factory plus a third party one.<br /><br />No probs about the help: it's what iboats is all about: maybe you'll be able to answer one of my problems one day.....

Re: 1979 Mercury 40 HP

When I was putting the lower unit back in, there was a plastic bushing, and a rubber bishing that fit on the splined shaft.<br /><br />They fell out when i took the lower unit off. I just want to double check and make sure I put them back on correctly..<br /><br />I put the plastic bushing on first, then the rubber bushing on top of that, then put the lower unit back in.<br /><br />Can anyone confirm that is correct, or incorrect?<br /><br />Thanks.<br /><br />-TheChad

Also, Is there a way to check if the timing is correct with out any special tools? or will i need to take it in to see if it is correct?<br /><br />Thanks,<br /><br />-TheChad

Re: 1979 Mercury 40 HP

go to your local auto parts store and get a cheepo inductive timing light, about 12 buck$<br /><br />attach it to #1 plug wire and start motor. pull trigger, aim at flywheel. works best when its dark out, so you can read the timing.<br /><br />that motor is sooooo much eaiser to work on than you could possibly imagine. i have one, but its 2 years newer. dont get nervous, you can do it man!

Does anyone have a suggestion for a prop? (Brand/Place to buy/type/etc)<br /><br />The prop that is comming off the engine (Damaged) is a 10-3/8 x 13 Mercury Aluminum prop.. Probably the one that came with the engine.<br /><br />Thanks again,<br /><br />-TheChad

One more question about the 'remote' controlls...<br /><br />What does the knob in the front of the controll box do? I didn't want to turn it untill i knew what it did.<br /><br />Thanks.<br /><br />-TheChad

Re: 1979 Mercury 40 HP

It should adjust the friction (tightness) of the throttle lever.

Where's the oil come from? Fuel? Or is there a place I am suppose to put oil?<br /><br />Thanks,<br /><br />-TheChad

Well my previous post was I guess too early stated.<br /><br />While we are putting new floors in and re-wiring the electrical (Lights), I have not run the engine. <br /><br />Today I went to start it up, just to keep it running, and make sure its still running, and it's back to the same 'ol crap it was doing before..<br /><br />It starts, runs for about 15-30 seconds. Than dies. If i spray Carb cleaner into the carb, it will keep running, so as long as i have carb cleaner.<br /><br />So basically its still acting as though its not getting fuel. The fuel screen is clean, and as you know there is a new fuel pump diaphram, so i don't understand why it wont run...<br /><br />What else is there that could be causing this?<br /><br />Do those check valves have anything to do with this situation? In other words, should i replace them?<br /><br />Thanks again,<br /><br />-TheChad
