Re: My Mariner 60 is tempermental

yes he did it in the driveway on the muffs he said he followed directions from a manual he bought said he left it in my garage for me but i havent seen one around ill look when I get in. said it was easy said resistentcy test or somthing like that it was my number 3 cylinder not working due to switchbox

Bass is in a link in post further up

Re: My Mariner 60 is tempermental

ok I hope I get this right he said he did it like this: said I wasnt getting spark on the number three cylinder(he said on mine it was when he heated the switchbox) didnt pass spark test so he said stator should be good because the other two were getting spark.so it could be coil trigger stator or switchbox. he did resitance test on stator and trigger coil said you will need book to know the numbers for the results. said they were good that left the switchbox. said he used a dva multimeter hope this helps tryed to get him to log on to here but he is busy he is super smart and could explain things better


P.S. he said follow the manual closely because you can fry good parts in there if your not careful said manual will have numbers and step by step instructions . Guys I trust my brother but i know you dont know me so feel free to run this by anyone else here wont hurt my feelings at all. good luck

He says electrical is funny thing wiil act one way one day and another way another day but will soon fail

Re: My Mariner 60 is tempermental

OnTheWaterNow- Thanks for the tips from your brother. Great advice. I checked out your brother's bass picture. That's one hellofa fish! You boat looks pretty sweet too. It's so.... well.... clean. My flat bottom would certainly win the ugly award, but it get's the job done. Caught a nice 26" northern this morning and it's about to hit the fry pan!

Re: My Mariner 60 is tempermental

yah I too noted how clean your boat is. Lucky you. My little 14' fiberglass is rotted and a mess. Ill have to restore soon. anyway. So yah I did folow the book, and like I said I found tests and numbers for all the electrical except the switchbox, Maybe its because its a Seloc manual? anyway. one major thing I found last night, was that my timing was advaced to like 33? I didnt know since my flywheel was on wrong. zeroed the flywheel and marker, and now retarded the timing back to 25?(2?<27? recommended WOT 5500). That would explain all the unburned fuel and fouled plugs. so check your timing.

Re: My Mariner 60 is tempermental

I was reading this forum, (twice) and had to go check to see which one of you had stolen my motor. I too have the same exact problem but with a twist. When my motor (88 model) decides to do it's thing there seems to be a noise coming from under the couling as if something is rubbing. No for the life of me I have not found anything that looks loose. I too was blessed with the wire rot, and went to great pains to take the ends off the trigger assembly and slide heat shrink tubing on all of them. Maybe if there is a shorting together of the wires the trigger jumps around I don't know. That's the reason I'm here. Runs real good just like yours, then all of a sudden bog bog, or bog bog and then here we go with no more problems until the nexy time. Go figure. I have the manual and will try and do a swith box test first. I do do know though from looking at the plugs that all are not firing the same. Thanks for listening. Any any help would be appreciated. I'm not afraid to tackle any motor at all but the electronics whip me.

Re: My Mariner 60 is tempermental

well, larry check your timing its probably off. I finally got my timing set last night! can you believe it was off by almost 10? and still ran? @ cranking I got the normal 3? then moved to max throttle and it read 33?.

So if my engine calls for 27? at full throttle(5500rpm), I should set it at 23? for static timing (not running) right?

That would also explain my foul pugs right?

Re: My Mariner 60 is tempermental

Timing very well could be a factor your right, can you tell me what type light you used. I have the old type that goes on the plug and I tried several months ago to check mine but it wouldn't work. I understand the static timing but need to find a light that will work. Thanks.

Re: My Mariner 60 is tempermental

I just picked up this $16 light at Harbor Freight.

if your light dosnt work, either its broke, or your not getting a signal through your spark plug wire. So you might also want to get a spark plug tester and test all cylinders.

$1.99 @ harbor freight.

Re: My Mariner 60 is tempermental

Thanks for the light info. That's what I was talking about. I didn't know if you used the induction type or the old direct connect type that used a spring between the plug and wire. That's what I tried and it wouldn't work so well. Not strong enough fire or something I suppose. Have access to a good Snap-on. will try that soon. Still leaning toward switch box though. Just curious---I read on this post about the regular gap plugs. I am running the surface type, seem to do ok, but was wondering if anyone used the regular and if so what brand and plug #. I know the depth has to be right or real problems can happen. Thanks

Re: My Mariner 60 is tempermental

Hey guys I found that manual my brother left for me there is a section in it that says switchbox bias to test switchbox ill scan it and post it . westtexas I see you sovled your problem congrats man

 

[westexasrepublic]

Re: My Mariner 60 is tempermental

well not really, I just found another reason I have a problem. havnt lake tested yet. But im sure it will help the overall performance once I do fix the problem of the bog....bog...bog bog.....

But what manual do you have? and if its Seloc can you tell me what page cuz thats the one I have.

 

[OnTheWaterNow]

Re: My Mariner 60 is tempermental

yes seloc ill look now

 

[OnTheWaterNow]

Re: My Mariner 60 is tempermental

section 5 page 28 switchbox bias bet that is your problem if coil stator and trigger is good

 

[OnTheWaterNow]

Re: My Mariner 60 is tempermental

looks like that test is for motor with two boxes sorry

 

[OnTheWaterNow]

Re: My Mariner 60 is tempermental

ok its page 5-27-5-28 for single box. let me know whats up if you get anywhere

Timing seems to be critical. I just found a goofy hand written note on the back of the original warranty card that I found a couple of months ago. It says "crank WOT 20deg". So what the heck, I changed mine and in the barrell it seems like it might have done the trick. I'm taking it out for a spin tomorrow morning and I'll let you know.

As for timming lights, don't scrimp, get the brightest one you can find and if you can, get a variable one so you can set the advance at the light and only worry about keeping the "0" on the mark. It's 100% more accurate that way. If it's not in the budget, you'll need to get the engine inside a garage out of direct sunlight. I once used a toliet paper box I found at the ramp and made a hood over the engine. I think it was rather fitting actually.

Re: My Mariner 60 is tempermental

West texas-----I meant to ask about your procedure for the static timing. Did you remove the plugs for easier and more cranking rpm and if so what did you do or how did you get # 1 to fire so timing light would work. Just a thought.
Thanks

Yes, the manual calls for removing the plugs, placing the plugs back on the plug wires and grounding the body (threaded end) of the plug. Ungrounded, you would'nt have a complete circuit so no current flow or spark. There are also some warnings that failing do ground all the plugs could damage the switch box. I'm not 100% sure of that because that would mean that a fouled plug could damage a switch box. It's in my Seloc manual and I'm not all that interested in disproving it.

I fashioned up some old 8 guage wire with large wire clips and clipped them to each plug and to a known ground point on the block. I used and inductive timing light on the #1 plug wire.

One note: If you use an inductive timing light make sure you place the pickup far enough away from the other plug wires and the block so you don't accidently pick up the spark from another cylinder. If your timing mark is erratic this is likely what's happening.

Re: My Mariner 60 is tempermental

my 79' Mariner 70 hp 3 cylinder is a "Type V system" Seloc pg 5-47

its says quote "The switch box and ignition coils cannot be thoroughly checked with conventional test equipment. A quicksilver thunderbolt ignition analyzer is required to properly check these items."

so I dont know if thats true or not, but that is all it mentions about testing a switchbox.

as for setting the timing, I just followed the manual. and watched this video for assistance click here. http://www.themarinedoctor.com/videos/statictiming.wmv
