    Basic fuel questions

    Wow, that was quick. Thank you Scott Danforth and Sea Rider. Here's present the situation: 1.) I just took apart and cleaned the carb 2.) Inline bulb is pumped, I can hear fuel fill the empty bowl and then stop. 3.) I pull out choke knob. And pull start cord. 4.) Engine runs briefly then slows...

    Basic fuel questions

    I have three basic questions re. simple 2 cycle small hp outboard troubleshooting. I know the answers should be obvious, but maybe my understanding is incorrect, so I just want you to make sure I'm not assuming something wrongly: 1.) If a fuel feed problem is due to the fuel pump not supplying...

    1986 Mariner 8hp 6G1 won't idle without choke

    I just cleaned up my low hours 1986 Mariner 8hp 6G1 manual shift (Yamaha block, I believe) after 30 years of storage. Taking off the scratched cowl, the engine looks new inside. I replaced the waterpump (though the impeller actually looked good). I took off the carb, cleaned it -- all parts...

    How to set WOT timing without test wheel?

    I've read two alternate "non test-wheel" methods for setting WOT timing on the Johnson/Evinrude forum incl. "The Joe Reeves" method. Is there something similar for Mercury/Mariner engines of my type? (Mine is a 1989 Mariner 25hp EL two stroke. I have the Mariner OEM manual for that year, and...

    Loctite propshaft seals or not? And what is Loctite type "A"?

    Just got the real OEM manual for my '89 Mariner 25hp EL 2 stroke and it seems to say apply Loctite type "A" onto the new prop shaft seals' OD's when pressing into the lower unit. Is this absolutely necessary, and what is Loctite type "A" anyway? I have Loctite red, Loctite blue and Loctite 680...

    '89 Mariner 25hp EL -- two prop shaft seals or one???

    I have an '89 Mariner 25 hp EL, and I'm replacing the prop seal(s). When I opened the lower unit up there were two separate prop shaft seals -- an inner and an outer. I have as replacement a genuine Quicksilver 26-85090A1 kit. But in the kit there is only a single prop shaft seal. This seal...

    Mariner/Merc CDI Electronics coil problems/confusion

    (My motor serial # 0C154840) I have an '89 Mariner 25 hp EL with CDI ignition, and it takes the standard two 7370A13, 832757A4 type coils. One of originals on the motor is bad. So I sent for a replacement, and what arrived was a CDI Electronics part #184001. I put the new coil in the engine...

    '89 Mariner 25hp - what is the carb float setting?

    Nope, I was wrong above. I misinterpreted the drawing in the manual. What it actually shows is a 1" measurement from the top of the float to the bottom of the main jet post. Here, let me attach the drawing so that's easier to understand:

    '89 Mariner 25hp - what is the carb float setting?

    Hi Ihave a n '89 Mariner 25hp EL with a WMA 32 carb that I'm re-building. What should I set the carb float height to? Also, just checking, re. the fuel pump on the carb -- diagrams and videos I've seen show a single unit for the diaphragm and gasket. My kit came as separate diaphragm and...

    1989 Mariner 25hp EL question about choke solenoid

    The choke solenoid on my '89 Mariner 25hp # 0C154840 is shot. I'd like to start this motor in a tank to see if it is runnable at all before spending $80 for that part. The motor also has an adjustable manual choke. The solenoid opens or closes a very small port to air on top of the carburetor...

    1989 Mariner 25hp DIY rubber cowl seal?

    The rubber cowl seal is falling apart on my '89 Mariner 25hp. I looked up the price of a replacement and promptly passed out. When I came to, I thought for a bit and then wondered if anyone else here had come up with an alternative seal. I notice some extruded rubber seal material is sold by...

    Stator and Trigger test on 86' 35 hp Merc?

    Here -- hope this photo clarifies the following: Trace the wire bundles from the rotor and trigger to the switch box. Lift the necessary wires off of the box and separate them at the connectors there. \ Then test the trigger side of those wires and the rotor side of those wires. Use a bolt...

    Which engine-side fuel fitting for a 1989 Mariner 25hp 0Cxxxxx serial

    I bought an Atwood fuel hose fitting advertised for "Mercury/Mariner" today at the local Runnings store, and it's not right. While it looks rught and fits in place, the catch doesn't engage in the slot on the positioning peg, so there's nothing to retain the hose fitting in place. Returned...

    1989 25HP Mariner -- how does the ignition trigger work?

    Thanks faztbullet! I was thinking it was something like that, because as i moved the bolt around the hub there was a momentary change at the split. Hmmmm. now things are getting confusing again. If that split is a trigger firing spot (which seems logical) then why is it in a very different...

    1989 25HP Mariner -- how does the ignition trigger work?

    Here's what I get for magnet locations from the first photo. 0.199" from the flywheel bolt hole location, measured along the inside face of the rim. And that should be 40 degrees from the center of the keyway.

    1989 25HP Mariner -- how does the ignition trigger work?

    I'm in Vermont, flyingscott. I have found two photographs of magnet positions from the same year (1989) 25hp Mariner/Mercs. They seem to agree fairly closely (though not exactly) about magnet positions relative to the keyway and the flywheel ring gear bolt positions. I was going to use these as...

    1989 25HP Mariner -- how does the ignition trigger work?

    Thanks flyingscott, I appreciate your help. This is why I'm confused: This is the inner hub - actually it is magnetic, it can hold a bolt pretty strongly upright Also it has a polished SS inner surface. Behind that, maybe you can see what might be a circular ceramic magnet. Then the rusty cast...

    1989 25HP Mariner -- how does the ignition trigger work?

    What does the ignition trigger head read? I know it doesn't read the outer flywheel magnets. It faces inwards. So it must be reading something on the inner (shiny) part of the hub -- my question is: does anybody know what is in that band -- some kind of embedded magnetic spot (or spots) for the...

    1989 25hp Mariner flywheel bolt hole stripped when pulling -- suggestions?

    One of the two bolt holes in the flywheel of my 25hp Mariner stripped when I tightened the puller while I was trying to remove the flywheel. Any suggestions for getting the flywheel off, now? I may be able to get a nut under that particular hole, but it's pretty tight to work in there. I'm...
