The iboats forum moderators are excited to announce that at this time it appears the iboats forums posting pictures function is working once again. Though we cannot promise for how long, we're hoping for indefinitely.
Hi everyone,
Last month I posted a thread about changing the impeller on this motor, and that was no problem. After doing the impeller, I am noticing water coming from under the powerhead (see pic). I guess it was doing it before the impeller change, but the new impeller must be moving more...
Hi everyone,
I replaced the impeller, housing, etc., and all is running fine. One small issue is when I was putting the LU back on, it felt like something was obstructing the driveshaft. I pulled it back and one of these fell out and the other was sitting inside the leg perpendicular to the...
Hi everyone,
I just got a new to me 1986 Mariner 45 and I know that I need to change the impeller, etc. I have only worked on OMC stuff previously and want to cover a base before taking the LU off. I have watched a few videos online for Merc/Mariner models similar to this one, and there seems...
So I took the boat out of the garage today to fire it up in a barrel after sitting all winter. I went to hook up the battery and for some reason I reversed the connections. I know, I know, I feel like punching myself in the face.
I believe the key was in the on position. I saw a spark, and...
Hi,
This may be a silly question, but I am going to ask it anyway. I am using the OMC recommended L78 (surface gap) plugs and the motor runs just fine. I wanted to put a resistor type plug in to see if I can clear troubleshoot some interference with my depth finder. The only ones I can find...
Hi, I just took the carb apart to do the kit, and hooray, the original varnished up cork float is in there. Parts diagram says to use OMC 0375919, but iBoats does not appear to carry it. Can someone please provide the equivalent part number I can order?
I found some sites selling 0396514 as...
Hi,
My dad gave me this 1976 Johnson 2HP that I used to use on a small rowboat when I was a kid. I gotta say it has probably sat for at least 15 years, maybe 20 since last run. The bad - was put up with at least half a tank of mixed gas in it, so I want to see if this is even doable with the...
Hi,
Motor is a 1979 Evinrude 35 electric start. I just bought this boat/motor last fall, so haven't run it much, and really haven't worked on it at all. I took it out today, and it seems like the throttle lever doesn't really do much until the last 1/3 of the way forward. I can get almost...
Hi everyone,
I am going to take a look at a boat this weekend, and the seller can't tell me the year or model of the motor. I asked him to look for the welch plug, etc. and he either isn't looking for it, or can't find it. Was wondering if based on a picture anyone could give me a rough...
Hi,
This may be an easy question, but I don't want to ruin the new coils I bought, so I thought I'd ask. These are OMC coils part no. 0502881.
So the coils came in these pieces: Coil, spark plug wire, boot, and a small 'spring' looking thing that has a 90 degree bend in the wire that turns...
Hi,
Hoping for a bit of help here. Model 25R73A.
So when I let the motor sit for an extended period (a day or more) it'll fire right up on the 2nd or 3rd pull and run as long as I want it to. When I shut it down and let it sit, it might pop over for a few seconds, then shut down, and no...
Hi,
I was looking at the wires under the cowl the other day, and the ones that run to the kill switch are fairly bad with copper exposed. The kill switch itself is missing the button, so I have never used it. I am afraid that with the frayed wires that I may get an unintentional short. Is...
Hi everyone. Just wondering if anyone has an idea of what to look for before tearing the LU back off.
I bought this motor last year and figured it was due for an impeller change this winter. So we took off the LU and replaced the impeller and water tube grommet and put everything back...
Hi everyone,
So I was replacing the impeller and the crankshaft seal on my '72 Johnson 25HP last weekend, and when I took off the plate for the access for the shift rod linkage, the paper gasket fell apart. I have an old '62 28HP Seahorse parts motor in the garage, so I took the gasket off...
Hi everyone,
When I changed out my lower unit oil last fall, I noticed some water intrusion in it, very milky even after not running for about a month. When I changed it the previous time, I put new seals on the filling screws, so I don't think that is the culprit.
So I wanted to do the...
Hi, I just want to make sure I am doing this right and didn't miss anything. Should be a fairly simple one.
I bought a new prop for my motor and it arrived yesterday. I removed the old prop and cleaned off the shaft. I slid the new prop on, making sure the shear pin was lined up and the prop...
Hi all. I am getting to my wits end trying to figure out how this linkage works. It is the one pictured below that is just hanging there. Right now I have it rigged together with a piece of wire, but I really want it back in optimum working order. From the picture, can anyone tell me which...
Hi,
I broke a part on my carb linkage on my 73 Johnson 25HP and cannot find it anywhere on the parts diagram. It is this little plastic bracket I have circled in the pic below (which I found in another user's thread). Any ideas?
