    1990 mercury 8hp piston ring locating pin

    Hello, I obtained a non running 1990 mercury 8hp. The compression is really low, 40psi. After inspecting the gaskets and finding no real cause for low compression, I decided to crack it open to inspect further. There is very minor scouring (not enough to feel withy finger nails) and all in...

    DVA stator testing

    Yup, that was it. Rebuilt the fuel pump and now shes running soooooo much better. Thank you everybody for your help!!!!

    DVA stator testing

    I think I found my problem, fuel starvation. I pulled my fuel pump today and found this. On my way to the marina to pickup a rebuild kit. I'll keep you posted

    DVA stator testing

    I did look inside and can see carbon on the #2, doesnt look much different then the other pistons. #3 looks fouled like that after idling for a few minutes. I did another ohm test this morning while the engine was cold, I'm getting 3560 from red to blue when specs say it should be 3600-4200...

    DVA stator testing

    I swapped #2 and #3 coil, there was no change in the fouling of the plugs. I got the motor warmed up to allow me to let it idle and threw the timing light back on. It is showing 3 degrees at 700 rpm. Not looking like the coil or the timing.

    DVA stator testing

    I got the timing light hooked up and at about 1500 rpms it's at almost 20 degrees. The manual says it should be 0-4 at 650 - 700 rpms. Does this mean my timing is way off? Afterwards I pulled my plugs to see how they looked and the bottom was all fouled only after a few minutes of running...

    DVA stator testing

    I was getting started on indexing the flywheel. When I pulled the brand new plugs out, I noticed the top had minor oil on it, the middle was clean and had the smell of gas, but the bottom was black. I'm wondering if there is an issue with spark because, in my above videos showing the spark...

    DVA stator testing

    The high idle is because I have to give it some throttle to keep running. I cant put it in gear when I have the throttle at that point. if I pull the throttle back all the way to a normal idle, it will spudder and die from the popping. After a few minutes of it warming up I can let it finally...

    DVA stator testing

    I uploaded some video showing a 7/16" spark gap test for each cylinder. To me it looks like the bottom might be missing, but you can hear it so I'm thinking it maybe a weaker spark then the others. Gap test top https://youtube.com/shorts/_W087smBtqU?feature=share Gap test middle...

    DVA stator testing

    Thank you for the input. I replaced the switch box yesterday as it was the cheapest and easiest to get to. I pulled the coils today and examined them, they look to be in good condition. I'm ok with spending the money to replace the stator and trigger since I'm in there. I just have a hard...

    DVA stator testing

    Here is a video if the motor running. Ive done a compression check, I have pulled the carbs, cleaned and adjusted. Replaced fuel filters, installed temporary clear fuel line in front of carbs to check for air bubbles, replaced fuel with fresh fuel, replaced spark plugs, tested ignition...

    Which stator to buy

    I'm in the market for a new stator and am finding multiple options. I'm not rich so I am going to pass up spending over $400 on oem. In the aftermarket lineup, I'm finding a jetunit and cdi stator at a lower price, but different setup for the wires. Below are photos of what I'm looking at...

    DVA stator testing

    Hello iboats friends. On idle, I have a misfire occuring pretty regularly. I ohmed out the ignition system and everything comes up good there. When I do a DVA test on the stator high speed while engine is running, the reading is unstable and bouncing around, but above the 20+vdc . When I do...

    Help identifying star replacement

    On the part 398-832075a5 they have 4 wires (2 yellow, 1 green, 1 white) whereas the one on my motor has 5 wires (2 yellow, 1 red, 1 blue, 1 black) and I see on the oem version, there is an adapter included 834949a3. Essentially, could I get an aftermarket and buy this adapter to fit an...
