    Mercury 9.9 not peeing (but impeller tested good)

    I have a 90's Mercury 9.9 that stopped peeing reliably (would sometimes). I started getting steam out of the weep hole. I pulled the lower unit off to check the impeller and flush it out. Our lake is pretty mucky so I figured some junk got sucked in. Pulled it apart and the impeller is perfect...

    New to me Mercury 9.9hp Outboard - bunch of questions

    I made the move away from a very problematic Johnson 8hp to a good running Mercury 9.9. I mounted it to today, hooked up the fuel and was able to fire it up without any real issues. Idle great in neutral and headed out into the lake to open it up. Backed out in reverse no issue. Put it in gear...

    Johnson 8hp STILL not right, but someone offered a new idea I want to run by y'all

    1990 Johnson 8hp J8RESR Here is the backstory if you care to read: http://www.marineengine.com/boat-forum/showthread.php?448303-90-8hp-Johnson-idles-but-no-wide-open-throttle I've basically done everything to this motor, but it's still not right. I was going to break down and take it to a...

    8hp '90 Johnson carb flooding after multiple rebuilds

    1990 Johnson 8hp J8RESR here is the more complete backstory in one of my previous posts: http://www.marineengine.com/boat-forum/showthread.php?448303-90-8hp-Johnson-idles-but-no-wide-open-throttle I have rebuilt this carb at least 3 times and also had a couple of guys that are pretty solid...

    '90 8hp Johnson idles but no wide open throttle

    I have posted threads related to this issue on other forums and gotten some good advice, but have not been able to track down this issue yet. I need a fresh set of eyes on it. Frankly, I'm at the end of my rope with this thing. I'm going to write a novella here, so sorry for the length, but...

    8hp Johnson bad stumble under load / WOT

    I was having all kinds of issues with the motor, but have since had a buddy with at least some decent know-how go through it. He rebuilt the carb (again), replaced the impeller, fixed the cam roller and pull start spring. The engine starts nicely and idles nicely, finally. In neutral, it'll...

    8hp carb flooding and pouring fuel out

    I had the motor attended to by some outboard guys. It wasn't idling or throttling correctly. They took the carb apart and found a missing clip/spring part that was causing the carb to flood out. Got the parts and they put it all back together and got it running right. I brought it home tonight...

    1990 Johnson 8hp running but low power/speed no real WOT

    I got the motor running and idling (not perfectly), but it's sorely lacking giddyup. When I first got it, it hauled tail on my little Jon Boat. At WOT, it's just got no real power. Feels very bogged down. How should I attack this? - compression test - timing tune up (can someone send me a link...

    1990 8hp Johnson won't idle/stay running

    I was sure I posted this last night, but I don't see it. Sorry if it duplicates. I have a 1990 8hp Johnson that ran fine a couple of years ago, then started acting up (surging, hard start, bad idle) and then it sat since then. I decided to get it back on the water. The motor will kick over...

    1990 8hp Johnson won't idle/stay running

    motor used to work fine and run well. It started not running great (surging, poor idle) and then it has gone unused since. I decide it was time to get the boat back on the water, so I pulled the motor off and have it hanging it a 50 gallon drum. I can get it to kick over (especially with a shot...
