    1977 150 Trim Assembly Removal??

    On a 1977 150 HP Johnson, is it possible to remove the trim and tilt assembly without removing the entire motor from the boat? I have a manual that seems to be telling me it won't come out in the usual way (from the front of the motor). Anyone have experience with this? I'm trying to get started...

    Frozen Water Tube

    I have a 1988 9.9 Sail Drive Evinrude. I am replacing the swivel tube and consequently removed the powerhead. I forced the engine block from the midsection and broke the water tube out of the exhaust extension housing by accident (there were a lot of mosquitoes). The tube is OK. I have a new...

    Leaking fuel when motor is tilted

    I have a 1977 Johnson 150 and noticed that a lot of fuel leaks from the carburetors when it is raised to the tilted position. It pools in the bottom of the lower cowling and then is released when the motor is lowered, creating an oil slick at the landing. It has always done this and the carbs...

    How do you set the air gap on the stator plate of a 1990 Johnson 30? I am installing a CDI power pack relocation kit and part of the process involves swapping some components there. Thanks!

    Guess I'm Dumb

    Where does the power pack mount on a cdi 113-4489 relocation? I have an aluminum bracket and it really doesn't seem to line up with any bolt holes. And there's no picture - ha. It's a 30 HP 1991 Johnson that used to have th ecoil under the flywheel. Rob

    Johnson 30 Horse Ignition Problem

    I have a 1990 30 HP Johnson that has very little power and a poor idle. I checked the plugs and the bottom one is normal while the top was oily and wet. After using a spark gap tester at 1/2" the top sparks only occasionally while the bottom is consistent,healthy, and blue. Any ideas?

    Weird Idle/Bouncing Tach

    OK, I have a 79 150 Johnson. It has been running well after a recent (6 trips ago) carb rebuild. I went out today and noticed the tach oscillating back and forth on the way out. For example if it was running at 4000 it would bounce quickly from 3500 to 4500. When I got to the honey hole, and...

    150 Evinrude Carb Swap

    I recently swapped carburetors on my 1979 Evinrude 150 to change over to the primer type starting system. I also upgraded from the stock 1" carbs to 1 1/4". Motor has been link and synced. Starting is now instantaneous and the low, mid and top end power has increased dramatically. RPMs up by 400...

    Who thinks this is normal?

    Replaced water pump on my 150 crossflow. There's a lot of water pressure pushing out of the upper lower unit area closest to the transom. Is it supposed to be like this? Note the stream going toward the transom and stream from the downward facing drains.

    BRP Water Pump Impeller Slack

    I installed a BRP water pump kit on my 150 crossflow today. I noticed there was some rotational play in the impeller after installing the plastic key. Is this normal? Is it possible to install the impeller upside down or is it tapered for the key to only fit in the proper direction? Thanks...
