On an 87 Johnson GT150...where do I install the water psi gauge?? Do I tee into the tell tale?? Or is there a place in the water jacket to install?? Hoping not to have to drill and tap. Thanks alot!!
1987 Johnson GT150. I was out on the lake a few weeks ago....and the tach just quit...no erratic behavior...just quit dead. It has juice...you turn key on and it zeros. I installed new tach last night...still nothing. I also installed a volt meter last night while replacing the rest of my...
I have read somewhere on here about the loading up on the 80's and 90's merc v-6's was caused many times by bypass valves in the oil injection. I'm fixing to do the carbs on my friends black max and was wondering about these...I would like to clean them. Where are they located?? What is the...
Fixing to rebuild carbs on a friends black max... ser#b962754...88 model...150. It has champions in it now...and I know mercs like NGK's. What plug are you guys running and have you changed plug heat ranges for any reason? He idles around alot and it tends to load up...I know thats not a...

I have an 87 Ranger 373V bass masters classic edition...she is in perfect shape...never seen one from this vintage look so nice. My question is it has a GT150 on it and has the hidden control box. So it doesn't have the friction screw to tighten the throttle so it doesn't decellerate when I...
I have read all the posts and just want to make for sure before I do this tommorrow that it will work. I have read your post about what to do and have looked at mine and think it will work. Will your process work on the 87 GT150?? Want to premix...this engine is ALL original...the head bolts...
Do not want to use the seloc or clymer...I want to find an OEM maual...I ordered from Kencook.com for my johnnyrude stuff. Would rather not go through a dealer...anyone know of a place to get one online? Or maybe have one you would like to sell?? Thanks alot!! 1989 Mariner MagII 150hp :D
Okay helping a friend with his new boat..tach does not work.. I had a sahara sitting around I knew worked so we hooked it up and nothing. The gauge DOES have power...it zeros out when you turn the key on...just nothing from the engine...start it and still sets at zero. The engine was recently...

Just wondering if any of you johnnyrude folks knew anyone that had a good 20" 140 looper they wanted to get rid of. I'd really like to move up to the looper from the crossflow. The pic of my ranger is with a 78 140 crossflow on it. Love the engine but would like to find an 80's or 90's...
Checking out a boat for a friend of mine and was wondering on what the going price was on a 97 150 intruder. Rebuilt by an authorized evinrude dealership one year ago due to trash in carb ruining one cylinder. They went ahead and rebuilt the rest of the powerhead. In fact it is still in the...
Just finished my electronics on my 78 johnson 140...everything new from CDI. Only problem is my cover won't fit right now...the brackets hit right between the coil wire boot and coil....it will go down but then the left side won't latch. Anyone else run into this when going with the CDI coils...
Wanting to get a opinion/info/experiences thread started. I have a crossflow 140 I love it. I think it was in 86 that manufacturers started rating on the prop instead of engine?? As in autos I'm sure the drivetrain will eat up 15 or so hp. What if anything can you do to bump up old...
I'm fixing to rebuild my waterpump and replace the inlet screen on my 78 johnson 140. I have the service manual and have looked and looked and can't see what holds the inlet screen in. I'm sure I will see it when I get in there, but it would be nice to know before I tear into it later this...
