It is a 3 blade prop and the...

    "decarbing"?

    I have read on here a lot of people advising on decarbing but I do not quite understand what that is or how to go about doing it. My motor is a 75 Johnson 135 horse if it is motor specific. Thanks in advance for any advice.

    Would this be a good parts motor for me?

    I have a '75 Johnson 135 horse motor. I was trolling thru Craig's list and found a '72 Johnson 100 horse. They are both v-4 and from what I understand most of the parts should be the same or am I mistaken about that. If anyone can tell me if most of the parts should b interchangeable I'll pick...

    Can I edit my thread title??

    I started a thread when brand new to the site and titled it poorly. I would like to edit the title so people know what it's about and would prefer to not start a new duplicate thread. Is this something I can do and if so how.

    Johnson 135 horse prop help

    I have a 1975 Johnson 135 horse motor and I am thinking about getting a new prop for it. The p/o told me they put on a 15p prop for a better hole shot while towing. It is a 3 blade steel prop. The boat is a 1969 18' Larson deep v hull. I have no clue what direction to go as far as a new prop...

    How do I add a tach to my 75 Johnny 135?

    I have a 75 Johnson 135 horse motor with no tach. There was a tach in the boat when I bought it but it was not hooked up don't know if it ever was. The p/o had a bunch of gauges in it that they said were put in to look cool. I really want to put a tach in but have no idea how to hook one up. Can...

    Winch strap "stretching"

    I recently bought a boat and both times I've taken it out after I get it back on the trailer I winch it up tight but it pulls back. I don't think the strap is actually stretching I'm pretty sure that when I wind it up it's not winding tightly and than as I go it's getting tighter on the drum...

    Anyone know where to find Johnson test wheels?

    I am looking for a test wheel for my 75 Johnson 135 hp motor. The service manual says its part #386246. I'm trying to set the timing on the motor and the manual says the motor needs to be run at 43-4600 rpm to do it and I really don't want to do that in the tank. Seems like a dumb idea.

    What grade gas to run in '78 Johnson 135hp

    I recently bought a boat with a 1975 Johnson 135 horse power motor and I was just wondering what type of gas I should be running. Regular premium should I be running additives like octain boost. May be dumb questions but I'm a noobie. I appreciate and advice I can get. Thanks all.

    1975 Johnson 135 "hood latches"

    I just bought a 1975 Johnson 135 hp motor that seems to be in great shape. The only real problem I have found with it appears to be that it looks like it should have a third latch to hold down the top cover in the front that is missing. Can that be replaced and if so where would I go about...

    Am I good to tow?

    I just bought a 69 Larson 18' boat with a 135 horse Johnson without power tilt. The motor has tilt lock where I can pull it all the way up and it will hold in that almost 90 degree position. It also has a prop where if you pull the motor up about half way you can flip the pop down and set the...
