1975 johnson 135. Trying to get the lower unit off to replace the impeller. I have a manual and I'm following it. I completely disconnected the shift linkage so that should not be a problem. Removed the 4 bolts holding the lower unit on as well as the trim bolt and the other bolt in the...
1975 Johnny 135 with remote control. Recently it has been very difficult to shift into reverse or forward. I hear a grinding noise at the motor and feel it at the handle of the remote control. If you give it lots of throttle, it will grind horribly and not move. I managed to get back to the...
I normally used the UL-77V gapless plugs in my 1975 135, But I was in Wallyworld the other day I saw some marine plugs on CHEAP sale ($1.50 each). Guys were swarming around and because the number looked close the numbers I am familiar to, I went ahead a bought four of them.<br /><br />They are...
Sometime in the next couple of weeks I'm going to tear into replacing the water pump. I bought a repair kit and I have an ancient (circa 1974) origional OMC service manual for the 1975 135 HP model. I've also been searching for posts about water pump replacement, but I was interested in anyone...
Antbody use a homemade method to sipe the tires on your tow vehicle for better traction at the ramp? Most of the stuff I see on the net says to use a hot knife, but a utility knife with the blade cut down supposedly works as well. <br /><br />Cuts to be 1/4 inch deep on new tires, 1/4 inch...
Decided to do some repair on my worn out 30 yr old swim ladder. This boat has seen better days, so my main goal is to keep it running and not worry so much about how it looks.<br /><br />Swim ladder has broken brackets, worn out rubber at the hinged section, and completely missing any type of...
1975 Johnson 135. Carbs and waterpump rebult 2 years ago. Gas tank cleaned out this year. Compression 125-135 in all cylinders. Looks to be mostly origional except new starter. <br />Engine runs great for 1st 5 minutes than power drops considerably. Determined that it had weak spark in #1...
Got a boat from my father in law two months ago. Not a boater, but learning fast. I have fought this boat almost every weekend:runs horrible, wife smashes it into the dock, etc...<br /><br />Take it out last weekend. After adding 15 gal of gas at the local station, I notice a refreshing...
1975 Johnson 135 w/ TNT. I get it out on the water at WOT and trim the engine up, only to notice a couple of minutes later that it has dropped down a little. The trim gauge does not work, but I know it's dropping down. While trailering I let it rest on the "trailering bar". Parked at home I...
1975 Johnson 135 w/ tilt trim. I get it out on the water at WOT and trim the engine up, only to notice a couple of minutes later that it has dropped down a little. The trim gauge does not work, but I know it's dropping down. When I park it at home I trim it all the way down and I see no...
1975 135hp Johnson<br /><br />Well.. I shoulden't say homemade, but I have a nice mechanical oil pressure gauge (automotive) that is not getting used. I have seen in other posts about newer engines that have pressure gauges and wondered if adapting a oil pressure gauge to an old outboard would...
My recently aquired 1975 Marlin has seen better days. I have seen lots of other posts about how to wet sand/scotchbrite with comet/polish/wax to get the finish back, but I'm not sure this boat is worth the expense or effort. <br /><br />I would like to at least clean it up and try to keep the...
After checking the filter "screen" on my 1975 135 Johnson after the engine was not running well, I decided to add an automotive high flow filter to the fuel line. Any issues I should be worried about? The engine ran great after adding the filter and tweaking other issues in the engine, so I do...
I have a 1975 Johnson 135 with power trim/tilt. I am having issues with it not starting and tilt/trim not working at the same time, and it seems like buzzing trim and clicking start solenoid are comming from the same solenoid. Are they integrated, or does the trim just pick up positive from...
Howdy. I'km new to the boating world, but good with mechanical things.<br /><br />I just aquired a 1975 17 1/2 ft Marlin with a Johnson 135hp power trim outboard from my father-in-law. He cleaned out the gas tank before giving it to me. Last he ran it was 2 yrs ago after a carb tune up, and it...
