    Sludge from exhaust/tailpipe on '72 Johnson 100hp

    Hey everyone, yesterday I got my boat running for the first time this year. This morning I came outside and looked at it and I noticed a decent sized spot where it appears oil and/or other sludge drained out of the tailpipe overnight. Anyone have any ideas if this is normal? Last winter is was...

    1972 Johnson 100hp pulling a tuber

    I've got a '72 Johnson 100hp electric shift engine on a '72 Glastron V176. Since I got it, it has always run fine. However, at the end of last year I was trying to pull someone on a tube and every time I gave it throttle with the tuber hooked up it would die. Someone suggested maybe it is the...

    '72 Johnson 100hp Cuts Out

    Last time I had my '72 Glastron Swinger with '72 100hp Johnson out, trying to pull a tube with a young teenager on it, the engine died every time I tried to accelerate. I cannot figure out why this might be. I do have a suspicion the clutch dog needs to be done, but I don't think that would kill...

    Original Cover and center windhsield - 1972 Glastron V-176 Swinger

    Hey everyone, I hope this is the right place for this question. I recently bought a '72 Glastron V-176 Swinger in excellent condition and I am looking for an original snap on cover for the back end of the boat. I have seen very few of these online when I look around and just wonder if anyone...

    1972 Johnson 100hp - Hydro-Electric Lower Unit Oil

    I just became the owner, well a week ago, of a 1972 Johnson 100hp engine that is in phenomenal shape. However, with the Hydro-Electric shift I have heard that there is potentially a different lower unit gear oil I will want to use with this engine. Can anyone give me some good suggestions for...

    NO WOT - 1975 70hp Evinrude

    I have a 1975 70hp Evinrude that was new to me just under two years ago. I have replaced head gasket, exhaust gasket, changed lower unit oil, cleaned/rebuilt carbs and done the impeller. Recently I had it out and it was running fine - 5400rpms and with four people in my boat, about 25mph. All...

    1975 70hp Evinrude - doesn't get up to speed well

    My 1975 Evinrude 70hp ran fine most of the summer - good idle, good pickup, etc... Then, found out I blew the exhaust gasket and was getting water in center cylinder. Replaced the gasket, took it out to run it and no water in any cylinders, engine would idle fine, but not pick up speed very...

    Choosing a new prop...

    jbuote - thanks. You're correct, it is pulses/revolution. I attached a piece from the manual. So, when I have tried to run it at the proper setting it is telling me I am only running 3200rpm at WOT.

    Choosing a new prop...

    I have a 1975 Evinrude 70hp with a 13-3/4x15 prop and at WOT I run 3200 rpm, according to my digital tach model: SRT-32R (set to 3p1r). This engine should be in the 5500 RPM range at WOT. I've been looking at a 13-1/4x17 prop, but would like to gain some other perspective. The engine is...

    Replacing steering

    I need to replace the steering on my 1988 Sierra 165v. I have a 70hp Evinrude powering it. However the steering was not made for my boat and was installed before I bought it, but the cable it several feet longer than it should be and is coiled up and the steering pulls to the right. What I am...

    1975 Evinrude 70hp

    I boat my first boat last fall. Mostly the boat has run well with a '75 70hp Evinrude. But, it starts somewhat hard. Once it is running it seems to run fine. I have check the carbs and they seem like they're not the issue. But I did some digging and found very minor scoring in the center...

    Water and scoring in center cylinder - '75 Evinrude 70hp

    In the fall of 2016 I purchased my first boat - a 1988 Sierra, 16' Fiberglass fishing boat - and it came with a 1975 70HP Evinrude engine. I took it out once in the fall before I worked on the interior all winter in my garage. It started hard, but ran after I used the manual choke. The only...
