    Another dumb question, what is the difference between Johnson and Evinrude motors?

    What is the difference between Johnson and Evinrude motors? I have one of each and can't see any difference. The parts are interchangeable as far as I can tell.

    What are my best options for covering bunks?

    I just replaced the bunks on my trailer with PT wood and need to cover them. I'm wondering about what my best options are. I have some indoor/outdoor carpet left over from redoing the interior of the boat and even some heavier carpet left over from my house. Are either of these a reasonable...

    Why does an Evinrude airbox cover have two holes plugged

    I have a1975 Evinrude 135 and have always wondered why two of the fours breather holes have plugs in them. I'm thinking I should take them out to allow the engine to breath better. Anyone know why they are there and should I leave them in or remove them?

    Piranha prop review

    I needed a new prop for my boat (16' low profile speedboat) with a Evinrude 135. I had a couple of 17" pitch 3 blade props but wasn't ever happy with the performance. I decided to try the Piranha prop since they will exchange blades if you don't get the right pitch for your setup. I ordered a 4...

    1975 Evinrude 135 not putting out full power.

    I have an 1975 Evinrude 135 that does not seem to be putting out full power at WOT. I've had a similar boat (16' low profile speedboat) with a Merc 115 so I have an idea what it should be doing. The engine just doesn't feel like it is running all out. I pulled the cover off and inspected the...

    Will a 1975 135hp powerhead fit on a 1983 115hp unit???

    I have a 1975 135hp engine that runs real strong with good compression. Problem is, it does not have tilt and trim. I have a 1983 115hp with tilt and trim but it needs a rebuild. I was just wondering if I could replace the 115 powerhead with the 135 so I'd have a strong 135 with new style tilt...

    Trailer weight limit with 1" spindles.

    I have a small boat (16' low profile with Evinrude 135) on a trailer. The trailer has 1" spindles. If I'm correct, this means it is a 2K lb axle. The tires are brand new and rated for 2600 lbs (1300 lbs each) and it has 4 brand new and well packed bearings. My thinking is that when we go...

    Anyone know the tach setting for a 1975 Evinrude 135?

    I wired up a tach to my boat and the rpms are off. I know this is based upon the pulses it gets from the flywheel but can't seem to visually identify how many magnets are in it. Does anyone know how I can determine the proper setting (or know what the proper setting is?). I can probably get...

    Recommendations for Martinez Lake and southern Colorado River.

    I've been boating/waterskiing the Colorado River since the mid 80's when I lived in LA. We would generally go to Havasu, Parker and Big River. Now that I live in San Diego, looking forward to exploring the southern end of the river. Gathered up the family a couple of weekends ago to see what...

    Anybody use low pressure fuel pumps with their outboards?

    I recently bought a low pressure fuel pump (3-5 psi) to replace the bulb for my outboard. The reason I thought I needed it is because I installed a tank in the bow and there is 20' of hose back to the engine. My plan was to use a on-off-momentary switch to run it. I'd use the momentary side to...

    Evaluating a 1983 Johnson 115 for rebuild

    I recently bought a 1983 Johnson 115 w/ tilt and trim and control box to replace my 1975 Evinrude 135 w/ manual tilt and trim. The newer engine has lower compression compared to my 135 (130 psi for the 135 vs. 85 psi for the 115). Even though it needs work, I couldn't resist buying it cause the...

    Carb rebuild vs. spraying in carb cleaner

    I have a 1975 Evinrude 135 that runs great at WOT, doesn't idle so well though. It has reasonable compression (125-130) on all cylinders so that doesn't appear to be the problem. I'm contemplating a carb rebuild but with only a month or two left of boating season here don't want to do to much to...

    1975 Evinrude 135 stator/charging issue.

    I'm finally finishing up my project boat and took it out for a test run. The motor doesn't seem to be charging. I look at the wiring diagrams, older forum threads and understand the fundamentals of the system, but when I started taking readings from the components, I get real strange data...

    Tilt and trim for a mid 70s Evinrude 135hp

    Re: Tilt and trim for a mid 70s Evinrude 135hp I should have included this picture of one of my brackets in the earlier post.

    Tilt and trim for a mid 70s Evinrude 135hp

    Re: Tilt and trim for a mid 70s Evinrude 135hp I have the option to buy this tilt and trim and am wondering if anyone knows how difficult it would be to modify to work with a 73 135 hp Evinrude.
