    Just want to be sure before I order parts

    I have a '76 70 HP Johnson 70EL76D that is new to me. The guy who sold it to me started it, shifted it through gears, we did a cylinder drop test, etc, so it all checked out. One thing the boat it was on did not have a tach. When I got it installed on mine, I found the tach did not work. I...

    Cleaning Tilt Tube

    I have a 76 70 HP Johnson that I am getting ready to hang on my boat. When I bought the motor, it came with the full steering cable from the boat it was on due to the fact that the end of the steering cable was frozen inside the tilt tube. I managed to free the cable, and in fact have...

    Steering Confusion on new-to-me 1976 70 HP Johnson

    I have acquired another motor in my eternal quest to own a working motorboat. This time, I am running a 1976 70 HP Johnson. I bought it from a gent who had not run it (he got it as part of a rig he acquired for its trailer), but had the motor inspected by a mechanic who verified it was in good...

    Anyone ever pull the powerhead off of a '72 Evinrude 50

    Hi Trying to pull the power head off my motor. I have the OEM manual, and have removed all the nuts, bolts, and bits they instruct you to. The next instruction is "Lift the motor and lower cover off and set on your workbench". The dang thing is not budging. I really don't want to force it...

    Spare/second prop choice?

    So, I have found what I believe is the correct prop and setup for my rig and the way I want to run it. I have a 1976 yarcraft Yankee 15' tri-hull bowrider with a 50 HP motor. I get it running at 6K RPM WOT loaded with about 700 Lbs (boat capacity is 825) at 26 MPH (by GPS) using a 13p 3-blade...

    Prop exchange options?

    So, I have my 1972 50 HP Evinrude running as it is supposed to (Max 6000 RPM, WOT 5500-6000 RPM) with a 13p prop. Whatever previous application the motor had, it was running a 17p prop (which I believe was the standard prop for this motor when new). I really wanted to have a spare prop 'just...

    Amazing what you find in the dumpsters

    So, the family and I are on our way to Costco last night to pick up some supplies for my 40th birthday party. We went in the back way instead of the front to avoid some traffic. We are cruising by the back of the store, the dumpsters, and I spy what looks like a small boat pontoon (think a...

    question about lights

    I knew my trailer wiring was somewhat screwed up, but it was a low-priority item as opposed to the re-build work on my boat. Now that the boat is done, it was time to address the wiring. Apparently the previous owner had some problem with the original lights and wiring, and their solution was...

    What are the symptoms of dropping a cylinder?

    I have a 1972 Evinrude 50 HP model 50273C which is starting easily (once warmed up) and running well at its mid-range. It runs very smoothly at WOT, although its not spinning at the correct RPMs (its running about 4400/4500 RPMs). I am having problems getting it to idle at under 1200 RPMs, and...

    First lake test a qualified success. Need some advice.

    I put my 15' Yarcraft Yankee powered with my '72 50 HP Evinrude (90273C) on the lake on Sunday, and had a qualified success. I did have a couple of issues i was hoping for some help on: 1. When you do the carburetor adjustments, the motor should be in neutral, right? The motor would not idle...

    Prop help for older boat 15' trihull w/50 HP Evinrude

The Prop - Assume it was the original that came with the motor. Its a 13 1/4" 17 Pitch aluminum prop (that's...

    Learned something new about hydoelectric shift

    My boat is just about ready for water tests/adjustments. Yesterday I muff-tested the motor (1972 Evinrude 50 HP), since it has not been run in about a year. After a few mishaps with the throttle control (I hadn't secured the throttle cable in the right place, so it wasn't throttling up) I got...

    keep inspection holes

    So, I had this nagging feeling that I had wet foam underneath the deck of my 76 Yarcraft Yankee. It just felt a lot heavier than a 15' tri-hull should have. The good news is that inter-hull space was high and dry (also, there was no foam in there, so someone must've rebuilt that deck at some...

    Hello all I am getting to the end of my re-hab project on y '76 Yarcraft Yankee. I've re-installed the outboard (the one referenced in the subject) and controls. I'm trying to re-connect all the cables from the control to the motor. The big round plug is obvious. Apart from the round plug...

    Correct wiring for this Tachometer

    This may seem rather obvious, but I only want to wire this tach up once. I have purchased a tach, image is below. Its to connect to my 1972 Evinrude 50 HP. The wiring diagram in the manual shows the gray wire coming out of the control is the tach wire. I have located this wire. The tach has...

    Cleaning a plastic gas tank

    I have a spare Attwood 6 gallon plastic fuel container with all the connections for my motor that was originally on the project boat I am hopefully going to launch in the coming week. The tank had un-stabilized fuel in it that soured. I've emptied the old fuel out of the tank, and wanted to...

    Which paint

    I have decided to paint the deck on my '76 Yarcraft Yankee. I've read on several different threads that porch paint with some kind of traction additive will work about as well as topside paint. Specifically, Glidden Porch paint. I went today to my local HD, and there are two types there. I...

    Bringing on the bad luck

    I'm a week or so away from putting my '76 Yar Craft Yankee on the water after various hull repairs and repower. Its pictured below in my signature. Yesterday, my daughter asked me what we were going to name the boat. Now, seeing as it didn't have a previous name, I am free and clear from the...

    Does gelcoat require pigment?

    Hello all I am fixing some dings in my old '76 tri-hull. I've filled the worst offenders with 3M Marine Filler putty, and was told that it still needed gelcoat over top of the filler for UV protection. There is no way I am going to be able to match the faded, yellow color of the boat, so I...
