    1994 OMC 50 hp cooling system questions

    This question may sound ridiculous to some but I'm puzzled and a little embarrassed. I just put a '94 Johnson 50 hp back into service after a 2+ year down time due to illness. I noted no tell tale stream when running on the muffs. It doesn't overheat but there is not a tell tale stream. I've...

    Evinrude 70 hp midsection/bracket parts ?

    I have a 1977 Evinrude 70 hp I am restoring. I need to replace the bracket and midsection. I've been offered mid 1980's 85 hp parts and also some mid 1970's 50 hp parts. Does anyone know what models will interchange? I will use my powerhead and probably my lower unit. Steve

    94 Johnson 50 hp J50TLERE Carb Questions

    I've had some long term idle issues with this engine and undertook today to clean and "rebuild" the carbs. The engine has run great at high speed. These are very simple carbs and actually about the only thing in the kits that could be changed was the needle valve and seat, and the gaskets...

    84 Evinrude 70 hp power trim problem

    I just took on another project for one of my sons, an 84 Evinrude 70 hp. Trim and tilt worked when demonstrated on the former owner's boat. The engine was left in an "half tilt" position and transported on it's side in the truck where it stayed under cover until today (about 2 months). When I...

    Rectifier-regulator causing ignition failure... HOW COME?

    Johnson J50TLERE (94 50 hp). Intermittent total ignition failure. Today I finally got back to troubleshooting the engine now having a DVA Adapter and using the CDI troubleshooting information. The Stator Checks perfectly as does the trigger and charge coil. Since the stator checked correctly...

    1984 Evinrude 70 hp compression

    I just purchased a used 84 Evinrude 70 hp E70TLCRD not running with no spark. I'm sure I can get my money out of it if I don't fix the ignition problem by parting out the lower unit and power trim alone. BUT, I'm thinking about maby keeping it. Here's the question. The engine sat in a...

    94 Johnson 50hp. Battery drain through rectifier/regulator.

    I have a 900ma battery drain through the red charge wire to the rectifier on this engine. I haven't done any specific diode tests yet but have definitively determined the drain to be from the starter solenoid to the red wire of the rectifier/regulator. Any need to troubleshoot further or is it...

    Tilt tube removal questions

    I need to swap the engine mounting brackets and associated parts from a parts motor to another that we are going to refinish in order to minimize the area we need to sand blast and paint. The engine to be refinished has a good bit of bracket and lower unit corrosion from sitting in the water in...

    Power trim won't hold against reverse or trim back down under full throttle.

    Here's an odd (I think) problem I encountered today in the first time afloat in my new (to me) boat. 94 Johnson 50 hp. Had trim cylinder resealed prior to putting in the water for the first time. The unit will trim against engine thrust at full throttle but will not trim back down until the...

    I need a part number for a replacement water pump impeller housing for 77 Evinrude 70 hp. I've searched all over and find lots of numbers but nothing that comfirms fit. Anyone know the correct number that will come back as available rather than obsolete? Aftermarket is ok too. Steve

    94 Johnson 50 No Spark

    I'm trying out a virtually unused 94 Johnson 50 (owners Dad died the day after he bought it). No spark. What fuses may be in the ignition system? It is possible perhaps that the kill switch is malfunctioning... How can I temporarily disconnect it from the engine to test the ignition?

    Anyone Run their Yamaha 250 OX66 on Muffs?

    Does anyone run their OX66 engine on muffs? Everytime I try to run my 99 250 hp Salt Water Series OX66 on the muffs (even with a dual feed muffs) it overheats after a few minutes. NO overheating in the water however. ?? Steve

    77 OMC Trim and Tilt Questions

    I need some help guys. We bought a 1977 70 hp Evinrude with Power Trim and Tilt. This is the system with the rams outside the engine bracket. The port (trim ram I've been told) was frozen in place. The motor, pump, and starboard ram all work. I've acquired another system and in testing on...

    72 Evinrude 50hp overheating - HELP! I'm sinking here!

    I recently purchased a long stored fresh water only 1972 Evinrude 50 hp model 50273C. We changed the water pump as a result of the overheat alarm sounding after 5 minutes at idle on initial start up. It still sounded the alarm after the replacement of the pump. Today I pulled the water...

    Evinrude 70 hp bracket swap to upgrade power trim

    I wonder if one can upgrade the power trim unit to a later configuration by swapping out the brackets on a 77 Evinrude 70 hp with those from a later unit. If possible one might be able to use a more easily found fast track system or other later type. Please advise. Steve

    1977 Evinrude 70 Trail Lock Trim Tilt Problem

    Yesterday my son dragged home a "piece of junk" boat he acquired. It has an Evinrude 197 70 hp. I'm not familiar with how to set/release the trail lock arm on the engine and can't seem to get it to release. The power trim seems to not be lifting it high enough to disengage the arm. I suspect...
