    78 Johnson 115 starboard cylinder head getting hot

    Just blow some water through all those rubber hoses, try to reverse flush and put it all back together and test. 152° is not reached overheat yet but was probably going to. Has any of the paint yellowed on the head or around the block area? That might indicate that it had been overheated that...

    So far so good

    Rubber motor mounts....I disagree with a power loss but the motor not shaking so bad is better which usually happens at idle speeds. As you know those upper internal bolts that snap from abuse could definitely be catastrophic. I usually just go with it on 50 year old motors.

    Yes but did you put the sheet ice racing blade on it yet? Lol.... Thanks for the report. New style batteries have come along way.

    78 Johnson 115 starboard cylinder head getting hot

    A partially plugged thermostat could be problematic yes, open or not. Doesn't affect the tell tale so yes there is a high percent the problem is still lurking. Always frustrating.

    78 Johnson 115 starboard cylinder head getting hot

    Do you mean it stayed in the cup? You would easily see missing pieces. Well for now let's hope you've found your "smoking gun"!

    78 Johnson 115 starboard cylinder head getting hot

    How did the old impeller look when you replaced it? Any missing pieces? Small orifice's everywhere. Could be the stats but not likely. Racer is correct most likely on diverters and or examination. Slighten tighten first and then try loosing. I have torque spec fingers knowing when they will...

    78 Johnson 115 starboard cylinder head getting hot

    Salt water motor, yes or no? If not, mud dobbers area or other nesting bugs? Have you been praying to the outboards gods? Many things to soak it in before removing the head.

    Compression

    Anything oily works, tranny fluid has cleaners but not really necessary. Just free up the rings and coat the walls. The best is when you do it before you ever turn it if you don't know it's history. Head; flat piece of something, glass is used by some. I use 120 grit sandpaper looking straight...

    Compression

    Yes....it can but..... Running it more and testing it warm will help bring the numbers up but your numbers are acceptable to me. Learn how to resurface the head if you haven't already and send pics of this motor (whole and under the cowling) to see if you need other info to keep this wonderful...

    i have an 8hp evinrude thats locked up due to sitting 10+ years

    I've done them before, crosby exactly right...wood dowel and hammer. Did it to a 250 HP ones years ago and it's still running today. Rings get stuck. Best to pickle the crapola out of it....as for the other stuff, heat and your favorite penetrant. All fun but it won't be the best motor on the...

    So just to be clear, kill switch will not shut the engine off or it won't allow it to start?

    How to disconnect temperature sensor?

    A few drips of rubbing alcohol on the rubber and it will slide back like magic. Then unclip the mating metals.

    i have an 8hp evinrude thats locked up due to sitting 10+ years

    Did the motor rotate 360 degrees or more by turning the flywheel? If the gearcase is off the midsection then there isn't anything that should restricts it's movements. If you can't get the gear case off...that's a different scenario.

    Compression

    I use inexpensive tranny fluid or whatever else is laying around. Rarely do those come back. Compression testers are all over the board. I only trust the one I got in 1979.

    Kill Switch Lanyard

    Yes, my 2009 E-tec is the same. They made that feature so if you got flung, and the cord is strapped to you in the water, your mate could start the boat and come get you. Not sure I'm a fan but it was perplexing when I first discovered that. Now whether the op has that might be in question...

    Check/Fix/Replace Starter Motor 1996 50hp

    Without going back through the posts, and assuming this is a remote motor, have you removed the control box plug from the motor and then try testing the starting stuff back at the motor. Usually I jump the solenoid and at that point the kill circuit will somewhat be removed from the system. At...
