    Rectifier Upgrade

    Sorry for the lag time. I will check battery voltage today, while running in tank. I will also check tach settings. The tach, sometimes, is sitting on 10k before I start the motor, with the key on. It only does this after motor runs for a while. On initial startup after sitting for a while...

    Rectifier Upgrade

    is there any benefit from the added regulator? The original is only a rectifier.

    Rectifier Upgrade

    I have a 1978 Johnson 115hp V4 crossflow that this fine group has helped me with several times. I have been having issues with my Tachometer showing 10k rpm's more than the engine is going (ex. tach reads 72k at WOT). Also, my voltmeter gauge is pegged at around 16V once the motor is warmed up...

    TACHOMETER ACCURACY

    I want to bypass the wiring, if possible. Hopefully to eliminate the wiring as the cause

    TACHOMETER ACCURACY

    I have a tank. What type of prop?

    TACHOMETER ACCURACY

    The tachometer is 4-5 years old. The brand is Faria. I did buy a handheld tach, but it's useless out on the water. You have to put a piece of reflective tape on the flywheel and aim the tach at the tape from less than 12 inches away. It's useless while driving the boat. I have a timing light...

    TACHOMETER ACCURACY

    I have a 1978 Johnson 115hp V4 crossflow. I'm having issues with my Tachometer. It seems to be accurate up to around 2000 rpm. But, when I push the throttle down tach climbs to around 7200rpms, and I'm not even at WOT yet! I think WOT should be around 5200 on my motor. Obviously, my tachometer...

    78 JOHNSON 115 TACHOMETER PROBLEMS

    I'm not sure if this is the right forum to post this so let me know if it is not. I have a, relatively new, tachometer gauge mounted in the dashboard of my 82 Ranger that is doing some very strange things: when I turn the key on at the motor's remote control the needle on the tach will climb...

    78 Johnson 115 intake manifold

    To Racerone's comment. I've changed just about every part on this motor: Complete ignition system (timer base, stator, power packs, coils, etc., starting, system charging system, fuel pump, cooling system, resealed lower unit. I have put way too much money into this "50 year old motor". But, I...

    Thanks. Any recommendations on Gasket compound?

    78 Johnson 115 intake manifold

    Hello, I am rebuilding the carbs on my 115hp. After pulling both carbs and peeling off the gaskets, I noticed a "chip" in the intake manifold where the lower carb mates to it. See pic. Is this something that I should be concerned with? TIA, Bryan

    78 Johnson 115 starboard cylinder head getting hot

    I just wanted to thank everyone for their input and advice. I didn't end up pulling the heads. I backflushed through the thermostat hoses with the lower unit off. I should have done it over a bucket so I could see what came out. I also replaced the T- stats, relief valves, and springs. Also...

    78 Johnson 115 starboard cylinder head getting hot

    better to run on muffs or a barrel?

    78 Johnson 115 starboard cylinder head getting hot

    That may not have made sense. I meant : where did the chunk of salt exit the motor when you backflushed through the hose?

    78 Johnson 115 starboard cylinder head getting hot

    The new remote that I installed a few years ago came with a new horn. The horn works and so do the heat switches. I know 152 isn't overheating, but it's kinda hot for 90 seconds running. Although, the warmup lever was up all the way. What got my attention was the tell tale sputtering. Never had...
