    78 Johnson 115 Overcharging??

    Took the (bass) boat out yesterday and motor was running good. The voltmeter was reading between 13-14.9V for most of the day. I never opened her up to WOT and cruised at about 4500-5000 rpm. Then on my way in the voltmeter was reading a steady 16.7V and even went all the way to 17V for about 30...

    78 Johnson 115hp Crossflow Stalls When Put into Gear!?!

    V4 CROSSFLOW: SPRING MAGNET IN LOWER UNIT??

    Hello. I am replacing the seals in the lower unit of my 1978 Johnson 115hp. My question is about the football shaped magnet spring.

    Johnson V4 Crossflow Throttle return

    Hello. On my 1978 Johnson the throttle doesn't seem to be returning properly. At first, I thought it was the timer base. Is the throttle supposed to return to the idle stop screw and the timer base back to its starting point? No difference if the cable is off or on hopefully I'm explaining this...

    What kind of lube for timer base??

    Hello, I am replacing ignition components on my 1978 Johnson 115 V4 Crossflow. My old timer always seem to have problems returning back to idle. Some suggested that may have been because the grease dried up. The old one was brass, but the new one is all plastic. What type of lubricant should I use??

    78 Johnson 115 Carb Kit??

    Hello, I'm looking for a carb kit for my 115ETL78C. The info on my usual parts websites is conflicting. crowleymarine doesn't recognize 115ETL78C, but gives me 115ETZ78C, for which the carb kit is p/n 0439076. They are a bit pricey so I went to wholesalemarine to look for a Sierra kit. They give...

    I have a spare motor that I want to test run. Do I need to hook up a remote control box to get it to run? I've only ever tested tiller motors off the boat. Is there a way to run a 115 without a remote control? Thanks.
