Bought a good used boat and the Johnson 115 came with it. The boat and trailer were worth the money alone. The motor was original on boat and I am third owner. Anyhow I replaced the starter and rewired the solonoid so I could start it as the seller used a rope. Motor started after a few seconds but idled very high and would not back down. The tach is not hooked up or does not work. My voltage meter says charging is up and down and not a constant 14+ volts. The worst surprise is forward gear and neutral seem to work okay but no reverse. Owner said he had serviced lower unit, new water pump and spark plugs but I am not sure what to believe. My question is should I continue to work on and put more money into this motor or look for a replacement? Is the older Johnson worth the time and investment? Any and all opinions are most welcomed. Confused in Knoxville, TN. Thank you.
