rusted 115 johnson 1976

[gty2k2000]

i have a 1976 johnson 115 johnson V4 it is in perfect running condition.but its rusted to hell along time ago it had to be rebuilt and when the marina put on the water jacket plate they craked it. so they jb welded it. then it eventualy split openspraying saltwater every were i eventualy replaced it and stoped the leack but now all the bolt on the head are rusted to hell. should i try to replace them befor its to late or should i let them be in fear of snaping them.<br /><br />i dont want to abandon this motor it starts better than any new outboards iv ever seen.and it has a lot of sentimentle value

HI<br /> can't really tell, but, the words "rusted to hell" sort of says it's time to send it to the wreckers!

Re: rusted 115 johnson 1976

since you've worked on this area of the motor .... can you put a wrench on it and "feel" if it is going to come out ? If so,replace the ones you can safely remove,and leave the "bad" ones.IF you ever have to remove the plate again,deal with the rest then.<br /><br />DHP

that sounds like good advice to me, if it is only the bolts trhat are "rusted to hell" then a try with the correct size tool to see if they release is a good idea, you can "feel" the bolt move as different to 'twist" (snap off)

An oxy-acetylene torch, or even one of those hardware store oxy-MAPP torches, makes working on saltwater V4s a lot easier. The motor parts are aluminum, while the bolts are steel. These metals have different rates of expansion with temperature change, so when you hit them with the torch they differentially expand & break lose their 'crud' bonds.
