Re: 1979 115 fried rings

dejavu,i to broke 4 long bolts and it sucked!heres what i did to remove powerhead.
fortunately i have a steel beam in my garage.drilled a hole in beam to attach a heavy duty chain.back up trailer hook up chain to lifting eye on motor then cranked up on trailer jack thereby lowering rear of trailer .that put the upward pressure on the motor.then i used a 4 foot prybar to pry up on the 2 furthest back studs.because of the broke studs i had to stand on the exhaust housing protrusion,very back just above the lower unit which was removed,and shook the hellll out of it back and fourth.while stillprying up occasionally.all in all it took about 3hrs.by myself.

or you can cut the bolts with a dril threu the adaptor plate.
mark where the bolts are and drill until you cut the bolt.
after you reinstal the new rebuild ph and torqeud the ph bolts down fil the holes with bondo or jb weld.

its the easyest way i know.

Re: 1979 115 fried rings

okay, im still trying to get the power head off. I still have one bolt on each side in the front and the back. I think im going to try to cut them with a sawzall and lift it straight off. Im not sure where to drill out.

As for the cylinder, I still have decided. I only want to put in a tops of $500 for it to be fixed, so im thinking either one over size and just clean up the other 3 and put new rings on them, or 2 over size on the starboard and then cleaning up the portside and replacing the rings. I will probably just do one though, just to get the compression back up so i can use it to ski again.

How much is a .030 bore usually cost for one cylinder?

Re: 1979 115 fried rings

a piston is about 90 dollars up to 120 dollars.

i would be very very very careful with the sawzal.
i would drill the bolts threu the adapter plate.
with the sawzal you probebly wil cause unrepairable damage to powerhead or adapteplate.
they have to seal water tight.
draw a line from the top of the bolts to the bottum and cut them treu the adapterplate.

the bolts are never seized in the threats its always oxydation and crud buildup at the shank of the bolts.

where are you planing cuting the bolts with the sawzal?

go ahead and see what you got.

Sony: the depth of the bore usually doesn't impact the cost, I paid $60 CAD per hole on my engine... which I thought was really reasonable. I got quotes between $60 and $85.

Re: 1979 115 fried rings

I see.

I was going to cut the heads off the bolts and try to pull the powerhead straight up, but now im more concerned about other things. While talking to my father, hes told me that i'll probably have to get new electronics, and that its really not worth dealing with the bearings on the camshaft. I don't want to make this a huge project, because right now it seems more than enough for me to take on at once.

He also told me theres a guy in pennsivanna that specializes in rebuilding motors. You ship him yours, he tells you what he can use on it and then he either fixes it or gives your a replacement for it. I am starting to look into that, because I think that might be more practical now. Does anyone know the website for that guy or anything?

Re: 1979 115 fried rings

Anyone know of that guy or bussiness?

I'm thinking that'd be more practical, because I've been reading alot about all the gaskets and other little things i'd have to do as well, and I think it'd cost alot more than I was thinking.

Re: 1979 115 fried rings

I've broken 4, and gotten 2 out

Dude, get a can of PB Blaster and give all those bolts a good bath, let it penetrate at least an hour with applications every 15 mins. I use it on every bolt I remove, that's $4.00 well spent. Good stuff, don't even think on using Wd40 that is history.

Re: 1979 115 fried rings

haha, i did use PB Blaster haha. Still broke them.

Re: 1979 115 fried rings

When your dad said he thinks it may need electronics.
That would add up $$$ very quickly.
As long as they worked and are not damaged I would reuse them.

Re: 1979 115 fried rings

I decided to scrap this engine, because i found a 1970's evinrude 115 that just needed the electronics. (which I have)


I just hope all the electronics will swap over.. as im not sure of the year. I don't have the motor in my possesion yet, but i bought it complete for 100$ with a good powerhead, so I should be able to get a strong working engine out of the two I now have.

The evinrude is a gold one, its a 115 with a white top with a red and blue strip. If anyone could tell me the year and if my johnson electronics would work that'd be awesome. Thanks

Re: 1979 115 fried rings

I think its $$ well spent.
as long as the powerheads are the same you will have a running motor pretty cheap.

You should check compression to make sure you got a Gem and not a anchor.

If It was mine B4 running I would ensure the carbs are clean(rebuild), new wp impeller, and once its running decarb.

100$ is a pretty good deal if it runs good.

For a few hundred you will have a good usable motor that you can use for a number of years.

If your ambitious you could part out what you have left on e-bay or be like me and be a pack-rat with the extra parts for spares.

Re: 1979 115 fried rings

the motor im gunna pick up was running 2 years ago, but the electronics were stolen off of it. Its been sitting less time than the one i have and it ran well before it was vandilized. I am a little worried about first starting it up, Im gunna put some oil in the spark plug holes, and give it a shot. I will replace the wp too as long as it starts and runs. The carbs I will also clean or rebuild if they need it.

Re: 1979 115 fried rings

Awsome post Dhadley about coking on the v4's. I have a 1975 85hp and noticed the black stuff when i started it up this year, coming just from starboard side around the spark plug holes and thought it may be other problems, ignition or carb problems.
What do you use to de-carb the engine? Regular carb cleaner down the carbs when it is running or something else?

Re: 1979 115 fried rings

i'd like to know as well. I don't want this happening again
