So i am going to be getting rid of my 1986 Merc Tower of Power 115 jet this winter and repowering with a Yamaha 150 and converting it to a jet foot from outboardjets.com.
I am currently looking at a late 80's - mid 90's V6 150's Yamaha's and I'm wondering what i should be looking out for as...
I have a 86 inline 6 115, when i pull the fuel line from the carb side and crank it over it pulses once then nothing.
I have rebuilt it using a kit, all but the check valves.
New fuel line through and through and have tried a different tank.
Should this pulse fuel as cranking non stop.. and...
This is a fully rebuilt 1986 merc 115 L6. 40 gallons ran through,break in has been done.
Im thinking i have a fuel delivery issue and i went to test my fuel pump (old style/rebuilt) by pulling the line off the top of the pump that feeds the carbs. I hit the kill switch and turned the key.. it...
During disassembly of my 1984 Merc 115 L6 the upper bearing slid off, it barely spins freely and i will be replacing it.
Would a bad upper bearing cause poor acceleration and low rpms?
The rest of the electronics and carb's that were on it are the same thats on my rebuilt 86 and that is...
What is the correct size socket to remove the connecting rod screw/bolt on a 1986 mercury 115 hp. It is just the screw, not the bolt and nut.

As always.. thanx in advance..
I am in the process of rebuilding my 86 Merc 115 L6. I had Cylinders #3 n #4 and #5 run lean and chew up the rings. I can not feel or notice and marring on the cylinder walls (i got lucky), i caught it before it got bad and stopped running it so i didnt do more damage. The Middle and lower carb...
So i have did the link and sync procedure based on the directions i found here on iboats. Between that and my manual i have it idleing great and hittin hard at wot.
I know i don't and didn't go past 21* while setting it and i have read about detonation and want to avoid that, im slightly under...
1986 mercury inline 6, converted to ob jet.
Motor starts and runs great, idles at 800.. all day and wot is 5300 - 5400 rpm..
The issue i am having is when i am at wot and go into a power slide it drops down to 4500 rpms. it isnt cavitation of the impeller or it would raise the rpms..
I went...
So i have 2 CDI switch boxes (NIB), would it make sense to swap them out with my current stock ones prior to failure?
I normally believe the theory if it ain't broke don't fix it.
But it seems with these switch boxes once they go they tend to take cylinders and other components with them...
motor is a 1990 30 hp J30TELESS
Started it in water and noticed the cowling was filling up with water, upon further inspection during running noticed water coming out by the top spark plug. It isn't coming out directly next to the spark plug but next to it on the case through a gasket.
I am...
There are 2 bolts on the front of my 115 Merc 6 cylinder..
One between carb 1 and 2 and one between carb 2 and 3. I noticed one was loose and the flange/keeper was locked down.. I tightend it back up. The shop who did the rebuild must not have put the flanged keeper down..
Should i have any...
Yesterday i noticed my system wasnt charging but my tach was working. I got home and tested the rectifier and it was bad, swapped it out with a new one. At WOT it charges at 16.5 Volts and the tach works fine.. at idle the tach gets erratic and it sits at 700 which is where i have it set to...
I have a 1984 merc 115 6 cyl.
While rebuilding my fuel pump a cple weeks ago i notced in my manual doesnt show a spring and a retainer that the online parts diagram does..
Diagram
It's part number 22 and 23..
Did they leave that spring and retainer out of the image on the manual...
1984 mercury 115 inline 6 (6524769)
I am having an issue with RPM's dropping at WOT. At WOT it jumps up to 5100 RPM and slowly drops down to 4900 then surges back up to 5100 and so on. When it surges it sounds like it is running strong then tapers down to 4900, also all 6 plug's have drops of...
I have been lurking on this site for awhile now. With all of the information i have been able to rebuild my carbs/fuel pump/starter/compression and spark test and a Link and Sync and set the timing on my 84 Merc 115(which runs great now).
Thanx to all of the knowledgable people who take time...
