I'm not familiar with a degree wheel. Can you point me to a resource on how to find TDC with a piston stop and degree wheel? I'm a shade tree mechanic and did not take engine 101.
Sounds good, I was going to use a whistle as I have never used a piston stop. Are they more reliable? That isn't rusted through just the image. I inherited this boat am just trying to get it running smooth. Thanks!
Not sure how to go about setting the timing as the tab is completely deteriorated. Any suggestions? 1989 four winns horizon. GM 4.3 with omc cobra outdrive.
EDIT- Can I find TDC and then mark the block/balancer then use a timing light with advance?
I was replacing the gimbal bearing on my OMC cobra outdrive when I discovered an extra part. I had successfully removed and installed the new bearing, and when I went to take the old bearing off the removal tool, I noticed there was a spring like retainer clip that I can describe as what looks...
Is there supposed to be a grommet in pic 7 w/ the exhaust bellows? The copper tube running through the stern?
Ill have to take a closer look, I am not certain. Ill get back after, after work tonight.
I got this Barr Kit. I did disconnect the raw water intake off the thermostat housing after the overheat, after waiting 1 hr., as we had another boat with us and they took the kids for spins around the pond and used my boat as the swim platform anchored just off the shore. It definitely did not...
I have been trying to get a 1988 4.3 OMC Four Winns with Cobra Outdrive going. I replaced the bat wing manifolds with 2 piece set up as described by Lou C in previous posts. I performed the upgrade but then overheated almost immediately once on the water, melting the paint on the new elbows. I...
Ok, I’m moving along. Since the manifold was off I decided to pop the valve cover and take a look.
Looking pretty good no signs of water getting in, feeling confident.
Getting the studs out was a PIA. Generous amounts of pb blaster and heat did the job.
Since the covers were off I decided...
Good idea, I need to find the torque specs. I can’t seem to find a manual.
EDIT: Scratch that some more searching I found one online. 86-98 OMC Sterndrive Manual
EDIT 2: 30 ft.lb for the intake manifold on this engine, 18-22 for the exhaust for anyone that happens to come across this in a search.
I had a mechanic over to take a look at it, there are no signs of a cracked block that we can find. It ran for a bit before noticing cracks in the tops of the manifolds and water spitting out. I'm not sure if this is a result of freezing, it seems like an odd spot to crack from freezing, up high...
EDIT: Sorry Wrong Location, please delete. I will post in the appropriate forum!
I was given a 1988 Four Winns 4.3L OMC 2V which had been sitting for a couple seasons. The owner said they winterized it thoroughly but when I got it started up water was leaking out of cracks on the manifolds both...
It’s odd because the manual doesn’t say anything about 6 inches to the lower shift barrel but every video I’ve watched says to measure that distance. Also they say put it in forward to attach the throttle control cable, does this mean full forward or until that first notch you feel going into...
