- Video on restoration of a 1977 1500 with compression 150psi plus!!!! Can I make it talk!?!?!?!
As always, thank you for your support with bringing these engines back to life!!!!
The cap is known to crack, Mercury does not make them no more, so I bought a lathe (a cheap one) and made mine out of Al. works like a charm, drill a hole in the side and taped a 1/8 NPT and used a Al. nipple. Took measurements for the plastic one.
Poor retiree here. Got a 1978 900 on a trade. Compression is 1 = 90 2 = 138 3 = 135 4 = 146 5 = 135 and 6 = 138. Did a decarborizing and got 1 = 91 2 = 135 3 = 130 4 = 140 5 = 130 6= 130 I have no way to rebuild this motor. Tools I have, but no way to remove the motor from the boat or to work on the motor. I travel full time and only have my travel trailer my truck and whatever RV site I am on. What is the worst that can happen if I run this motor. Some other wonders, someone put 150 hp WMK 22 carbs on it. I found NOS WMK 23s to replace those. Have the new CDI wiring as the old was bare in many places. Wonder it did not burn up. TDC is TDC. Get spark OK. Tester shows good spark jumping the gap in sunlight set at 20. Found a NOS switch box if I needed to buy that, but with good spark I see no need.
Hello MerCSon. My dad and I have a 1959 Lonestar Cruise Liner with a 1965 100 hp Mercury. I’m not familiar with CZcams and I created an account to be able to send you a message. We are wondering if/how to contact you with a question. We have watched tons of your videos and hope you might be able to help us. Thank you!
I have an 1984 90 T O P. Sat in storage for 33 years. Has less than 200 hrs on it. Awesome hole shot
I had similar issue with my 1150. rebuilt carbs and it was still not working. Tried starting while gently squeezing primer bulb and it fired up. Ended up finding a hole in the diaphragm of the fuel pump. Now just waiting for my second CDI Trigger assembly. I put a new one on and it lasted less than a dozen hours (over the last year) because the rotor disc was rubbing against the housing which warped the disk and rubbed off the epoxy that holds the magnet in. I ordered a set of shims to ensure proper spacing this time! I had 2 plugs with little to no spark due to disk contacting the trigger at that point of the rotation because the disk warped. Now no spark because the magnet keeps pulling itself out of the trigger and contacting the disk continuously. Ridiculous that they don't sell just the piece that holds the magnet since it comes off with those 2 little screws, and that housing isn't cheap! That's my diagnosis anyway. Ever see issues with CDI trigger housing because no shims/improper spacing/ disk contact with housing?
Bummer.. you could hear it will run and wants to run .. fuel issue for sure.
that's one hell of a battery
This is the same 1976 150hp motor I’m working on. If you want to sell me one of you extra a power packs?
Question: I have 1979 mariner 115hp starts right up & idle just fine, getting out of the No wake zone I throttle get on plane it’s going 16-19mph give it more throttle to 30-35mph for about 2-4min I give it more throttle it bogs down and dies, Like not venting the gas tank, every time I try get speed above 39 it shuts down, at times it doesn’t want to restart even with the fast idle lever up. Then when it does start everything seems fine I can lift the the fast idle level up and responds good. No mater if I gun it or slowly work throttle it shuts down at 38-39mph any idea what the problem could be? Thanks for your help.
Wow low hours
I had the 9.9 with that decal blue as a kid and would like a 150HP
Just got mine running on all six last time out and it broke a ring or burnt a piston. It was sounding so good on the last run to. It had been sitting 21 years. Totally sucks.
Hi, I have an inline 6 merc 115 it starts by barely turning the key, it’s idles flawlessly. In gear, in the water, when I hit the throttle it jumps out of the hole and then falls flat on its face, but doesn’t die out. Do you have any idea what the problem might be ?
Hi love
Hi mercson this is CJ again thanks for replying and for the video I seen it and I have same problem on this video I have spark and carburetor clean but want start what I have to do? Thanks
Does anyone know if the springs that work the needles in carbs available, separately or can be improvised.
Hey there! I've been collecting the 6cyl mercs for a few years now. Currently I've got a 150, 2-100 and a 1963 800. Was hoping to talk with you one on one, as I want to get all of them running. My 71 100 is running. Parts are my biggest issue.
I have this same motor on my 1977 glastron cvx16,is it normal for the read valves to go bad on these motors?all I see is the hardly ever go bad,almost never do they fail.I had same issue with the pump cap.i tried different things pic cap,obviously weld.i finally found a metal one off a guy on one of the mercury forums for 25 bucks
MercSon, when I crank the motor, it will run until I let loose of the key and when it a springs back to the on position it dies like instantly? Model 1150 115 hp 1966-1968 thunderbolt ignition, no points, please help!
I have a question about my inline 6 outboard, when I have it idling the prop still spins. Is that normal for this engine?
