Thanks for the replies. I read the cdi guide. For no spark on any cylinder; The second thing to check after disconnecting the black/yellow stop wire is to disconnect the 2 yellow wires going to the voltage regulator from stator. I will try in the morning. I hope that's it. I will update for...
I have a 1995 mercury sportjet 90hp which is an 85 hp 3 cylinder force with mercury ignition. It runs great and will run as long as you want. But when you try to restart there is no spark. Let it sit for an hour or so and again will run the take out of gas if you want but shut off and again no...
I came across a 40hp big twin with a winged gearcase. I Iooked it up and the parts breakdown shows it being called an
"A" suffix gear case. Any info on this design would be great. Also does it use standard gears? Thanks for any help.
Looking over some electric choke solenoids and wondering what the differences are. I see single wire with ground and dual wire with ground. I looked at the wiring schematics for several years and is seems the dual wire with ground type are wired different ways. Some run the second "hot" wire in...
I'm working on a 1976 85 hp Evinrude. Both water tube guides are missing part numbers 0314765 — GUIDE,WATER TUBE LONG and 0314081 — GUIDE,WATER TUBE SHORT. Part number 78 and 91 top left of the picture. They are on top of the water pump housing. It has been a couple years since I had one of...
I'm rebuilding a customers 2000 johnson J50PLSSM. The lower piston and cylinder look like they didnt get any oil. Upon inspection when pulling the pistons out I noticed that the pistons were oriented correctly on the rods but I believe that one of the rods were installed at some point with one...
I have a leak that I cant figure out after I reinstalled the power head on a 1987 50 hp. I don't want to pull it again if someone has some advise. It's leaking just behind the bottom left corner of the exhaust box. I pulled the exhaust box back off and used 847 on all gaskets but no joy. I'm...
I'm working on a 1989 force 125 hp. I have static timing at 28 degrees wot. The issue (maby) is when I back off the throttle a fraction the trigger actually moves further advanced then wot. It's like it goes to full advance then comes back a degree or 2 at wot. I have not tested the static...
I'm working on a 1988 50 hp force with prestolite ignition. All checks out well ohms but the trigger on 1 pair starts at .43v and drops to less then .3v while cranking. This is the side without spark. Very strange that it shows 50 ohms like the other side though? The side that fires shows 1.5v...
I have used all of the normal methods of converting a dual line engine to a fuel pump with great success. My questions is that I have some leaf plates for various engines that don't have the check valve holes machined into the plate. (5.5 hp and 18 hp) Can I just use the newer leaf plate and...
I was working on some old outboards and noticed that the 10 hp 1956 Johnson gearcase, gears, water pump, etc are the same or very similar to the 22ci 18,20,25 models from about 1957 up starting with the 18 hp fastwin. I generally don't buy anything older than mid 60's but got a great deal on a...
I was at the launch today talking to a guy who has a bayliner cobra with a 125hp force. He said he liked everything but how hard it pulls when running. I told him about the minor grinding that I have done on all of my snouts to move further to the left to completely eliminate any steering pull...
