Wow. This is the hardest motor to find stuff for. I have a 30M 689 (S) 021815 motor. I took a stater, linkage, flywheel and stator off a 1985(I think) Japan 30HP 30EL 689/416715 Mariner and put it on mine so I could have electric start. I just need to know what the timing is or where to find a...
Does this look like water on the plug. Compression 136/139. After changed head gasket the first time I took it out seem to run good but lost 10mph. 2nd time I took it out it ran like pretty bad still lost 10mph. It used a ton of gas for the little bit I was out. It’s got good spark, clean carb...
my thermal switch is good but when I heat up the switch buzzer will not work. Could someone tell me if these work off a ground system? No volts to the “buss bar” terminal bar. Should the buzzer it self have 12 volts constant power?
Took the boat out last night, tried to use gas from last year the boat started running really bad change the tank right away made it about a quarter-mile still running crappy, change the plugs ran a little better but not 100%. Finish the night out got up this morning pulled the plugs bottom...
Does anyone know where or if u can buy just the brass bushing for the forward/reverse gears. Just picked up a used lower unit and someone bought new gears but messed up one of the bushing.
This lower unit is new to me so I wanted to change all the seals. Took bearing housing off tonight and the bearing stayed on the shaft. I had to tap the housing all the way off with a brass punch. When I picked the unit up, I noticed no end play on the prop shaft. All the gears look really...
First thing before I get started, any help at all would be greatly appreciated. I keep getting water in lower unit. So I tore the lower unit apart and have several question. (1)Does the cup on the water pump seal go up toward the motor or down toward the gear case? (2) The seal under the water...
Has anyone been able to find just the bushing for the lower unit gears on these motors. I have 2 50hp motors and looking at another lower unit this week and everyone I talk to say that when the bushing go out you have to buy the whole gear to replace them. Has anyone tried making their own...
Does anyone have (or tell me where to go to get) a manual for a 1989 force 50 that has step by step instructions on how to set up the shift linkage on this thing? Please
First off, thanks to all the ppl on here helping me out this project. Finally got boat set up and running pretty good. Now when I get to 22mph or more, it feels like I hit something in the water. I was in 8 feet of water cruising at 25 and scared the heck out of me, felt/sounded like I hit...
Which ones are better. I'm running BUHW and fouling out plug. Carb set good, air screw 1 1/8 new fuel pump diaphram, screen, straight gas. 50:1 ratio. Good compression. This boat runs perfect until the plugs start to act up. On open water it will run 29mph on a 16 foot fisher boat. Would...
Hello, question about 1989 Force 50hp new to me. Compression test was 135 and 140. Bought this boat from a guy that made it his project but he became ill and did not finish. It had some lower end problems. after removing the thermostat (thought it could be bad) and replacing water pump and...
