Good day, 1981 Johnson 9.9hp. I very small thin fuel line goes from the carburator to the fuel pump. It splitted open and needs to be replaced. Local marine dealer do not have such small fuel line. Any suggestions on where I can find a replacement hose of that size ? Thank you
Hi, 196? late or 197? early 6 HP Jonhson. (Olive green) Would "pro's on this board know the prefered prop for this engine since it will be pushing a 12 footer alu Lund deluxe with no more than 2 adults onboard ? thank you all.
My Force OB can idle in water barrel flawlessly for hours. Once on river still idles ok at the dock. Once I run WOT for a short while and go back to idling it will run ok anywhere from 15 sec to 1 minute ... then stalls and may be hard to start afterwards. (normally start on first pull) problem...
Good day, Need to order carburator kit for my OB. there are 2 different kits depending on Model no. The ID plate is gone, Serial number is 286222. Mercury dealer tell me it's a 1997 ??? Is there a way to find the Model number ?? It's a short shaft 15 hp FORCE/by Mercury (I...
Good day,
For this 15 hp OB normal spark plugs are BP7HS Question: Could I use an appropriate hotter plug ? If so what number ? Reason for wanting to use a hotter plug is that it seems the lower cylinder plug fouls when idling for some time. thank you
this 1968 or 69 Johnson's 6 hp water pump needs the motor to be put in gear (F or R) in order to start the water flow to be activated. Is this normal ? Once primed it will pump ok until the motor is stopped for a while. Thank you.
Good day. The water impeller was the original up until a few weeks ago and was replaced by mecanic to be on the safe side. So far I could always check water coming out of the 2 exhaust outlets in the upper back part of the motor base while running wot. Now with new impeller there is plenty...
Good day. There is a micro filter prior to the gas pump. I suspect it could be partialy blocked and may cause idle stalling. The part is back-order. Question can it be cleaned and re-installed, and/or can the motor run without it ? Thank you
Good day. My OB runs great most of the time. Start fist pull, good acceleration, great wot speed. I can let it run idling gears engaged in water barrel for hours without any issue. Problem is when I run it on the river it will idle good for a short while. After I run the motor wot for...
Good day, 15 hp Force (by Mercury) Once tuned at Mercury dealer they wrote on invoice that it was a 1997 from some hidden number on engine, and I had no reason not to beleve them. Bought the OB used.
Been shopping for a prop and Iboat shows 1997 props to have 8 splines. Prop on my OB...
Wheels on my boat trailer are 480 x 12 (rather small) Have bearing buddies mounted. Is this trailer safe for long trips at highway speed ?
By long I mean 250 kilometers + return. And are all bearings the same or do I need those made for that trailer ?
Thank you all
Good day,
Checking out for new prop on Iboat and propellers for my OB are specified as 8 splines. My motor's prop is 10 splines. Bought this motor used. Dealer doing fist maintenance on it wrote 1997 on the invoice. Motor looked mint when I bought it used but with a badly repainted LU...
Good day Y'Awl
1981 Johnson 9.9 hp hit a rock at WOT on plane and messed up the LU. Repair cost to high I will shop for a used complete LU. In the meantime I would like to use the motor for fishing but dont want to run out of LU lubrification, my fishing spots are 5 miles away from boat ramp...
Good day,
Air hose connector type gas connector on Force motor started to leak at times I suspect it sucks air which probably cause occasional engine stop when idling. I presume due to trolling speed shaking. Prior to ordering original replacement part I would like to know if Merculy type...
