    Replacing Impeller on 6hp, 2004

    I'm attempting to replace an water pump impeller on 2004, 6HP because no water was spouting from tell tale. I can identify only three bolts that need to be removed. I removed an upward-facing bolt at the back of the lower unit, and one of two downward-facing bolts next to the anode on the...

    125HP, 1986, Exhaust Snout Falls Off

    I just lost my second exhaust snout. (FYI with the exhaust snout missing the prop ventilates with the exhaust to the point that the boat must be accelerated slowly.) When I installed the second one I made sure the bolts were tight and used lock washers. I've had the engine for several years...

    cavitation/ventilation problem

    I have a 18' trophy with a 1986 125HP Force. I've used the boat for three years and never had a cavitation/ventilation issue until last week. Last week, while attempting to get a water skier up, the boat bogged down and then began to rev up as if the prop were cavitating. I determined that...

    Conversion of 20" lower unit drive shaft to 25", 1986, 125HP force

    How difficult is it to convert a 20" lower unit to a 25"? I just purchased (stupidly) a 20" lower unit but I realize now I needed a 25" unit. I thought changing out the drive shaft would be a simple matter but now that I look at the manual, it seems complicated. Is there an easy way to do...

    Power head or Lower Unit ? 125hp, 1986

    Here?s my story: Replaced head gasket because of low pressure in lower cylinder. After changing, engine worked great. Never ran faster, although I heard a faint tapping noise, which was engine-speed related. At WOT, tapping noise was approximately 200 taps per minute. I believe the tapping...

    1986, 125HP: Carb or Electrical Problem?

    Boat stalls at idle and now is sporadic in acceleration and is not reaching top power. Boat was running fine last week. I rebuilt the carbs this spring and the engine has never run better until now . . . The engine stalls at idle. I changed the spark plugs. Didn?t help. It seemed to me...

    Two questions: 1. I'm in the middle of rebuilding the referenced carb and cannot locate the the main fuel jet -- which is Reference No. 40 in the attached drawing. When I look at the location identified in the attached drawing, I see no place for a jet (or any other component for that...

    125 HP, Carburetor Rebuild

    I?m in the midst of trying to rebuild the two carburetors on my 1987 Force 125HP and have two questions: 1. How is the bypass tube No. 51 connected to the carb (see attached diagram). I?m trying to remove it. The diagram indicates that it is inserted from the top, but it is not clear how it is...

    125 Force, 1986, reduced power

    I recently purchased a 1986 18? bayliner trophy with 125 HP, and am perplexed by recent drop in power. Boat ran fine initially, coming up to speed quickly and topping out at about 33 mph or so. Next day I took the boat out and it took awhile (30 seconds) to plane and was much slower <20mph...
