    Johnson 150 Idle Problems

    I have idle problems with my 2003 150, and I'm having trouble finding a solution. The difficulties arise when lowering the speed to idle in gear or out of gear. With the idle speed set at 750 or below, the idle speed will gradually lower until about 500 rpm where the engine will kill. This takes...

    Possible Damage?

    Well, I may have done something very stupid. Today I decided to clean and lubricate the cables, linkage, steering and tilt points. Without thinking, I moved the throttle control through the foward and reverse positions and to WOT. The stupid part is the shifting was done without the OB running...

    150 Johnson Gear Lube Capacity

    What is the gear lube capacity for a 2003 150 Johnson? My dealer sold me a 1 quart kit and said it was enough, but I bought a second just to be sure. <br /><br />I filled the gearcase from the bottom screw and filled until the lube dripped from the top, which amounted to 45 oz. Is this correct?

    150 Johnson stalls in Reverse

    What could cause the OB to stall in reverse, but not foward. Sometimes, if I'm very fast and lucky, I can quckly move the throttle to mid position and kept the OB from stalling. However, this is not practical or safe in most situations, and I'm worried this may damage the lower unit. Please help.

    Cape Horn Liner

    I have a new 2004 Cape Horn 17, and the floor is uneven. Using a 2x4, that I know to be straight, and laying the board along the length of the interior, there is depression forward of the scuppers that is 3/4" deep on the port side and 1/2" on the starboard side. This allows water to pond in...
