    Trim Piston moving out of position

    When trimming the motor, the trim piston makes contact with a block on the swivel bracket. Under power, the piston is slipping up and over that block essentially making the trim position ineffective. We?ve tried tightening the trim cylinder housing, but it is still doing it. We recently...

    Low RPM Under Load

    When NOT in gear we can get about 5000 RPM out of the motor. Under load we can only get about 3000 RPM and that equates to about 1/2 to 3/4 normal speed. In addition, this morning when we lifted the motor to horizontal (to test run the motor in a tub) some oil leaked out of the starboard water...

    Lost Trailering Bracket

    The trailering Bracket for my 1987 Force 125 is missing. Anyone see any reason why I couldn?t just use a piece of steel rod with pins in either end instead of the standard bracket that comes with it? Or maybe a better idea for a home made replacement? or even where I could get a "inexpensive"...

    Won't go in Reverse - Things to check?

    We just finished an engine rebuild and the Motor is Running Great! We took it out several times for a total of about 6 to 8 hours so far. Then, last night, it decided it didn't want to go in reverse any more. I?m thinking I need to check the linkage, the controls for adjustment, and the lube...

    Testing on the Stand

    I've been doing some testing and tuning with the motor on the stand. My knowledge of the electrical system is still somewhat basic. To start the motor I've been jumping the starter relay from the power to the yellow wire (which I'm assuming is the ignition wire). That works great! But to...

    To Carb or Not to Carb!? a laugh or 2 4 u

    I wanted to tell you a story that might give you a good chuckle. How far should you go when working on carburetors? Well, that is a tough one to answer; but after doing some research I feel like the general consensus is to only mess with them as little as needed. Hands down Frank Acampora put...

    Bearing Cage O-ring? 87 Force 125

    Here's a minor mystery that someone may be able to clarify: Is there an O-ring for the bearing cage assembly on a '87 Force 125 "B' model? There is no reference to it in the Clymer or Seloc manuals, and I don't see it in the Crankshaft and Piston Parts diagram on Crowley Marine's site. Both...

    Ring Replacement Steps - 1987 Force 125

    I'm trying to get a handle on the procedure for replacing the rings. Mostly to decide whether I can actually get this done before the end of the season or I should just resign myself to working on it over the winter. The steps in the service manual and the clymer manual basically outline...
