    Transom replacement.

    Well, I finally decided to tear into this thing. It is a fiberglass boat from late 80s and about 90% of the transom wood was soft and rotten. I did not notice any cracks or bowing. I removed the outboard to fix the transom cap (was in really bad shape and I wanted to add a piece of aluminum )...

    Extending trim switch to engine cowel.

    '88 Force 85hp. I am tired of having to use a stick to lower/raise the engine from outside the boat during launching/loading. I would like to add another tilt/trim switch near the stern. I am no electrician but me thinks I could run in parallel and simply add another switch or would it have to...

    Black oil in pick up tube and water pump.

    Good morning folks. Yesterday I removed the lower unit to get ready for the summer, replacing impeller and noticed black oil on the inside of the water tube that goes up to the head. Upon inspecting the innards of the leg it appears the water tube can be exposed to exhuast fumes. I am going to...

    88' Force 85hp lower unit oil viscosity

    I bought some SAE 90 Quicksilver and have been running it in my lower unit this year. Only been out 3-4x so far. I dont know if it is coincidence or the oil is the cause but I have a high pitch whine when at cruising speed. Matches the frequency of my tinnitus lol. Anyways, it seems like its...

    Prop makes "clank" sound when shifting gears.

    88 bayliner Force 85hp with 17p prop. Runs fine and shift cables are in good working condition and "adjusted" as much as I know how to. Last trip out I was hearing some odd clanking sound when i shifted gears into forward. It sounds like if you tapped a big screwdriver onto a prop blade. Like...

    I am working on a 1989 Four Winns with a OMC 4.3L(v6) . I believe the outdrive is a cobra and when launching the boat last week I noticed a pretty good leak coming in through the transom area. It slows down when I gave it throttle for some odd reason but maybe thats relevant info. This is my...

    Escort trailer axle sag help.

    I bought an 88 bayliner to restore a bit and customize into a fishing boat and I found out the round single axle is sagging about a 1/4" with the boat loaded. I put a 5 foot straight edge on it. The trailer is an 88 escort and the name plate is sun baked and i cant read any of the markings so...

    '88 Force 85hp Tilt/trim oil drain and replace procedure?

    I've been wondering if the slow moving tilt is because of air in the system or just low oil. I added new oil after repairing the valve body maybe 3 years ago and havent touched it since. Its worked ok but to me it seems slow. Not sure how I could test the pump motor to rule that out. If I...

    Misfiring confusion.

    88 Force 85hp. During an outing yesterday I noticed a few things regarding misfiring and wasnt sure what to make of it. Apparently these engines dont like idling for too long because they will carbon up the spark plugs and cause running issues. With mine, it will sputter and miss like...

    Water tube connection after repairing power head adapter plate gasket.

    Force 88 85hp I decided to replace the adapter plate paper gasket after failing to fix a leak with silicone. All went well with lifting the motor and lowering. Got everything back together fine. The only thing I noticed was where the water tube comes up into the power head. At the surface of...

    88 Force 85hp Im having intermittent sneezing issues on startups after turning mixture screws out to 1 1/4. At times it will fire within a single crank and run fine. Not sure if this is relevant but the motor shakes a bit much when idling @ around 1500 rpms or about 5-6mph. Shakes the windows...

    I am not sure if this is relevant to this forum but my boat make and model commonly had the Force outboards. I have a late 80s Bayliner Capri 1700 that has a "rack and pinion" steering. I guess thats what its called. Its definitely not cable driven. My problem, although tolerable and mostly...
