    Boat trailer lights partially working

    I would take a battery and jumper cables. Connect the jumper cable ground to the battery and a good ground on the trailer. Then connect the jumper's positive to the battery and with the other end touch each of the 4 prongs on the flat 5 adapter, one at a time. While doing it, have someone...

    Can't figure out how to add trim fluid on 2007 Evinrude etec

    Why are you trying to add fluid? Is there an issue with trim? The fill screw is accessed by trimming full up and dis-engaging the trailering bracket. You should be able to trim fully down without hitting the trailering bracket.

    Help identifying?

    https://www.discount-marine-parts.com/ob_clinton_2.html If you look at the chart you will see the list of Clinton motors from 71' through 80'. In 74' the serial range for K500's began at 84,000. By 76' the serial range for K500's started at 1,220,000 Since your serial number is in the 700,000...

    What Happened here??

    I am a bit confused. Aren't those pieces of "flat bar" supposed to be there on the OMC? Looking at the parts diagrams, they seem to be what is on this motor after the retainer.... [

    What Happened here??

    4.3 OMC Cobra drive My buddy brought his boat by after it stopped working for him. Looking it over I found this! Gear lube is coming out of it. Unfortunately, he keeps boat in the water and didn't realize anything was going on until it was too late and boat stopped moving while in gear...

    How to measure the beam of my boat

    Beam is just the width of your boat, at the widest part. According to NADA Guides, a 1978 Starcraft Tristar 17' has a beam of 6' 10".

    Simplest 2 Battery Setup?

    I agree with Chris. Buy a 1/2/both/off battery switch. This is a very basic idea of the set up. One battery's positive goes to the #1 post on switch, second battery's positive goes to the #2 post on switch. Main power from motor goes to the all or both post on switch. Run a negative wire...

    Help figuring out how to fix my issue I’m having with my boat.

    First, the make and model of your motor will help everyone give you good advice. Second, when you say you trashed your other lower unit, what do you mean? You hit something? What happened to the other lower unit, as that may have caused you issues elsewhere in the motor.

    Oil Fill - Mercruiser 3.0 TKS

    No. You will not see it "full" of oil when looking in through the fill cap. That is normal.

    OMC Cobra 5.0 lower unit oil question

    So I see that you guys are correct with filling it from the middle hole. My apologies. Can I ask why that is on Cobra drives? Why can't it be filled from the bottom hole all the way up like other drives? How would filling it from the bottom hole cause an air bubble? Just trying to learn...

    Lower unit does not want to come off

    First, I think you forgot the pictures. On that motor I believe you need to remove the actual trim tab that is right above the prop. There will be a bolt up under it. That may be the missing bolt holding it up. Then you have the 4 others you mentioned. I would recommend having it in...

    mooring boat cover

    Having someone who specializes in canvas work come and measure your boat and custom make one to fit your boat. Buying one online will not fit your boat perfectly. You would also have to deal with placing all the snaps onto your boat to match up with the pre-purchased cover. It is not cheap to...

    Docking (slip) advice

    I guess it depends. Will you be in a single slip (docks on both sides) or sharing a slip (dock on one side, boat on the other)? Looking at your boat, it seems like the best idea would be to back into your slip for docking so you can easily enter, exit, and load the boat. Depending on the type...

    out drive gear lube

    If it was already full, and you said the reservoir was topped off, how did you pump another liter into the lower? Something isn't adding up. When you drained the lower the first time, did you drain it all? Like the reservoir was empty?

    Low compression in two cylinders in outboard that has been sitting

    I would say its is worth spraying some cleaner in the two cylinders that are low. Let it soak a few hours, turn the fly wheel to move the pistons a bit, spray again and let sit. Maybe you will get lucky and the rings are just stuck causing low compression. Always worth a shot.

    2020 NFL Week - 10

    I was scared picking the Vikings, but went for it. Never a good feeling knowing that Cousins is 0-9 for Monday night games. It was close. The Bears defense is good, but their offense...not so much.
