    Advice on Gas Cap for vintage Gas Can

    Long story short - I bought an old 70s pontoon with a 93 Evinrude 2-stroke. Motor runs great but the motor was losing fuel pressure. Squeezing the bulb didn't help much. The hose is new so I switched tanks. I pulled out an old Chrysler Tote Tank that I had sitting in the shed and everything...

    What does the choke do on a Suzuki EFI??

    My 2009 Suzuki DF90A was on the fritz this weekend. I was 20 miles away from my cabin when the low voltage alarm went off. It turned over but wouldn't start, tilt/trim wouldn't work, etc. I disconnected everything from the battery, cleaned all of the connections, tightened everything, squeezed...

    To Replace Or Not Replace

    I scored an old pontoon and motor for $600. She's not much to look at, but the intent is to use this primarily as a barge across a big lake (we have no road access). The pontoon and motor went unused for 6+ years. My neighbor and I surprisingly got the 1993 Evinrude running with minimal effort...

    Pontoon Trailer Need

    I'm about to buy an old 16ft pontoon to use as a barge. I've owned several boats but this is my first foray into pontoons. I merely need to get this from the seller to my lake where it will permanently stay in the water or on shore. I need to rent a pontoon trailer to get it there. My question...

    Karavan Trailer Bearings Not Per The Owner's Manual

    As to not hijack any old threads, I am starting a new one to help others. I have a 2007 single-axle Karavan trailer with no brakes. Per the owner's manual there are three possible bearing scenarios: 1) 1-1/16" hub, 5-1/2" flange, with 1-1/16" bearings and races on the inside and outside 2)...

    Karavan Trailor Losing It's Rollers

    I've got a 2007 Karavan trailer rated for 2,200lbs. It's carrying a 16.5ft Alumacraft boat with a 90hp motor. The dry weight of those is 1,400lbs. Add in another 300-400lbs for three batteries, trolling motor, props, and gear and I assume that my rig weighs around 1,750lbs. That puts me 450lbs...

    Oil Seal removal

    How does one remove the oil seal beneath the impeller? This is on a 1960 Johnson Seahorse 5.5hp CD-17 motor. I bought a new seal, and started trying to remove the old one before running into the problems. Then I went online and saw people say that it shouldn't ever need to be replaced. That...

    How To Remove Broken Steering Bracket - 1960 Johnson 5.5hp

    I've got a 1960 Johnson Seahorse 5.5hp CD-17. The steering bracket is from an earlier model and is about to be replaced. I've got a new(used) one on the way and started to remove the old one tonight. The powerhead and lower unit are all removed. Does anyone know which bolts need to be removed to...

    Guess the Year of My Johnson (with pics)

    I just picked this Johnson Seahorse 5.5hp and was told it was a 1963. It runs decent but I will go through the carb and everything else. However, I am struggling to establish the exact year. The plate is missing from the transom bracket. The plug on the motor (bottom pic) just lists the serial...

    Screws vibrating loose

    Is there something that folks use to keep screws from vibrating loose on your boats? My fishing boat has lots of carpeted panels that are screwed into the wood subfloors. These eventually work their way out. I tried to use some Loctite that I had laying around but since it's not metal to metal...

    How Often To Replace Bearings

    I know that this one is going to get many opinions, but that's what I want to hear. How often do you completely replace your trailer wheel bearings? I've done it a few times on older trailers. My current boat came from the showroom floor in 2009 so it's got five years and gets about 5,000 miles...

    Boat Storage Contract

    I'm storing my boat in a neighbor's garage this winter. I want to draw up a simple contract that covers the major storage issues without being too extensive. Issues that I addressed so far: - Storage dates - Payment terms - Right to visit/work on boat - Expectation of basic security and...

    Connecting Bilge Float

    I installed the float and now just need to hook up the wiring. It should be easy to splice into the wiring at the pump. However, at the captain's seat the bilge is currently controlled with a 2-way rocker switch. It lights up when you turn on the bilge and goes dark when you turn it off. Of...

    Trailer Jack Grease Cap

    My new trailer jack lasted one trip up north before the grease cap came off. Something brown (fox or dinosaur) ran into the trailer while I was doing 75mph in the middle of the night. That might have knocked it out. No matter what, I need to cap the jack. Does anyone have a good suggestion...

    3hp Seahorse Wants To Run Lean

    I brought a 3hp 1957 JW-13 Seahorse back to life over the winter. I replaced the ignition, most of the lower unit, and threw in a carb rebuild. I've now run it twice in a barrel for limited periods (less than 5 minutes). It runs a little rough and doesn't run well at low or high speeds. It seems...

    We Need Boat Launch Videos

    I didn't want to hijack the other thread, but I got an idea. Someone with a video camera should sit at a few busy boat ramps with a video camera in hand. One could put together an informative "don't do this" video available online. I know that there are various videos out there showing swamped...

    Correcting Camber on a Trailer

    I've got a 2008 Karavan single axle boat trailer with a nasty positive camber. I do tow a lot of miles since it is 500 miles round trip to my cabin, and we go probably 8-10 times per season, so 4-5k miles annually. I got 1.5 seasons out of the stock Goodyear tires before they were slippery...

    Best Way To Remove Oil Seals?

    I've been tearing apart a 3hp 1957 Johnson Seahorse. I replaced the oil seal between the gear case and the drive shaft (just below the impeller). It was a real pain to remove and required lots of different attempts with various tools. I was thinking about replacing the one in the gearcase as...

    Replacing Spark Plug Wires to Coils - 1957 3hp Seahorse

    This is for a 1957 Johnson Seahorse 3hp (JW-13). One of the spark plug wires is bare to the wire in a spot. I've got the flywheel off and have new wire, but am stumped about how to swap out the wire. Do you just pull the old wire out of the coil and somehow shove the new wire into place and...

    1957 Johnson 3hp - Gas Tank Extra Parts?

    I just cleaned the piles of insulation and foam out of the 1957 Johnson 3hp (JW-13) motor that I picked up this summer for $25. When I turn the rope, the prop turns but it's completely drained of fluid - so she's about to get a complete rebuild of gaskets, etc. The first order of business was...
