    I think I need a fuel pump

    Boat is an '87 with a 3.0 Cobra drive. Hit the lake yesterday & at first ran at no wake speed. I then throttled up, engine ran fine for a couple minutes, then quit & wouldn't restart. Got towed in. I removed the flame arrestor & had someone move the throttle & I saw that the carb wasen't getting...

    OMC 3.0 Cobra seal

    Ok, you Cobra gurus, I need your advise. I just pulled the gimgal bearing on my Cobra to replace it. In the process, I ruined the grease seal behind the bearing. I called the dealer & it'll be a week to get a replacement. What I'm wondering is, can I just pull the seal & not replace it? I don't...

    Use of muffs to winterize

    I seem to have gotten into a bit of a disagreement with another poster on whether or not it is a good idea to use muffs when winterizing an i/o engine. I advised another member in the Boats Topics forum not to do it. I think it's a bad idea because if it's not done correctly a cracked block can...

    Electrical problem on 3.0 OMC

    When wiring up a new oil pressure gauge I inaverdently shorted a wire to the ignition switch which tripped the main breaker. I reset the breaker but I still have no power to starter, gauges or trim & tilt. Blower & bilge pump are ok. I checked the 50 amp fuses & both are good. Could the breaker...

    Gear oil foaming?

    I have an 87 cobra 3.0. Yesterday I fired it up for the 1st time this season. Gear oil was fresh as I changed it when I winterized the boat last fall. The boat started right up, but after I let it run for a while I checked the gear oil & it looked milky. I let it sit for a while so I could run...

    Uh, oh, oil thread!

    I have an '87 3.0 & I have no idea how many hrs. are on it. Owned it since '92. I've always used straight 30w oil. Does anyone have an opinion on switching to a synthetic? Should I even bother with an engine of this vintage, or should I leave well enough alone? The engine runs great, doesn't use...

    Oil Pressure & valve train noise

    I own a 1987 Cobra with a 3.0 engine. Oil pressure at idle is about 30 p.s.i. & stays right about there even on plane. I have noticed an engine noise that seems to be coming from the valve train, like a rattling noise. The noise seems to get louder as the engine warms up to operating temp. About...

    Thread repair

    Well, I let my stepson hook up the tilt & trim cylinders for my 3.0 cobra while I was at work. When he was attaching the cylinder rod, he banged on the threaded end with a hammer & screwed up the threads, so I can't attach the nut. I don't have a die to cut new threads. Anyone know a quick fix...

    Painting outdrive

    I'm getting ready to sell my boat, but the outdrive needs a paint job. Most of the paint has peeled off & is down to bare metal. Can someone give me some tips on what paint, primer to use? It's an OMC Cobra. Where can I find paint that will match the original color? Thanx.

    Getting ready to sell

    I have an '87 Starcraft Medalist, 19 ftr. that I'm getting ready to sell. The boat is in fine shape, except for some cosmetic issues which i'll take care of. Problem is, it's powered by a 3.0 0MC Cobra. The engine & drive have no major issues, in face it fired right up the first time this season...

    3.0 omc noise from lower unit

    Boat is an '87 with a 3.0 omc cobra. Last fall when I was winterizing it I could hear a knocking noise coming from the lower unit. What's strange is, while standing next to the boat, I couldn't hear anything, but from say 20 ft. i could hear the knocking. Gear oil was up to full level. Last...

    Winter boat cover

    Just bought a new blue tarp to use when I cover up my boat for the winter. We get a lot of snow around here & I'm wondering what u guys do to avoid having the cover collapse under snow loads. Usually, I just prop some 2x4's under the cover to raise it up but it always seem to cave in where the...

    Noisy lifters

    Boat is powered by a 3.0 GM. I have noticed that the lifters are starting to emit a noticable tapping sound. The tapping seems to decrease as the engine reaches operating temp. The oil is clean & I have always changed it & the filter at least once a season, depending on usage. Other than the...

    Here we go again........can't get cobra l/u back on

    I replaced gimbal bearing, u-joints, & u-joint bellows. I checked the alignment & the tool slides in with little difficulty. I fought with this thing today in 90 deg. heat for 3 hrs., then finally gave up in total disgust. I have tried the screwdriver trick, brute force, bumping the engine, etc...

    Question on gimbal bearing installation

    I'm in the process of installing a new gimbal bearing on my 3.0 cobra. I have the new bearing in & seated. However when I greased the bearing I don't seem to be getting any of the grease coming out of the actual bearing, {the part that spins}. The grease is coming out around the bore. Shouldn't...

    Need help with Omc Cobra

    Boat is an '87 with a 3.0 cobra. Took boat out yesterday and heard growling noise in transom area. I suspected the gimbal bearing, so today I pulled the l/u. Bellows was full of water, probably ruining gimbal bearing. But my main concern is the condition that I found the u-joint bellows in. In...

    Carlisle/Goodyear

    I've been looking into purchasing a couple trailer tires. Because of what I've heard I've been trying to avoid Carlisle's. When I talked to a local tire dealer yesterday he told me that Carlisle bought the Goodyear line of trailer tires. He told me he has Goodyears, & I quote, he said, "if u buy...
