    Hydraulic trailer brake system overhaul

    A 24 foot boat towed by a Tacoma I’d say you for sure need trailer brakes that work. It’s your choice but if in salt water you would want disc brakes (stainless) but in fresh water you can use drum brakes if you prefer. I use galvanized drum surge brakes with zinc plated drums even in salt...

    Trailer Tires

    Tony I've been using Kenda Load Star bias tires and am on my third set, each set I get about 8 years from and never had a failure. I replace them when I start to small see cracks developing in between the treads. Same use as you, miminal trailering. I got them from easternmarine.com in...

    4.3L OMC Cobra Conversion From Points To Electronic Ignition

    When my original ESA went bad in 2015 I changed it out with a CDI unit which works perfect with the points; I’ve heard mixed things on the Petronix system but it’s nice to have an option. I grew up with cars with points though so changing them is not a big deal to me...

    4.3L OMC Cobra Conversion From Points To Electronic Ignition

    That's great! I'm wondering if Pertonix modified the electronics to make it plug and play.

    4.3L OMC Cobra Conversion From Points To Electronic Ignition

    So you're saying that you kept the original OMC ESA system and it works as designed with the Pertronix? Because in the past there was a wiring addition you had to add to make the ESA work using diodes, or you had to replace the ESA with one that will work with electronic igntion.

    Motor Knock

    An engine stethescope really helps with these kinds of problems. I had a similar issue when I did my top end overhaul (reman heads) 4 years ago. Heard a knocking noise that was intermittent. At the same time I had replaced the exhaust system, changing from the older OMC one piece V6 exhaust to...

    Valve Adjustment, 2004 3.0

    agreed the tricky part is determining zero lash. When I replaced the heads on my 4.3 I used the zero up and down on the pushrod method + 1 full turn. And got 160-165 compression numbers.

    1993 omc cobra doesn't want to crank

    Also, you might want to remove the spark plugs, make sure there isn't water in the cyls. That can mimic the problem you are seeing. ALWAYS check for water first, when you have a slow cranking problem preceded by "it just shut off"! If there is water in there you want it out fast and the cause...

    1st Run of the Season

    Well I think mine learned that there are easier ways to have fun, lol. The boat I gave my son some years back when he was still in high school is a 10' Walker Bay with a 2012 Suzuki DF 2.5 outboard. He loves it! Low maintenance, simple, hose it out and all good. He takes me for rides in it when...

    5.7 Volvo Penta Overheating at Idle

    OK then that's good, no leaks, for overheats at idle I'd be looking at the impeller housing itself. One time I sucked up sand and with my Cobra the impeller looked fine but the wear plate was scored and wouldn't pump as well as it should at low speeds. New impeller + wear plate and all good...

    4.3 GL-G Squeaking Noise, Please Help

    I’d take a pic of how the belt is routed and then start the engine briefly and see if it’s gone. If so then spin each accessory pulley and idler/tensioner to find the cause. An engine stethoscope is very helpful here. Could be the alternator, p/s pump, water circulating pump or even impeller...

    4.3L OMC Cobra Conversion From Points To Electronic Ignition

    Nice review of the system....by the way did you have to change your ESA module to get it to work with the electronic ignition?

    OMC Cobra 5.0 lower unit oil question

    Here’s the install of my old ‘88 Cobra as you can see it’s been used in salt water a long time, it will get painted with anti fouling paint before it goes in the water. I think the way you were thinking of connecting that crankcase vent hose is correct...

    OMC Cobra 5.0 lower unit oil question

    Great and you're welcome! Enjoy and as long as you keep up on the maintenance the Cobra should last. I just re-installed mine yesterday. I pull it off each fall and store it in the garage.

    Couple of tips for reinstalling a Cobra drive....

    I heard the first run of bellows were too small on the inside and they actually made them bigger to compensate.

    Couple of tips for reinstalling a Cobra drive....

    OK for those of you who have Cobras and maintain them yourselves....and this is for the dog clutch models 1986-1993....we know that pulling a drive is usually easy but reinstalling one can be difficult, sometimes it goes right on, sometimes it fights you....so here's what I have found helpful...
