    Baffled trying to check 3.0L timing.

    '88 3.0L breaker point distributor. Got the dwell close, and moved on to check and adjust the timing. I chalked the TDC notch in the balancer and 4 deg BTDC on the tab. I couldn't find the balancer mark with the timing light pick up on the #1 wire. This is my good neighbor charity project. The...

    Will Johnson-Evinrude props fit '88 Cobra 3.0L?

    Wrapping up my charity repair on the neighbor's boat. He asked me to buy the prop and add the cost to his parts bill. Not finding much specifically for the Cobra, but many other lower case parts like prop shaft and FWD gear set showed Evinrude 4 cyl outboards as applications. So will an...

    Another new tool! I'm an adict.

    Last year I made the first of many gaffes on the forum stating antifreeze was all the same. Wrong. I learned OAT and EG are incompatible, after I topped off my clearly marked OAT reservoir with Glycol. I finally got around to cleaning out my cooling system today. This vacuum purge and refill...

    Mercruiser 165 Gimbal Bearing Removal - First timer needing advice!

    Gimbal bearing pulls are sometimes fairly easy. Mine have always been a fight. A good three jaw slide hammer will eventually get the job done. I rigged up a plate puller to use with my slide hammer head. The plate rests on the aft face of the bell hsg over the studs. The nut winds the puller...

    Thank you iBoats Forum

    Yesterday was my 1 yr. anniversary as a member. And I'm grateful to iBoats for providing and maintaining the forum, and super grateful and appreciative to the best boating experts in the world who contribute. I've learned far more than I've contributed. My only regret is I didn't become a member...

    3.0L front mount fix

    While snugging up the hoist to remove my neighbor's rotted '88 3.0L timing cover, I noticed the front mount followed the hoist up. I wasn't surprised because of a ring of black goo around the head of one of the lags. The lags had stripped out the wood, and someone tried using black sealant to...

    Sometimes hoarding is a good thing

    Downsizing, de-cluttering is a popular trend. "If you haven't used it in two years, pitch it". Bwahaha. Good thing the wife keeps her mitts off my tools. I'm breaking out this 44 yr old dwell tach to check the ignition on that charity case '88 Cobra 3.0L I've been working on. I haven't used...

    Transducer Location

    Hope this adds some value to the thread. Mostly horse pucky luck on my part. My dealer RTV'd this external flat iron transducer to my bilge floor. Not per instructions. It should have been epoxied, but he wasn't quite ready when I picked up the boat so he winged it. Iffy signal that caused my...

    Need some general direction - for my neighbors kid

    Lou C : Homemade adjusting gage. Close enough for the girls I go out with. When the Admiral is feeling cranky, she tells me to pitch the odd and ends lumber scraps in my shop. She doesn't recognize valuable raw materials.

    Need some general direction - for my neighbors kid

    I'm getting ready to wrap up this charity project. Waiting for an O ring and a seal that were shorted in the kits. Cobra newbie mistake here. I didn't pay attention to how deep - how many turns on the 'chicken lips' shifter rod had before I removed it to pull the prop shaft and re-seal the gear...

    We tell our kids "no means no". As adults we know the limits of rules

    I'm prepped to get some hate mail on this one, but you can successfully violate the 'rules', sometime. Merc manual states if the prop shaft runout exceeds .005", replace the shaft. Same instructions I'd give if I were selling prop shafts at 400% mark up. I've successfully straightened two Merc...

    How long to pull a motor?

    If you have a garage or a sturdy gable roof car port, this may be your answer for a hoist. I glued and screwed four cross members near the peak of my truss garage. Just low enough to slide a 4x6 beam under. I shimmed the outer two supports 1/8" higher than the middle two to compensate for beam...

    Skinny water river boat - Sand and logs

    I've seen a few long tail OB boats up on the Miss river in Dubuque IA. The river is plenty deep, so I suspect they're used in stump fields and shallow lakes off the channel. Essentially an air cooled horiz shaft lawn mower motor on a 6' shaft. I don't know the max power these things come in, but...

    Gonna be a while longer before I can splash our boat.....

    Midwest flooding has cost many a lot of loss. Lucky we're just inconvenienced. But I'll still whine. We finally opened our Dubuque IA Miss river place yesterday. 19' gauge, just low enough to cross the road to get in. Pic shows 18.6' today. Nine feet above normal, seven feet above where I can...

    Necessity is the mother of invention

    Hillbilly shimming fixture Pretty confident this will work. Based on the assumption the current pinion/shaft/shims combo is correct. And I believe this is correct. The wear pattern on the FWD gear and undamaged pinion teeth is fine. This rig repeats at a .021" feeler. I'll torque the new...

    Necessity is the mother of invention

    kenny nunez You right, kinda. Not a pin hole, more like bird shot. Seems the recirc pump had been dribbling on the cover for some time and rotted it from the outside. I've got JB or some kick a*s West Marine 404 high density filler + their epoxy/resin. Excellent stuff for metal bonding. The top...

    3.0L Crankcase front cover oil seal removal

    This is a boating technical topic. Sorry for the rule stretch. the GM 3.0L covers many experts, so I'm chumming wide here. Getting ready to pull the balancer on my neighbor's 3.0L Cobra. I really, really don't want to remove the front cover...loosen oil pan, etc. I recall a past post where a...

    Necessity is the mother of invention

    I'm again invoking Scott Danforth , kenny nunez , Lou C for Cobra know-how. So far this 31 yr. old outdrive has looked very good.....until now. The propshaft pinion is at the point of catastrophic failure. I'll deliver the bad news to my neighbor when I'm finished here. I found Sierra and GLM...
