    Merc 3.0 no start, just a click

    I think you nailed the starter to the wall. SOMETIMES you can give the starter a little tap with a hammer, screwdriver butt, etc and it will dislodge from whatever is hanging it up (you could try it just for piece of mind though it doesn't change the fact that it sounds like your starter is kaput)

    Sea Sprite Hull Flex

    Hello folks, I took the ol ‘81 Sea Sprite out on a nice long run over the weekend over some fairly rough water and it felt like the whole thing was coming apart around me. The dash boards flexed so much that the center windshield fell in and got wedged between the port and starboard wind...

    140 getting warm at 3K

    Took my boat out today for its first trip in nearly 3 years. All went pretty well as it idled out of the cove at 1500 RPM sounding very healthy. Good temp, oil pres, voltage etc. I decided to goose it to about 3K and it was doing fine then suddenly began gaining RPMs on its own. -slowly, nothing...

    Shift rod sitting too low

    Good morning sailors! I've got my boat just about ready for her first summer outing, but I'm trying to solve one more mystery. I had replaced the lower shift cable and bellows and put everything back together and it seemed to be working well EXCEPT that it was getting stuck in forward gear. Come...

    Is an old drive worth the repairs

    1981 SeaSprite 140 with the original (I believe) pre-alpha still hanging on the transom. Pulled it yesterday to replace a damaged lower shift cable and the whole drive bellows was full of gear oil. My immediate assumption is that the upper driveshaft seal finally gave up. It looks like I can...

    Electronic ignition Delco Est

    Good afternoon boys and girls! The time has come to replace my distributor (worn bushings) and rather than just replace ive decided to upgrade. I purchased a gently used electronic distributor that I thought would come with the wiring harness and coil, but it did not... No biggie, I can make my...

    140 won’t idle correctly

    Good morning! I’ve been running down ignition gremlins and now that I’ve got this licked it seems there could be a fuel problem. (Long story made longer) this engine had to have a new crank and #2 piston due to spinning a bearing.So it’s been blown Apart and back together, timing set to 6* and...

    timing bouncing around

    1981 Mercruiser 140, timing is bouncing around all over the place when trying to set it. It’s not by much but I need to have it at six and it will fluctuate up to 12 BTDC then back to six. Idle is approximately 900-1000 RPM. So I almost wonder if that’s too high to set it initially.... also...

    Vacuum advance for 140?

    I recently found myself in need of a new distributor and found a part number cross reference that directed me to one with a vacuum advance. Now mine (1981) doesn’t have vacuum advance but I guess I could see the benefit of adding it. Has this been tried? Any thoughts on why it would be a bad...

    rebuilt 140 doesn’t like to idle

    Rebuilt ‘81 140 doesnt like to start without really feathering the idle. -even if I’ve just shut it off, it won’t restart without pumping the throttle than holding it down to bring it up to 14-1600 RPM. After About 20-30 seconds of that I can bring it down to 1000 rpm and it’ll hang out there...

    Will a transducer for a Super 60 work on Humminbird Wide Eye?

    The whole question is in the title.... I'm trying to find out if the old (but still working transducer from the old Humminbird Super Sixty will work with a 2007 Humminbird Wide Eye. I don't know what to look for or check or what kind of wiring adaptations I might have to make but I figured...

    140 won’t turn over

    Good afternoon everyone. Thought my project was coming to an end; had the bottom end and bearings replaced on my 140 over the winter, everything is back together, and engine was test fired for just a brief minute to make sure everything was in order before putting in back in the boat. But now...

    Lots of ignition/starter/alternator questions

    I'm going to enclose plenty of pictures here soon so you'll see what I see. I'm trying to make sure all my Ts are crossed and i(s) dotted.... So the alternator I've got is a GM unit. The 4 wire system is now a 3. I've got the red and orange wires spliced together. That just leaves my ground and...

    140 RUNNING (& DYING & SCREECHING) AGAIN

    Hello boys and girls. After a long out of body experience my 140 is back in the hull where it belongs. Had everything realigned and reconnected by a real live boat mechanic and it was probably the easiest $500 I ever spent. Got a new Optima battery yesterday and went to fire it up for the first...

    TOWING WITH A COVER

    I just purchased a Covermate cover last night and paid right @ $200 for it. This is the most I've paid for a cover as I usually go for the $70 jobs at academy and then have to replace them every 2 years. (3 if I duct tape them back together) The killer is always towing. Even for a short jaunt 10...

    Oil leak at front crank?

    Looks like I've got a nasty oil leak from just behind the harmonic balancer. I'm guessing this is the front crank seal and I'll need to pull the balancer but I'm having trouble figuring out the part number for this seal. Anything I need to be aware of when doing this?

    Bench testing 140 No Start

    I just finished freshening up my '81 merc. 140. reworked head, valves, rebuilt carb, new oil pump. I stabbed the distributor back in and set time to TDC. I've got spark when starting because I shocked the hell out of myself trying to test it.... But the engine seems to only want to fire while...

    140 fuel pump orientation

    I recently tore down my '81 140 top to bottom to reseal it and upgrade the head. But now that it's reassembly time I've had an epiphany. I remember having the fuel pump installed with the filter cap facing up. But it seems to me every other iteration of this style of pump on other chevy engines...

    Trim pump gets hot, clicks, smokes

    Happy 4th everyone! Got an issue with my trim pump. Was having a problem with down solenoid grounding out so replaced and now the motor won't go up or down. I've checked all the wiring diagrams and its hooked in correctly. But rather I hit the switch or arc the solenoid posts it will struggle to...
