    Grinding alpha

    Re: Grinding alpha Holy ship wreck! You guys were dead on. This bearing is GONE. Theres a bunch of 3/16" needle bearings just floundering down in the oil. I'm lucky I didn't destroy any gears! This may also solve some of the vibration issues I've had with the motor. I'm looking at the cap...

    Grinding alpha

    Re: Grinding alpha The bearing with the red arrow, right? I'm gonna go ahead and grab part numbers for when replacement time comes. Glad to know its above the oil line... Should make it a snap. (knock on wood)

    Grinding alpha

    First of all I'm not 100% if my drive is an Alpha or MR1. but the issue is universal.... I'm finding that after a little time in idle i'm getting a periodic grinding type noise coming from what sounds like the drive or right behind the engine. It does cause the 140 to bog a little bit when it...

    Sea Sprite Bowrider

    Has anyone had any experience with the line of Sea Sprite sterndrives from the early eighties? I've tried to research it, but it seems the only Sea Sprites I find any info on are sail boats. I'd like to get some background info on my boat, so any help would be great. Thanks!

    Chattering at 3K and hot sputtery death

    Re: Chattering at 3K and hot sputtery death I agree completely. However, if I run a water hose through my manifold I don't think I should see watter flowing through the exhaust ports should I? there appears to be a large crack between the manifolds water jacket and the exhast runners. Couldn't...

    Chattering at 3K and hot sputtery death

    Re: Chattering at 2K and hot sputtery death Re: Chattering at 2K and hot sputtery death [/B][/B][/B][/B] Quick look at the plugs I pulled. Still not sure how to fix the detonation issue. I went back and tried retarding the timing a couple of degrees and that only seemed to hurt the situation...

    140 dropping oil pressure

    Ive noticed recently that the engine starts up and has good pressure up around 30-40. (sae30 oil) but once she warms up pressure will drop to around 20. After about 15-20 min of mid throttle I'll slow down to idle and pressure drops to 10 or Less. Seems awful low. Warn pump? The engines got...

    Chattering at 3K and hot sputtery death

    Hello from vacation. Took her out on the first run of the season and she ran beautifully up to 3500 RPM where I noticed a a chattering noise that ran in tune with the exhaust hum of the engine. I slowed down and the chatter quieted down. Seems sporadic. Ran RPMs back uP to 3000 and noticed...

    Ignition switch or solenoid?

    Hello y'all! Last summer my '81 Merc 140 had an issue with continuing to turn over even when I turned the key off. I ended up frying the starter, which I replaced along with the solenoid (not the one on the starter). This morning I tried to start her up and got NO response at the key, but when I...

    Carter Fuel pump rebuild?

    I've got an '81 140 that USED to have a carter mechanical fuel pump on it. A couple years back I wasn't getting fuel, so in a hurry to make things work I just slapped a cheap electrical fuel pump from Oreilly's on there. Well 3 years later I've noticed that that little electrical pump doesn't...

    81 Merc 140 stops at WOT

    Its that time again. And I'm addressing an issue I had at the end of the summer. When I'm cruising at WOT, for no apparent reason the engine will suddenly rev up and forward motion will just stop. -Almost like my prop fell off, but the engine doesn't die or anything. So I'll pull the throttle...

    Lower unit oil green?

    Hey y'all! My vacation has been interupted by an over heating motor. I change the thermostat and that helped for a second, but taxi'n on out of the cove it started over heating again. So now I'm going to attempt my first impeller change. Any advise? It's a merc 140 with the MC1 drive (1981)...

    Voltage at (-) side of coil?

    Ok so after a rough run of luck with my ignition I've got good spark again but she just won't quite start. I ran a few tests at coil and found that w/ the ig on but not running I've got 12v, when I crank I've got 12v, and I have 12v on the (-) side ofthe coil too. Normal? Cause???

    3 requirements for proper ignition (140)

    Good morning everyone! HOpe your 4th of July was great. Mine was dry, as my boat sat on the trailer rather than the blue waters of my local lake. The problem? No ignition. I didn't have a very good spark, which led me to believe the coil was weak (the old one was leaking oil from inside the...

    Tilt Trim Diagrams

    Hello, I was wondering if anyone knew where I could find some good exploded diagrams of the Alpha 1 (2 solenoid) tilt/trim Valve body that's used in the '81 Mercruiser 140. I took mine apart for a good cleaning and I'm not sure I've got it back together right. Also, can the pressure be adjusted...

    Mercriuiser 140 Trim Woes

    I recently went though and checked all my electircal connections and solenoids to make sure everythings in good shape. I hit the switch and hear them click, but the motor doesn't seem to be moving in either direction. I crossed the solenoid points to see if they were fried, but got the same...
