    Alpha 1 shift rod connection issue

    My old upper gears ate it. Ordered a replacement and slapped it on a spare but good lower unit I had laying around ( I didn't want to reuse the old one for fear of metal shavings hidden in it somewhere). Any how the entire outdrive is reassembled perfectly, forward is forward, neutral is...

    Mercruiser 140 dead in water, no forward, no reverse, engine overheated thereafter

    I was stranded the other day when the above happened. I was at WOT when the boat stopped. I had suspected a bad clutch dog b4 and tried adjusting the cables to at least get forward all to no avail. I have a spare LU but I grew concerned when the boat was idling and its temp (normally at 100)...

    Hesitation/bogging down @ 1500 to 2000 rpm

    I have a 140hp mercruiser that runs great on both the low end and the high end but getting between the two can be tricky. My tac doesn't work so I'm guessing that the problem occurs between 1500 and 2000 rpm. The problem occurs when working up the throttle range. Everything will seem fine until...

    50 HP johnson wont open up

    I have a VJ50TLETB on a 20 foot pontoon. I hadn't taken it out in a few months, but did the other day with a few friends. It fired up fairly easily for having sit for a few months i was actually a bit suprised at that. Upon launching it though I was suprised at the dock when the fast idle...

    catalina 22 swing keels

    im thinking of buying a 1982 catalina 22 swing keel. I had heard from an old salt that if you cant get the keel up or down, you'll never be able to get it up or down. I would have thought if it's stuck for some reason a new pin, bushing, ball, winch and cable would without a doubt fix it. Has...

    problems with Mercruiser 5.7, IO

    Recently replaced engine with a reman Mercruiser. When engine is hot, it does not run smooth. A couple of observations: exhaust smells rich, engine runs rough and kills at low RPM and when shifting to dock, at full throttle RPM does not get above 1000.

    New lower unit slips out of gear... i think

    i own a VJ50TLETB on a 20ft toon, i put a brand new lower unit on it two months ago. Ive been having an intermitant problem with it. It doesnt do it at an idle or anywhere on the low end, but when i get it about halfway open to WOT, it may run great for a few minutes maybe an hour but...

    Motor runs great cold, once warm...not so great

    I was out on the lake in my toon with a johnson on the back. It did this to me last time i ran it, but when i get the motor running and get it good and warmed up it RPMs drop down to a rough half idle and barely runs @ WOT. It seems to go away once you let the motor cool down, (by that i mean...

    Benefits of a jack plate for my johnson

    I own a fiesta pontoon, i just put a new motor on it a johnson 50 hp. when i first mounted the motor i bolted it on on its lowest setting. i was a little dissatisfied with it as when i was running wide open a wall of water would shoot up off the transom, when i tilted the motor quite a bit of...

It has no reverse, after checking the shift rod height, it was off, its now up to spec, but reverse isn't there... it came back more than it was, but definatly clutch dog, or rev, maybe both, as it grinds, and the prop spins free in rev. I thought id just keep it goin...

    dry rack vs wet slip

    My paw has an 82 27 ft carver, it's currently dry docked, but he's curious aboiut moving it to a wet slip. It's an i/o, with raw water cooling. The boat was designed to be trailered, so i dont beleive there are any zincs on it other than the one on the outdrive. Ive put it into his head that...

    the state of my stator

    i just pulled off the flywheel on my 93 jonny 50hp to get to the bottom of my no spark on a cyl. Bad timer base according to my volt/ohmeter. But i noticed some cracks on the stator (my model is a one peice stator), they arent that big, but it makes me wonder if it's worth replacing while the...
