    Unknown Short Circuit

    Would guess the fuse is for the tks module. Easy check for a short to ground Agree with bondo, need to troubleshoot the t bolt ignition system, there is a guide in the diy sticky top of forum page

    What rotation out drive to buy

    Curious as to your logic, joking aside alpha/bravo don't jive especially considering OP provided info regarding 1989 vintage My point is many people (including trolls) post here. Most often initial posters have a legitimate concern and irl wouldn't conceive jokes from strangers

    And install it to an alpha? 1989 vintage?

    Brand New Alpha 1 Gen 2 Outdrive - Noise when turned hard to port or starboard.

    Full down/in position creates a bend in the u joints. Same with full trim position based on trim switch setting to within spec, anywhere from roughly 20-21" between centers of the trim ram. I will say many boats I adjust limit to full spec often cavitate on plane prior to trim limit within...

    What rotation out drive to buy

    Afaik the only time merc used a counter rotated alpha was for a twin sterndrive setup unless for testing or race performance. Certainly close to zero chance a single counter rotated sterdrive package was ever marketed, but the 80's and 90's had some ideas...... There's no reason to suspect...

    Lost gearage?

    Try it, buy/borrow some props. Have fun within the limits of your setup One of the funnest boats I've ever driven is a 1987 glastron cv model with a 350 mag alpha drive Came in visually/inspected stock. Carb clean with a full tune up was achieving 45 mph very quickly with phenomenal...

    1970 181 to a 1978 181 different engine harness?

    Oof You can't disregard the aluminum casting that houses the bearing. If the bearing is that much corroded in place I'd be concerned of the integrity of the gimbal housing itself Visual inspection of the gimbal housing/bearing ought to be enough to determine worthiness of repair. I've never...

    1996 Mercruiser GenII 4.3 TBI Idle problem

    Would look at wiring harness/connections considering component replacement and visual conformation of activity Merc CDS/DDT is the original diagnostic equipment but unfortunately no longer supported by manufacturers. Diacom still utilizes testing procedures. If available this is the best...

    1996 Mercruiser GenII 4.3 TBI Idle problem

    Possible but given the intermittent nature of the issue it's not likely This spec is important but again, given the intermittent nature and based on the info provided the issue can sometimes be coaxed into occurring I'd look elsewhere first. Have you inspected/tested the IAC and associated wiring?

    RE: Issues with Mercruiser 5.0 LX 4 Barrel Carb

    Fair enough. This may have been the culprit in your case, among other things. You'll note I use the phrases "most always" and "rarely" in many of my posts. This is due to the nature of this forum, I cannot see first hand any poster's equipment. I must rely on information provided and my past...

    Looking for tips and tricks for installing Bravo transom assembly

    A transom assy swap is probably the largest scoped job on a sterndrive package that is essentially plug and play. Yes there are a lot of components in a transom assy but once together the assy itself is essentially one part save for the inner plate and associated components, steering, trim pump...

    RE: Issues with Mercruiser 5.0 LX 4 Barrel Carb

    Not a valid reason for a sticky valve. A sticky or stuck valve is most often the result of excess deposits on the valve stem/guide or an issue with the spring/adjustment Water intrusion to the combustion chamber most often caused from faulty exhaust manifold/riser will cause the temperature in...

    RE: Issues with Mercruiser 5.0 LX 4 Barrel Carb

    Okay, that proves the engine isn't sound and you can expect results that you're experiencing. A leak down test on #3 will point you in the right direction, valves or rings, maybe both. My guess is tuliped valve(s) at a minimum FYI 120 psi is a tad low for sbc, should be seeing closer to 150...

    RE: Issues with Mercruiser 5.0 LX 4 Barrel Carb

    You had the heads off and replaced the head gaskets, correct? Did you send the heads out for inspection/rebuild? Seeing as how valve lash and timing are now set proper (guessing your mechanic did this correctly) my next step would be a compression/leak down test

    1996 SeaRay 215 Express Cruiser electrical issue

    Agreed. For some reason I do recall some setups used a pur/yel off the alternator. Carbed setups are becoming rare in my world and I may be mistaken. Most focus these days is on mpi/ec engines We do know for a fact OP has incorrect wiring based on provided info. At this point most info relayed...

    1970 181 to a 1978 181 different engine harness?

    Ebay seems to be the only place for oem manuals these days. I would guess you're looking for #2 and #3 for both packages

    1970 181 to a 1978 181 different engine harness?

    Best to r and r the gimbal bearing with the transom assy installed. You don't need the motor in place but in order to properly align the new bearing you need the motor set and a proper alignment tool As far as manuals you need one, maybe two depending on serial numbers. Can't say which one for...

    1996 SeaRay 215 Express Cruiser electrical issue

    Alternator, pur/yel piggy backed the oil pressure switch for fuel pump. Actually unsure of coil (+) connection for cranking, would need wiring diagram for specific on that. I guessed on the carb setup based on provided info, t-bolt n all Agree with mike that OP is exceeding the range of...

    New intake...port for pcv and for vaccume

    Normally, factory setup on a Ford based mercruiser the pcv valve in the rocker cover is routed to the carburetor base (below the throttle plates). In your case with a new carb, it's unknown if the base has a port for the pcv valve line. Your picture shows a suitable location to connect the pcv...
