    1989 Four Winns Carrara Mercruiser Alpha 1 Bellows/Gimble Replacment

    I did mine last year gen two but basically same stuff. I made a couple self inflicted errors (shift cable and trim sender/limit) that stretched it out but did it over two weekends. If you are comfortable doing work like this its no big deal. I think the Oem kit at that time was closer to $300...

    Mercruiser 5.0 carb?

    Willing to bet your knock system is retarding . Its not the 12 v to knock module its the 8-10 v from knock module to ignition module that is what keeps it from pulling timing out. If yiu see it not advancing i would either get a inline resistor like in a older style points and supply 9 ish v to...

    Can’t get on plane

    Do you have replacement gaskets or are you trying to squeeze this in before the weekend ? If you have replacement parts strip it completely down, get a Harbor Freight ultrasonic cleaner and soak it in there. does a great job. Did you get the fuel tank cleaned out yet? no sense cleaning a carb...

    Boat bogs down after 30-90 minutes

    With thunderbolt 4 you do not put in base mode set to 8 deg at idle as ‘normal’. Basic timing light is fine I use a timing light and tach/dwell my dad bought in the late 60s …

    Can’t get on plane

    Hard to say from my keyboard... I would use something like this https://www.grainger.com/product/1XGR9?gucid=N:N:pS:paid:GGL:CSM-2293:99F1R6:20501231&gclid=EAIaIQobChMIsvTq2ODSgAMVxraGCh1tCA8BEAQYAyABEgI2evD_BwE&gclsrc=aw.ds suck out the fuel into buckets or 5 gal fuel cans. Look in fuel tank...

    Can’t get on plane

    Ya gotta get that crap out of your fuel tank and clean the fuel system and carb. There must be a layer of water in the bottom of the tank to get algae in there this tool or something like it is what is needed for the idle mix screws...

    Trim Switch Malfunction

    It is a diy possible repair - just wait until you have to do the bellows. Otherwise not worth the work IMHO.

    Trim Switch Malfunction

    There is a 7/16 " bolt head up there above the bellows and a plate that pushes the limit switch and trim sender wiring in and seals it. Yes you can do it and if you go to you tube there is a video of a guy doing just that...but you can also jumper it out inside and go boating...

    Mercruiser 5.0L two barrel Carb Leak?

    A dirty flame arrestor will cause it to run richer same as if the choke is stuck open... Does the fuel drip off the booster at idle. Some where between 1200-2000 rpm the booster will start flowing fuel. I think on my GTO with Rochester 2bbl ( older brother of the mercarb) its is about 1800 rpm...

    Trim Switch Malfunction

    If you have to use the trailer button to go up the trim limit switch on the port side of the drive is bad. They are kind of a pita to replace you can just insert a jumper wire where it comes in the boat and attaches to trim harness. Just need to remember not trim up to far while at speed...

    Mercruiser 5.0 carb?

    That has a knock sensor module is the sensor or module non functional and causing it to go into timing retard mode constantly? Unfortunately the nimrods at merc set this up to need like 9 v supply from knock module to the ignition module to keep it fro retarding timing. Below is an except from...

    2004 Chaparral Sunesta 216 engine not starting 5.0 L

    As mentioned above likely not getting fuel due to filter change. Would also verify you are getting spark. since you changed cap wouldn't be the first time a new part was defective or wire from coil got left off

    Here is a link to the stickies on pressure testing a drive https://forums.iboats.com/threads/drive-pressure-vacuum-check.230980/ input shaft seal is where the driveshaft comes into the upper drive.

    Gear lube in hull

    Yes if bellows fill up from input shaft seal leak they will end up in the bilge as the bellows gets full. There is a drain hole from bellows into the bilge. It is not a ton of work to do the input shaft seal. You need the merc spanner (or aftermarket copy) to take the big nut off the drive...

    Mercruiser 5.0 carb?

    This is not in base mode correct ? Module needs replacement then. You have the thunderbolt V ignition which is fantastic unless u need a new module. Would look for a used module on eBay. I have bought them for around $200 used. New they are expensive enough that people will replace the entire...

    Trim/Gear oil mixup

    Doubt it will make much diff or this lube even get to the outdrive, but I use a turkey baster for things like this- suck the reservoir dry. Every couple years I use it to change out my trim fluid - suck it out and refill, run it up and down, refill etc

    GM EST Distributor Kit and Mercruiser Shift Interrupt Switch

    If you get the wiring instructions for the est they will have you pick up a 12 v source like the purple igntion wire, run it through the shift interrupt and to the est distributor. When you shift out of gear and the shift interrupt switch gets closed it will send 12 v to est module to stumble...

    Mercruiser 5.0 carb?

    It has a reman label on it. Not uncommon to see rebuild shops offering older rochester 2 jets as mercarb replacements. The mercarb was what merc started making when rochester got out of the carb business in late 80 s early 90 s. They are basically siblings. Properly set up should be ok assuming...
