    No spark !!!!

    BT has you steered straight -clean and file the points set with a dwell meter once you get it running. When properly maintained points are just as good as any ignition system, but this is why they did away with points too much maintenace.

    Adding gear lube

    Thats how I fill it, up through the lube bottle with the top plug in. There is some air trapped in there somewhere as I always loose a little bottle level after using it a time or two, top it off and Im good for the summer.

    Carburator frustration

    Plenty of GM cars back in the day used them. Mid 60's pontiacs used them until the Q-jet came out. The metering rods are nice for tunability and the secondaries are essentially vacum operated as the air valve is weighted and only opens based off what the engine needs much like the q -jet, just...

    Here's the link to the Edlbrock tuning guide https://edelbrock-instructions-v1.s3.amazonaws.com/edelbrock/carb-tuning-guide.pdf If you havent worth reading the first section on how the carb works. you need to determine if your issue is with WOT or part throttle cruise as that will lead you to...

    Carburator frustration

    Fuel supply to the carb, i know you said the fuel pump was replaced but have you measured the fuel pressure while running? What dot he contents of your fuel filter look like ? what do your plugs look like In terms of reading them for mixture clues? on my 5.0 i did not have to rejet when i...

    Delco Voyager EST.... New ??

    The interrupt switch when closed during coming out of gear momentarily supplies 12 v plus to the est module in the distributor . What you mentioned is correct fro a non est merc thunderbolt system. Slight rewiring as outlined in the link i attached is required for the est system. Both work just...

    Carburator frustration

    Volvo penta used a 4 bbl intake with and adapter to neck down to a 2 bbl. i run a 1409 on my mercruiser it worked well out of the box, i just went with a larger accelerator pump nozzle . I does it idle ok ? I would check your fuel pressure should have around 5-6 psi at wot. also check your...

    Mercruiser Alpha 1 Gen 1 Project

    Definitely replace the gimbal given the rust and moisture in the grease. One other way to get water in the bellows is through the shift shaft theres seals where it pivots through the exhaust passage the top one can let water into the bellows if the big square gasket leaks .

    Fuel pressure dropping.

    How long does it take for the fuel pressure to drop to zero? One thing that hasnt been mentioned is the fuel tank vent being plugged, but this would take several minutes to start pulling a vacum on the tank. you could test this by blocking off the boat tank and hook an outboard tank to the pump...

    Hydrolocked in the parkinglot

    If you have the fin and it is not in need of replacement leave it. Having had both on PS equiped boats over the years I wouldnt swap out one for the other. If you later put a different prop on you can easily trim it to fit. Almost any higher perfromance prop than a black max will require...

    Mercruiser Alpha 1 Gen 1 Project

    As mentioned clunk going into gear is correct for a dog clutch style like on the alpha. If it clicks or doesnt fully engage that is more likely shift cable needing replacement, so replacing the drive wont help that. Moog 315 or equivalent is the correct ujoint. I would also replace the ginbal...

    How to tell what carb I need?!?

    the fact that is an alpha doesn’t matter but you may want to verify the drive Ratio on the off chance someone swapped in a 1.32 ratio off a 454 powered boat.

    How to tell what carb I need?!?

    Who ever told you that is a 2 bbl is wrong. Thatis a 4 bbl Rochester Quadrajet. good news is properly rebuilt and set up it is a very good carb, dont get fooled by the quadrajunk, quadra bog or other comments you may see. start with the basics check compression, look-at what comes out of the...

    Merc Alpha4 no longer available. What to replace it with?

    I ran an offshore ( I think they also called it vensura at one point). Worked very well, especially on holeshot for watersports. I had a fair amount of slip with it on the top end and wouldn't stay hooked up with more than 1/4 trim out. The results you outline are exactly the reasons I...

    VIDEO Help: Post Texas Freeze Leak

    With cracks like that i bet your block is toast too. Look below the manifolds on the sides of the block i suspect you will find similar cracks there. If none visible, before you put any money into any tube up or oil change items, Run it on the hose let it get good and hot. Look for water...

    Hydrolocked in the parkinglot

    Yes you likely broke the seal on the plug. i believe there are two set of passages in that part of the drive. One is cooling water through the drive and into the bellhousing and then up to the engine. The other one is the gear lube up from the lower half. Normally these passages are made by...
