    @Jakem- before you put a new carb on did you resolve the fuel contamination issue ? You dont want to pollute a new carb with debris Would also recommend a 4 bbl if you are going to upgrade, I saw much better mid range throttle response when I went from Mercarb to Edlebrock

    Mercruiser 5.7L Major Oil Leak Underneath

    Do you have blow by on engine that may induce leaking from crank seals under load and not show when idling on the ground? First thought is rear main seal or core plug in back of block where cam goes Where was the oil on the engine when it was removed?

    4.3 dying when putting it in gear

    Disconnect the interrupt switch and put it in gear. If it is the switch it wont stall out, if it does look for other carb or ignition issues.

    Volvo Penta BB260 Ignition Coil

    If resistors were bypassed would think boat originally had points and was converted to electronic . As with other comments post a pic of what ignition system you have as it would be odd for someone to refit a Merc Tbolt to a volvo. Wondering if it is a Delco EST and OP is mixing up nomenclature?

    4.3 dying when putting it in gear

    Watch the shift plate when you shift see if it is tripping the interrupt switch. if it is take the lower shift cable off shift plate yiu should be able to shift it easily. If not pull the drive and see what is hanging it up. would find it odd to be the cable since it was just replaced, but that...

    Priming a Rebuild Engine

    I would get a scope camera and look if the retainer sleeve is still on the oil pump if it is you can probably get the drive shaft back in with some finagling and cursing … if it fell off into the pan you have to pull the motor.

    It is big enough for your application. A 5.0 engine up to 5 k rpm doesnt need much.

    fWIW looks like these came with both Holleys and Rochesters originally https://www.marineengine.com/parts/mercruiser-sterndrive-parts/888-2-bbl-ford-302-v8-19711977/3108723-and-up

    3.8 OMC replacement motors?

    Gm marine engines are essentially truck engines. Typical differences between auto and marine are camshafts, head gaskets, core plugs. the real differences are in electrical, ignition and fuel systems those are very different if you really like the boat and its in decent shape get a complete...

    Lubriplate SPO 255 and Loctite 5900

    Any assembly lube can be used, what ever is available locally will work fine. one caulk tube of 5900 will work .

    Dean's List gets another motor

    To me that is the right way of doing it, there can be no question down the road what it was machined to And the customer is accepting these measurements/tolerances. He probably learned it the hard way early on. Unfortunately getting harder to find guys like this anymore…

    Mercruiser alpha one gen 1 buzzer system

    If i recall correctly on my 1990 vintage 3.0 was engine temp and oil pressure look and see on thermostat housing and stbd side of block you would need to see both a gauge sender and switch at each location fir them to alarm.

    Glastron SX 175 Gas Smell

    To the op if it were mine id replace the sender gasket, tighten the clamps on the fill and vent hoses and see where that gets me. Yes hoses could be contributing but i wouldn’t get into them just yet.

    May not be trashed. What I did with the gas out of my GTO's rusty tank was let it settle in 5 gal buckets for a couple days, I used my Mityvac (vacuum oil changer) to suck off the top of it leaving the sediment/last couple qts in the bucket, pumped it back in new tank through a paint strainer...

    Ford 302 pinging

    Yeah that's not good. Unfortunately looks like you have rust or other contamination in the fuel tank, you need to empty tank clean it out clean the fuel lines etc and then rebuild the carb. Had this issue with my old GTO, when I actually started driving it rust was getting kicked up from old...

    Help to identify the boat year and model.

    It might- is 45 is max HP - here is a 1971 catalog - I think pg 5 has what you are looking for - 50hp and 1100 lbs capacity ... amazing how light these old star crafts were https://www.starcraftmarine.com/sites/default/files/catalogs/StarCraftRunabouts2.1971_web.pdf

    Exhaust component inspection due to slight overheating

    would take the hose off and see you should be able to take ends off and see if tubes are clogged 172 isnt hot. My boat with 160 stat runs about 170 normally. Would rule out gauge inaccuracies as Nola suggested.
