    Trim gauge

    Good to know guys, thanks for the input. Yea I've just gone by feel and sound with this one, and this is my first boat so I wasn't sure if it was nice to have but sounds like I'll just go without the gauge. Thanks!

    1984 Mercedes (freedom marine) mercruiser 3.0 120hp Question: I have a trim sensor and limiter but no gauge .. I don't even know if my boat came with a gauge..could someone have removed it and installed an engine hours gauge which does not look original? Would the sensor and limiter serve...

    85 Mercruiser 3.0 possibly bad coil??

    I appreciate that diagram man, that will for sure help later on! I ended up changing the coil last night, first crank she fired right up, I was honestly surprised how quick it started but probably cause all the fuel in the cylinders from cranking before. I appreciate the help, next step is to...

    85 Mercruiser 3.0 possibly bad coil??

    It's not the condenser, it's not dwell... AGAIN I am bypassing everything in the distributor. The coil is grounded by the points which I am eliminating from my diagnosis by creating my own ground switch. I am well aware coils get shotgun replaced all the time as a result of poor diagnosis...

    85 Mercruiser 3.0 possibly bad coil??

    ok I should be more specific.. when I say I'm grounding the negative side of the coil I'm tapping a jumper wire from the negative to a good ground.. basically mimicking the points...or am I going about this all wrong??

    85 Mercruiser 3.0 possibly bad coil??

    I'll have to check that this evening! This motor only has 80 hrs on it so I don't know that it's very likely that the distributor would be worn out.

    I have not.. but wouldn't I be bypassing all that by grounding the negative side of the coil?

    85 Mercruiser 3.0 possibly bad coil??

    Hi guys, trying to figure out why my 85 Mercedes has no/ very weak spark. Good 12v to coil + and - when points are open. With points closed (after ensuring they are clean and adjusted), coil positive drops to around 4.5v and negative shows around 1v. I have bypassed the coil negative by...

    Mercruiser 3.0 alpha one no water from telltale holes

    I havent yet but I do have an impeller, housing and seal kit on order. I will need to work at the old impeller, it doesnt want to come off, almost looks like the inside hub is seized to the shaft. Thanks for the input. I'm not sure how to check that other stuff but I suppose you're right better...

    Mercruiser 3.0 alpha one no water from telltale holes

    Dewinterizing my 83 Mercedes boat yesterday and noticed running on muffs, no water pissing out from telltales. This tells me I possibly need to replace the water pump...but, additionally when I pulled the thermostat housing the inside was rusty and I poured water directly into the engine and...
