    Mercruiser 3.0 LX Mechanical Fuel Pump. I am replacing with a new one is this normal?

    Clamp it in a vice. It will be stiff but should move. Doesnt need vacuum or pressure but there may be plugs in the inlet and outlet that need to be removed . If it doesn’t move return the pump.

    Mercruiser 5.7 with V6-14 TB IV module??

    Attached is a helm wiring digram. It show the purple coming off the key switch thru the kill switch, then daisy chaining through the gauges to supply the alarm and then the purple ignition wire. you are likely losing the 12 v on the purple though the multiple connections. The alarm isnt to put...

    Mercruiser 5.7 with V6-14 TB IV module??

    What is the blower alarm? All the kill switch should do is interrupt 12 v ignition circuit from key to engine harness. I’ll see if I can dig up a helm digram

    Mercruiser 305 V-8 Temp issues

    If the hose is getting stiff and the elbows and risers are hot then I would think water flow out through the exhaust is impeded and manifolds an risers will help. Did you verify that the ps cooler is not blocked? Some where there is a flow test for alpha one drives. I think like 3 -qts in 15...

    Closed Cooling System Part # 860234A1

    Why dont you post a pic of the engine and bracket where it is hitting the belt. Wonder if belt is on wrong or if someone added the seawater pump separate. Is the engine an alpha model originally as you list both alpha/bravo above ?

    What does this marking mean on this new to me outdrive?

    He is just being a wise azz... Did you ask the guy you bought it from.... Yes most likely customer name so they can put it back on a boat in the spring, which must not have happened... Did it pass a pressure test?

    Bought a Used Boat, but what is it?

    What is it - probably a bucket of chit. The more you stir it up the more it will stink. I think by the time you check the stringers, transom, and floors for rot you will wish you left it where it was sitting. As others have eluded it is a really obsolete engine and drive combo. Yes the engine...

    Mercruiser 5.7 with V6-14 TB IV module??

    Check the kill / Man overboard switch. ignition gets power off starter when cranking then switches over to purple wire when in run. Can verify by putting key in run, check for 12 v at coil positive terminal

    Mercruiser 5.7 with V6-14 TB IV module??

    if it worked before you pulled the dist most likely is it is mis timed. The V6 module will work fine to run And you don’t have to advance it more than your normal 10 degrees initial to get it to start. It will not give as much total advance but you can worry about that later. I tested my engine...

    Can't remove 5.7 vertically.

    Nice. The only thing I may suggest- something to make sure the chain can't slide off the end if the engine gets hung up on something

    4.3 Replacing exhaust manifolds - ditch nylon drain plugs?

    Have not had an issue with mine but replace the plugs every couple years. If you feel better replace them or upgrade to brass pipe thread fittings. You don’t neccesaarily need a drain plug can remove hose to winterize

    VP 4.3 GL conversion to Holley Sniper 2 efi

    I ended up with the VP kit for same reason as op, couldn’t find a kit that matched the carb number. Mikes could only give me a probably should work about their kit. the VP kit was only $25 more than mikes kit so worth it if not one can guarantee fit. i think I got if from Leaders RPM in michigan.
