    Over-Temp alarm installation

    All chicks and disco balls aside looking at the specs for that kit the temp switch trips at 200 F. Not sure if that is too high for a 3.7? I was under the understanding that the 3.7 was very intolerant to even minor overheats before it spits a head gasket. Not sure if others here can confirm...

    Over-Temp alarm installation

    you dont need to buy a kit . You can make your own just take power off the ignition on circuit the two switches can be OEM merc ones to make the ground connection to the block as in attached diagram. Would just make sure the temp switch is correct for the 3.7 that is overly sensitive to over...

    Popped through the intake.

    This is odd - is the top of the coil cracked? Only things I could think of is its coming out of the coil top, the wiring harness is too close and its jumping from HT wire, or you dont have a great cap to rotor connection and the spark has no where to go- only time I saw this was disconnected by...

    yes if you want to improve planning performance yes drop in pitch. How does your current WOT rpm compare to what the engine is rated for? Is the engine in a good state of tune ?

    First time pulling an engine questions

    yes it takes about an hour if you are reasonably familiar. yes you can weld a patch over the rust hole. just completely check it out as you may have small pitting and not worth messing with it.

    Is Vessel View worth it?

    disconnect engine temp alarm switch, oil pressure alarm switch, and drive lube bottle switch test to see if it goes away. If it does reconnect one by one to see which switch is tripping it

    Problem Restarting, Idling and Acceleration when the engine is warm. Merc 140hp 3.0 Alpha 1 Gen 1.

    probably a rabbit hole. Figure out why your hot restart issue is occurring - no spark, no fuel or too much fuel. Do you get black exhaust momentarily when it does restart?

    Wideband O2 sensor install

    that's barely a bar tab in this sport.... You can use grade 5 as thats is what barr supplied me with their manifolds and elbows if you are fat at idle and mix screws do nothing would suspect your bowl level is too high or one of the floats/needle and seat is getting overcome. I wouldn't expect...

    Ol' Girl will not start now a'pre-sinking !?!😩('92 merc 5.7 alpha 1 gen 1 4bbl Quadrajet)!?! HELP!!!

    You can always easily dump a little gas down the carb to quickly confirm it is lack of gas. If there is decent spark it will run a little bit with some gas dumped down the carb.

    Problem Restarting, Idling and Acceleration when the engine is warm. Merc 140hp 3.0 Alpha 1 Gen 1.

    Yeah most likely the fuel in bowl is dribbling into manifold after shutdown and flooding it. If the choke closes and gets set this only makes it worse. You need to open the throttle wide to clear the overly rich condition. two safety related comments- is the fuel pump marine rated? Marine...
