    No spark for 3.0l mercruiser I/O

    Boat...1989 Glastron with 3.0l engine. Can't get spark. Was running great then next outing, nothing. Engine turns over, but no spark. Have replaced points (correct gap) condenser, coil and checked what I could. Where should I look next? I'm thinking solenoid. Would like to get it running myself...

    Alpha One lube question here..

    Boat..1989 Glastron 3.0l Mercruiser. My question is about the zerk fittings on the sterndrive. I found four. There's three obvious ones facing aft and one on the starboard side near the exhaust. That one is hard for me to tell if I've put enough grease in. The others show the excess no problem...

    A question about correct torque settings

    My boat is a 1989 Glastron Sierra with a 3.0l Mercruiser. Just changed the alternator belt (thanks to Don for his help!) and everything is fine except I don't know the torque settings for the front engine mount assembly screws. I checked my Clymer shop manual:facepalm: but that page is missing...

    Changing fan belt?

    My boat is a 1989 Glastron Sierra 165s with a 3.0l mercruiser. I need to change the fan belt as I am getting a black deposit on my flame arrester.

    Dwell or timing?

    Have to tune up my recently purchased 1989 Glastron Sierra with the 3.0L mercruiser engine. Have not done points and timing in years. Forgot which affects which. Does adjusting the timing affect dwell or is it the other way around? My memory tells me that adjusting the timing affects dwell but...

    Bellows and WOT questions..

    I have an '89 Glastron Sierra with a 3.0L Mercruiser I purchased in December. Pretty much everything is operating good. I'm a firm believer in two things...If it ain't broke, don't fix it and effective preventive maintenance. . I do not know if or when the bellows was last changed. It's not...

    An oil and gas question...

    I recently purchased a 1989 Glastron with a 3.0l I/O mercruiser. The previous owner used Shell Rotella 15w-40 oil in it. Is this a good oil to use for this engine? It has about 175 hrs on it. Also, how good is Sta-Bil's enthanol treatment for this rig ? The tank looks like fiberglass to me...

    Choke problems

    My 3.0l 1989 Glastron Mercruiser I/O has a stuck choke. It's probably due to lack of use by the previous owner. It is the Mercruiser carb. I was planning on using liquid wrench, carefully,to free it up. Appreciate any help before I end up making matters worse. Thanks, Phil
