    75 Merc No Spark

    So I finally got everything ready today and set out to the lake. What a disaster. It was too windy and couldn't get the boat started. Wind was blowing me into the dock as I couldn't get the boat started. I thought it was flooded but when I got home I found that I had no spark. I'm...

    Switching Regulator

    I'm curious to see if anyone has replaced their standard linear voltage regulator with a switching regulator. I'm thinking about doing it but would like to scope out the feasibility and availability. My thought is that one could possibly extend the life of their stator by not generating near...

    Tilt vs. Trim

    Ok, I had glossed over this little distinction until I came accross zonaman's TT thread from yesterday. It appears that there may actually be a distinction. My only experience with PTT was on my BIL's boat i used to bower. Had a 40 force on it and you could trim it while underway to get your...

    Adding Power Trim

    Got a '75 merc 65 on a 16ft. ebbtide with manual trim. Is it feasible to think about adding power trim and if so, what is involved in that process?

    Water Pressure Question

    I have a 75 merc 650 (3cyl) and have recently replaced the baffle, outer cover, thermostat, impeller, etc. The tell tale comes off of the base before entering the block so if there as a restriction in the block, you would not know it by the tell-tale. I have been advised that on this motor...

    Advice On Some Guages

    I recently bought a '74 ebbtibe with a 650 merc. The only guage it comes with it a speedometer which works but is useless. I would like to get a tachometer, a temp guage. I have somewhat limited real estate on the dash as it's pretty small. Does anyone make a dual guage for tach and temp...

    650 LU fluid capacity

    I drained and refilled the LU on my '75 merc 650 (3cyl) this evening. It only took around 11oz before it came out of the top hole. Does this sound right. I've looked through my manuals and don't see a capacity listed. Is that good or is it necessary to let it set a bit and allow the bubbles...

    Timing Belt Alignment

    I have a '75 merc 650 (3 cyl) with distributor. The timing belt was removed and I'm 99% sure I got it back on in the correct position as I took a picture of its orientation before I removed it. Looking through my manual, I don't see instructions on how to install it so I would be 100% sure...

    Timing Mark Question

    I have a '75 merc 650 3 cylinder (as listed in my profile). I'm reading up on how to set the timing. One thing I have yet to figure out is the fixed timing mark. I have the timing marks on the flywheel but I don't see any fixed pointer or mark anywhere one can use as the indicator. My manual...

    Intake Air Filtration

    Just curious as to why none of the two strokes I see have any type of air filter? Is it deemed not necessary as when you are out on the water there is not much particulate matter in the air? Does anyone on here run any type of filter anyway?

    Poppet valve

    Can someone explain the function of the poppet valve to me. I been looking at it and don't get it. I thought I got it until I went to install the new baffle plate with the new poppet valve and realized that when you tighten the plate down, the poppet is pushed out as the stem seats into the...

    '75 Mercury 650 Triple Exhaust Cover

    I have two Merc manuals and neither one has the tightening sequence for my motor. I have the torque spec but not the sequence. Would anyone out there happen to have that?

    Loctite Type "A"

    My manual calls for type A loctite on my engine seals. I don't think type A exists any more. Anyone know what can be used as it's replacement and where I can get it?

    Gasket Surface Cleaning and Prep

    I may be making too much an issue out of this but I thought I would throw the question out there and see what comes back. I plan to be putting everything back together on my merc in near future and am at the stage where I need to clean up all the mating surfaces in prep for new gaskets. What...

    Overheating question

    I have just bought a 74 ebbtide with a 74 merc 650 (3cyl) on it. Motor looks very clean. Boat was always garage kept and I don't think it was heavily used. I finally took it out last week and it ran well. I ran it at WOT for about 5 minutes and then brought it down to idle for a bit. I...

    Any idea where this wire goes?

    This is off of my 74 Merc 650 3 cyl. If you look at the top of the switch box, you will see a cut wire. I am unclear after referring to my manual but i suspect it goes to the tilt switch. Anyone know for sure what it goes to?
