    Batteries And Charging Voltage?

    Hey guys. I looked around but didn't see an answer on here. Sorry if this is redundant.<br /><br />I have a 79' 90 HP I-6 that has been through a chain of problems though I think I've got it nailed down to the very last thing.<br /><br />I've got a CDI ignition system on it, and it seems to be...

    I6 CDI Switchbox/Coil Durability? Design Flaw?

    I don't want this to be interpreted as a slam against CDI. Everything I've heard about them has been positive. Every time I've dealt with them, they've gone above and beyond. They seem to know what they're doing. I'd still recommend them to anybody. I just have some questons about a couple...

    Ignition - Spark Into Distributor, Nothing Out!? CDI Coil Shorting Out?

    You guys are probably so tired of my questions, but you guys are my last hope in this nightmare series of events that's been going on. I took the boat out today and got all the ignition timing dialed in perfect. This is again on a 79 inline 6 90 HP. So we were out cruising around for a couple...

    I6 Distributor Timing? No Marking On Decal?

    1979 inline 6 90 HP motor. I reinstalled my distributor and went to fire it up and it fires but goes out as soon as it kicks over. I think I messed up the timing between the distributor and the belt/flywheel.<br /><br />I'm reading the book now, it says turn the arrow on the distributor towards...

    Crankcase Gasket Leak? [Pic]

    I was just cleaning up my motor (1979 I6 90HP), when I noticed what appears to be a leak from the gasket between the crankcase and the intake manifold. Everything looks more nasty in the pic than it does in reality, I could just make out deposits of gummed up 2 stroke oil - leaking fuel/air?<br...

    Mercury I6 Distributor Rebuild + Pics (56K Friendly)

    I figure I might share what I learned rebuilding my I6 distributor today (replacing the trigger/distributor housing). Maybe it'll help somebody trying to figure out how to get the thing apart, which was my biggest hangup. I'm relatively new to outboard motors, so if you see anything wrong here...

    Merc I6 Trigger Testing?

    Sorry if this question overlaps the previous two I've asked, but I'm looking for specific info on the trigger (schematics, diagrams, specs, test procedures - none of this stuff shows up in my repair manual).<br /><br />As stated before, I'm running a 78 or 79 inline 6 90 HP merc. Switchbox and...

    78-79 Merc 90 I6 Trigger Removal And Replacement?

    Does anybody know how to remove the trigger assembly from a 78-79 Merc I6? I'm assuming that you have to pull the distributor, but I can't for the life of me figure out how it comes off, and I don't want to force anything if I don't know. I have the cap off, but the rotor surely doesn't pull off...

    90HP Inline 6 Bogs Severely Under Power? Choppy Idle?

    Hello everybody, first post here at iBoats - awesome forum.<br /><br />Here's what I got - I'm running a 90HP Inline 6 of 78' or 79' vintage (Cowling decals and timing sticker look like/say 79', but some things don't appear to match up). Ever since I started her up this summer, she idles rough...
