    1969--85hp Starflite, model 85993E possible carb swap?

    Mid range and idle are rough, WOT is very good though. I previously had a sticky timer base due me misrouting one of the points wires. And i put in new L20V spark plugs. The original manual says L19V plugs. I will recheck compressions today.

    1969--85hp Starflite, model 85993E possible carb swap?

    Are the carbs for the newer mid 70's 85hp that don't have idle/slow speed mixture screws interchangeable with earlier models? Where the carbs with fixed mixture less troublesome? Whats the correct/recommended spark plugs for the 1969 85hp?

    1969 85hp Evinrude charging system/ Over charging!

    Thanks! I was hoping that was the p/n 173640 voltage regulator. Any problem with installing the 173640 regulator or the CDI 193-3408 regulator?

    1969 85hp Evinrude charging system/ Over charging!

    The rectifier was replaced recently with a nos part because of crumbling insulation on the original. I have a new group 27 battery in the boat. I have not done a resistance test on the stator yet. I added the volt meter this year because i was concerned about not knowing the charge state of the...

    1969 85hp Evinrude charging system/ Over charging!

    I am well aware of what high voltages due to electronics, thats one reason for my astonishment of why they were designed without out a voltage regulator. I have read other threads on this site and others about a voltage regulator marketed by BRP in the past. I attached a picture that i believe...

    1969 85hp Evinrude charging system/ Over charging!

    Thanks for the suggestions and i will double check my connections. the only load on the system is recharging the battery and a volt meter, unless i turn on the nav. lights.

    1969 85hp Evinrude charging system/ Over charging!

    I think the regulator on my 1970 parts is the p/n 173640 regulator that was released to add a regulator to these engines.

    1969 85hp Evinrude charging system/ Over charging!

    Why in the heck would Evinrude design it like that? Especially when they must of know a high voltage like that isn't good for the CDI box. I have parts from a 1970 85hp, model 85093D and that has a voltage regulator on it

    1969 85hp Evinrude charging system/ Over charging!

    !969 85hp Starflite/ model 85993. I was out briefly on the water and volt meter indicted 13.5 to 14volts but the jumped to 16.5+volts. Idled back to the pier and out of the water. I had previously replaced the rectifier with a nos part due to the wire insulation falling off. What actually...

    Recommended wood for trailer bunks?

    Is there any type of wood thats better to use for bunks? Of course they will be covered in a carpet and the boat only used in fresh water! (Fiberglass boat)

    Opinions on life expectancy of a fiberglass boat?

    I have a 1968 Glasspar Avalon 15.5ft. I purchased this from a friend whose father bought it new, so i have history on it! It never spend the night on the water, it was aways in the garage at the end of the day. It was basically a time capsule! The only problem i encountered with is it never had...

    Fuel for older Evinrude/ Johnson

    I know i can get ethanol free fuel at my local airport and a few gas stations 20mins away! But that wasn't my question as to what you prefer! The question was in general, will older outboards handle the 10% ethanol gas

    Fuel for older Evinrude/ Johnson

    My oldest boat is a 1968 glaspar with a 69 evinrude 85hp, I had the fuel tank out last year and had a radiator shop clean it out. 2nd boat is a 16ft lund with a 1978 johnson 25hp., that i believe i may have already run some 10% fuel with amsoil 50:1 and some star-tron additive

    Fuel for older Evinrude/ Johnson

    Will older evinrude and johnson outboards handle a 10% alcohol fuel/ oil mix? By older i mean pre 1980. Trying to find fuel without alcohol in it is getting very difficult.

    1969 85hp Starflite, ignition system change???

    I made a new set of solid core spark plug wires for this engine, but had to reuse the boots that go on the distributor cap. Got a new CDI electronics amplifier and coil. I was able to see at least a spark jump a 1/2" at the coil wire. Put everything back together and cranked and checked for...
