Guru's.I own a 1978 inline 6 90hp that I rebuilt and it runs like a champ.I am real curious, according to spec's this motor is supposed to run W0T 4500 to 5000 rpm.I have read alot of information on inlines 6's running past the RPM range that Mercury suggests...

    I need a little edjumacation on Mercury engines

    Just curious!!! Is there any special reason why Mercury kept the rpms down (4500-5000) on a 78 inline 6 90hp. Most inline 6's all run in the mid 5000 rpm? Seems kinda odd that this is the only model that I am aware of that runs in this rpm range.Hell even my 850 runs in the mid 5000 rpm's well...

    1978 Mercury inline 6 90hp

    I am curious as to why the 90hp inline 6 was only rated at 4500-5000 RPM.All the other inline 6's seem to be well above the 5300RPM rating.Even my 80hp and 85 hp inline 4's are rated up tp 5300 RPM.Was this a Mercury brain fart??:D

    I have the old style tilt and trim with the three buttons.when I tilt/trim down I only need to push the down button but when I want to trim/tilt up I need to hold both the middle one and the top one.This is a royal pain trimming out cruising down the river @ 35+ MPH watching for sand banks...

    Mercury inline 6 flywheel timing decal ???

    On my inline 6 (1978) the timing decal is kinda jacked up and I have searched high and low for a replacement.I know some parts a hard to come by,but my thinking leads me to believe that someone in the world would have these still laying around. Or was this an item that wasnt even replaceable...

    78 Mercury 90hp Inline 6 carb. issue

    I ran my fresh Mercury rebuilt 1978 inline 6 this weekend and ran very nice except I used a lot of fuel 6 gallons in 1 1/2 hour. Throttling up and down cruising at various rpm's to break it in. I noticed that the carb. linkage that connects carb.1 to carb.2 and carb.3 are soaked with fuel. Which...

    Mercury inline 6 versa inline 4 ????

    I am fixing to put a 90 hp inline 6 on a 1972 15 foot trihull Starcraft that had a 80 and 85 hp inline motor on it before. The boat is rated for max 85hp.Will the added weight of an inline 6 make any great difference on the transom.I know back in the mid to late 60s Mercury made an 80hp inline 6...

    Removing 1972 Merc.800 with tilt and trim from a 1972 Starcraft?

    When removing the motor is the tilt and trim unit part of actually lifting the engine off the back of the boat.I am pretty sure I need to disconnect the hydrolic cylinders.I havent found any documentation on this.I am asking because I came across another merc 800 without tilt and trim and I just...

Adjusted the Idle mix screws to 1 1/2 turns out @ approx. 800 rpm.When I shut down the motor the top carb is showing vapor coming...
