    Terrible sound from my 9.9

    Last night I went to check on my inflatable which is powered by what I believe is a late 80's Mercury 9.9 (S/N: 0B164747). Top end runs terrific and always has although I got the motor second hand. It runs perfectly in forward but in neutral or reverse there is a terrible whirring sound, almost...

    Late 80s 9.9 - Stalls in the midrange?

    I've got a very-late 80's Mercury 9.9 that is exhibiting some odd behavior but only under mid-throttle conditions. I can start the engine wonderfully 1st pull every time, cold, hot, doesn't matter. It will troll around at idle all day with no issues and when you get up on it it runs excellent...

    Aftermarket reeds?

    Hi Guys, Just wondering if anyone can advise on the potential performance gains from putting in a set of aftermarket reeds. I am looking at poentially the Boyesen set that would match up with my 1984 Evinrude 140 crossflow. Stock and original (brass?) reeds are in there now. Thanks!

    Prop Selection Question - Searay 18' w/140hp

    Hi Guys, I just noticed my prop is slightly damaged and I'm going to replace it, I do however want to know if I can make a "better" choice, I always thought the boat should be a little faster. The boat is a 1970 SeaRay SRV190 (I believe 18.5") fibreglass and the engine is a 1984 Evinrude...

    84' 140 - Transistional Hesistation Problem

    Hi Guys, I was hoping you could lend some insight on an issue I've been experiencing pretty much "forever" with my 1984 Evinrude 140 crossflow. I rebuilt the powerhead 2 years ago and installed all new pistons into freshly machined cylinders, the compression is an even 120 on all banks as of a...

    1989 Mercury 9.9 Question

    I recently acquired a used Zodiac complete with a 1989 Mercury 9.9, it is a recoil start short shaft model. It appears to be in exceptionally great condition. Starts right up first pull and idles wonderfully. Transition to WOT is a little rough and wide open running is a little rough as well. I...

    Mercury equivalent to the "BRP Parts Catalog"?

    Random Question - Revving on the muffs

    I know personally that it is a bad idea to let an engine run beyond even 1500rpm on muffs due to lack of load and exhaust backpressure, but I was cruising through youtube a little while ago killing time at work and I just happen to stumble across a bunch of videos with people just hammering down...

    Post rebuild questions

    Hi Guys, I'm still in the process of breaking in my 84' Evinrude 140 that I rebuilt. It is running very well and is on around hour 4 of the break-in. I have two questions; 1) Do I need double oil for the entire 10 hour process? 2) Should I decarb after the first 10 hours? Seems like a lot...

    Idle and Carbon buildup question

    You may have seen my posts relating to the recent rebuild of my 1984 Evinrude 140 Crossflow v4. One of the rings let go due to carbon buildup. The more I read about carbon buildup the more I am concerned about my WOT RPM. Pre-rebuild we could get the engine around 5400-5500 with two people in...

    This engine scares the crap out of me.

    Have you ever taken on a project which seemed within your reach at first, but when you completed it you just wondered if you did everything "right" and it now seems completely over your head? That's me about now. I just completed the rebuild of the powerhead on my 1984 Evinrude 140 crossflow V4...

    I am currently rebuilding my 1984 Evinrude 140 Crossflow V4 and I have run into an issue after joining the crankcase halves. I carefully aligned all the connecting rod caps, installed new seals on the upper and lower crankcase heads and joined the two halves together using gel seal. After...

    Hi Everyone, <br /><br />This is my first post here. I'm just looking for a little bit of information. I was changing the plugs on my friends 1984 Evinrude 140 when I noticed the bottom starboard cylinder plug was wet and clean, it's getting water for sure. I loaded the cylinder with WD-40 and...
