Could use a little advice on a 86 2.4

[Phil L]

Hi guys,
I am in southern NJ and have a bit of a dilema. I have a 86 2.4 200 that was supposed rebuilt by the mechanic in the marina my boat is in. This past weekend, while fishing, on the run back to the dock...something fairly catastrohic happend inside the motor. While running at 3900rpm, the motor shuttered, then acted like it lost a cylinder. As I came off plane and shut the motor off, it started sounding like metal hitting metal and almost like it was starting to bind up.
I am going to pull the powerhead off and take a look to see whats going on. Any advice you guys could give me to look for, quirks with this particular motor etc, would be appriciated. It is a chrome bore block. I have a shop manual but personally have never rebuilt a outboard motor this large....only small two cylinder ones....I do have the assistance of an uncle whos been a mechanic for 30 years but any advice or info you could give me would be appriciated.

Am hoping I can repair/rebuild without having to go the route of a reman powerhead or new motor.

Thanks,
Phil L

The first thing I would do is pull the heads and have a look see, this should give you an idea of what happened whether it seized,dropped a locator pin,broke a ring etc. etc. Those chrome motors are pretty dang tuff, from your description it doesn't sound to be too bad (I hope).:cool:

Pull the heads and have a look inside first.

Sounds like you cooked a cylinder(s). I did the same this past summer on my 88 2.4L 200. You wanna buy mine for parts? It sounded just like you described. Pull the heads and see what you got. If the piston(s) is/are damaged you will see it and should be able to get a better handle of what is going on. I decided to replace rather than rebuild. If you uncle has been a mechanic for 30 years he should be able to help you out. However if he was an auto mechanic things are alot different on an outboard. I priced out doing a rebuild and was looking at 1500+ depending on what needed to be done / extent of damage. Where in NJ are you located? I am in So Jersey as well.

Thanks for the advice so far from all....Dave the boat is located down in Cape May but I am in Brooklawn, which is near the Woodbury area. What I am planning to do is pull the powerhead off the motor and bring it home to our garage so we can work on it...

Had the same thing happen to 1 a couple of years ago. Lost a rod and scored a hole broke the front half. If you look around you can probably get it going without a lot of money. Don't jump off and go buy another powerhead cause you might have the same thing happen. Marinas and a lot of mechanics would like to make you think that you can't do the overhaul, But I've done a couple and it ain't brain surgery(it's a whole lot easier than automotive). I hope for the best but check every option before you spend the money. I was looking for a drop on reman powerhead and it was $3500 plus and I had less than $700 in mine. I had a crank from Missouri, rods & pistons from New Jersey and a block from New Mexico. Good luck.

Best advice, pull the head and turn the flywheel around by hand and see what happened to it.
