1994 120 HP rebuild. Now I'm scared.

Re: 1994 120 HP rebuild. Now I'm scared.

The timing was set at 10 deg's BTDC at idle. I brought it back to 5 degrees. When I took it out on the water, I checked it and it was at just short of 30 degrees. I moved it back to around 30 degrees.

I noticed there were a couple of identical looking exhaust cover and exhaust plate gaskets but they all looked the same. How can I tell which ones I need to use?

I'll pull the exhaust cover off tomorrow afternoon and check again.

The gaskets are very similar. I mentioned that the bolt patterns are the same. Looks like they are close, but not exactly the same. Not 100% sure about that though. Most gaskets kits have two sets of exhaust cover and exhaust plate gaskets. One set for the early style exhaust set up and one set for the late style. Look very carefully at the exhaust plate/cover and the way it sits on the block. Pay close attention to the water passages on the exhaust cover and the block. You should be able to tell which gasket to use.

You can go to this link below and see the two different styles of exhaust gaskets. Click on the the "Exhaust Plate". Later style gasket 1989 and later is P/N 27-819024-2. Earlier style 1988 and before is P/N 27-F372154-1. Click on the "Click to view or Order" button and it will display the gaskets. Not much difference at first glance, but it does make a difference.

Hope this helps.

Hey.


You guys rock!


I needed an "024" type gasket on both sides of the exhaust plate and as it turns out, I put one on the outside (between the exhaust plate and the exhaust cover) and for some strange explainable reason, I put what looks like a "1259" gasket between the exhaust plate and the block. It looks so obvious now and they really do look nothing like each other.

Note to self "Stupid".


I put 5 cc's of 2 stroke oil in each spark plug hole. Turned the motor over by hand with the plugs out (just to try and get a bit of oil in each cylinder since I had been running it with water getting in the cylinders). Put the plugs in and went to start it and the starter wouldn't turn the motor over (it was like the battery was flat). I put about 10 cc's of pre mixed fuel into each of the cylinders and did the same. Turned it over by hand and then I cranked it over with the starter holding a rag over the spark plug holes to blow out the bit of oil I put in earlier. Put the plugs back in, primed it cranked it over for 5 seconds or so and it started. Really really smokey, obviously.

Idled really smooth, lifted the fast idle lever and the revs increased nicely. No missing, no bucking, no bogging down, no worries.

Ran it for 3 or 4 minutes in the big plastic tub, pulled the plugs, Very oily, obviously, but no water.


Once again, You guys rock.


Test it on Sunday.

Glad to hear that it was something relatively simple. Happy boating!

Took it out late last night. Ran like clockwork. Holeshot beautifully. Hard to go wot because it was blowing up a bit and prett choppy. But it didn't miss a beat. I am a happy man.
