9.5 motor mounts

I just got a 9.5 and I think the motor mounts are bad. I bought it along with a parts motor. The parts motor is sturdy when I grab the flywheel and push it, but when I push on the flywheel on the working motor, it will move the engine about half an inch.

I've read from other posts that this is a difficult job and I don't feel that I'm up to it. Do you all think I will need to take this to a mechanic? What would the downsides be of operating the motor in this condition?

Re: 9.5 motor mounts

The motor is designed to move within the outer housing to reduce vibration and the mounts keep it within bounds. The motor will move around more than it should but it is not fatal.

It is not that difficult to service the mounts if the screws that hold the outer cowl are not corroded. You just need to go slowly and carefully.

Like ezeke said, its not going to destroy the motor. My buddy`s got a `69 9.5 with a broken front mount and it runs so smooth you would`nt know it unless you moved the flywheel. Get yourself a factory service manual and try it yourself if you feel that its neccesary. Many dealers won`t even work on them because at $85.00/hr, in just a short time the labor cost is more than the motors worth.

You may notice a poor idle because of the broken mount. In order for the flywheel to carry it over compression, the powerhead has to be held reasonably still.

It is a very challenging job for a novice to replace it, but it can be done. It certainly is a complex job. I have replaced so many of them that I can almost do it blindfolded. Almost but not quite.

The F_R/9.5 blindfold challenge, I'd put out cash to see it:D

Re: 9.5 motor mounts

yea, I've done a few of them myself. After you've done a few, it becomes easy. It is a bit time consuming, because there is a lot to remove, but it's not bad.

What's wrong with the parts motor?

What's wrong with the parts motor?

It's missing the top half of the carburetor. The guy said he dropped it when he was looking at it and it cracked off. He said it started before that happened, but I'm not so sure. The fuel line inside the motor is cut right near the part where it connects to the two-prong connector, and looks like it has been cut for at least a couple years. One of the spark plug wires also looks to be screwed.

Also, the little plastic thing that holds the pin that holds the prop on was shown in the pictures he posted on craigslist, but was not included. So clearly he messed with it from the time it was listed to the time I saw it.

So I'm skeptical that it's just that missing carburetor piece that's the problem. Judging by the layout inside the motor, I would believe that this motor was not treated well. My plan is to replace the aforementioned wires and fuel lines. Then I'm going to take the carburetor off of the working one and put it on that parts motor. If I can get it started and running, then I'll put a different carburetor in it and have two running motors... If not, I'll probably throw in the repair towel at that point. I feel up to replacing some fuel lines and a carburetor, but probably not up to anything harder than that.
