Fastwin 18

[randa]

I was wondering what year it is. Model # is 15036B-07947. Got it today for free. Problem is that the guy told me that the cluth dog is probably out in forward. I went to pull the rewind and the motor is froze up. I put some Knocker loose in both cylinders to see if I can loosen it up. The million dollar question is: is it worth putting the money into it? Thanks

It would be sacrilegious of me to say its not worth fixing.

If the gearcase is siezed then no amount of oil in the cylinders will free it up. It you can't get it to shift into nuetral then you probably have gearcase issues or at least linkage problems. Remove the lower unit from the motor and then try to pull the engine over. If it pulls over the problem is in the lower unit.

If the lower unit is the problem then open it up and see what is wrong. It'll likely be cheaper to find a used replacement lower unit than to buy the gears. However, you might get lucky with eBay or your local marina.

Ditto. Separate the powerhead and LU, then check all the goodies on the powerhead, compression, spark, etc. If the lower unit is the problem, you can probably get a replacement lower for not much scratch and some patience. It's easier to go with a replacement lower than to break the pumpkin open and go through it. Done it both ways and prefer having two lowers on hand for any future problems...knock wood.

I can put the shifter into forward and reverse with ease. My problem is that that the flywheel will not turn. Thanks for the responses.

It isn't likely but if the drive shaft is frozen it can act like the power head
is set up.

Re: Fastwin 18

I suppose that the prop should be able to spin with the shifter in neutral. Correct? That baby is tight. Thanks again.

Re: Fastwin 18

Sounds like a siezed gearcase. Have you looked at the lower unit oil? Either way you need to pull the lower and find out for sure which is siezed.

Re: Fastwin 18

I had a '66 18hp that I got and it would not spin also. I assumed it was the engine but it was not. The LU was seized... And you only find that out after taking the LU off. After I put a different LU in it was a great running engine... Mind you if your prop will not turn that signifies a LU issue if you are sure it is in neutral. I'd drop the LU. It's VERY easy... I wish I got 18's for free! wow...

Re: Fastwin 18

I got the prop to spin. It will stop when you put it in forward. It will spin freely when you put it back into nuetral. The same for reverse. The motor is still froze up in the upper half though.

Re: Fastwin 18

You haven't removed the lower unit from the motor have you? It could be that the powerhead is siezed, but it could also be that the lower unit is damaged/siezed. Just because you were able to get it to shift after fiddling with it doesn't prove that the lower unit is working fine.

Re: Fastwin 18

No, you are right, I didn't take off the lower unit. Assumed wrong. Guess I will have to take it apart. Thanks for your response.

Re: Fastwin 18

What's the latest? Did you get the LU off yet? That's the sure way to tell.

Re: Fastwin 18

Looks like it will be a winter project.

Re: Fastwin 18

A winter project? It'll take you 20 min to drop the LU to determind the issue!

Re: Fastwin 18

Was going to drop the lower unit. I took the cover off for the shifter and loosened the two bolts holding the shifter rod. I took off the for(4) 1/4-20 bolts. I took off the 3/8" bolt. The lower unit dropped down about an inch and then stopped. What else do I have to do? I thought it would be an easy job but something is holding me up. I took out the drain plugs and got nothing out but rusty looking water. Thanks

Re: Fastwin 18

Well---looks like WBeaton was right. If you found nothing but rusty looking water, you've got problems. You described the correct procedure for taking off the lower unit so check and see if your shift linkage is loose. Otherwise there should be nothing holding it. With all the corrosion you must have, I suspect the shift linkage is rusted to the shift rod or something else is rusted tight. If your l.u. was full of rusty water, it probably was siezed up! It shouldn't take 15 min. to get that thing off and see if your pistons are seized, but if you have nothing but rusty water, it probably won't be worth messing with. Sorry, but at least you paid the right price!
Let us find out what happened, your lower unit should come off if the linkage is free,if it dropped 4 inches already. Maybe it'll be fixable.
Good luck,
