stopped by to see the boat today, i was not ale to count the teeth on the drives, as the props and the nut did not leave any the of the teeth exposed. If I get the okay to get the boat outside for a few days to work on it whats the easiest way to get those props off and what size do you think that nut is? Will fluid pour out the back?
Trying to see what drives i actually have will make it easier to know what engines they will handle and how much I will be able to beat on them. Also i am hoping someone will chime in and let me know what to do to service the drives so I know they are ready to go.

You should remove the drives and have a capable shop service them. #3 were typically regarded as good for 700 to 800 hp.

No fluid will come out by removing props. Probably a 1 7/16 nut. But with the two spline sizes there are two nut sizes as well. The smaller shaft may have 1 1/4 not sure. I big crescent should do the job.

Prop nut should be a 1 1/2" socket or wrench. No fluid will pour out when you remove the props.

It's amazing how things work out sometimes......
Indeed, I hadn't thought about that when you told me about the towing job the other day. Let us know how things work out with the storage facility Brian. - Jeff

I don't know how everyone else does it, but I use a 2 x2 or 2 x 4 to hold the prop from turning when removing the nut. You want to be careful not to damage the props. Also, make sure the prop lock washer deals have been flipped open, not sure what you will have on there. Anyone?

No prop lock tabs on SSM. If there is grease on the splines the prop should slide right off with a little "love tap" or two. If they are stuck a puller may be necessary.

My sister got a new camera so when i bring the boat over to the house (if the storage facility is able to get it out for me) I will get some pictures of everything.
I don't have a cresent that big but i might have a deep impact socket that big. If not ill have to see what i can find at our shop at work.
So do you wedge the 2x4 between the prop/ground or prop/trailer? is the nut a reverse thread or anything? i was looking at the nut and it was looking like a little rust may make getting that nut off a little difficult. I should squirt it with wd-40 right when i get it out of the storage and it should be good by the time i get home.
I have a big rubber mallet that should do the trick once i get the nut off.
I am excited to get some progress on this.

I just got home from hockey... i see that the forcast is clearing up in the area. I hit the prop nuts with wd40 last night in hopes to loosen things up before i bust them loose. Pictures to come by maybe mid day. :hurray:

I was using a 9 inch crecent but i wasnt able to hold the prop very well. The 2x4 i was using kept slipping. I might have to cut it to just the right length. I have a compressor and an impact gun that would probably break it loose. Will I damage anything?
From last night... My friend Matt was more than happy to tow the boat with his F-250
