I have a mercury optimax 90hp 2010 model. wanted to go down in pitch so I bought a new prop. went to change it today and took my old prop off, I tried to get the flo torq hub out
to put in the new prop and I cant get it out. manual shows one piece sliding out the front and one piece sliding out the back ??? am I missing something ??? tried tapping with piece of wood dowel no luck. does it come apart some other way ?? is it seized ?? need any help I can get. any thoughts BARNACLE BILL ???
thanks
The brass splined part drives out towards you as you are looking at the prop on the motor. The plastic part drives out away from you as you are looking at it on the motor. Drive the brass part out first, then the plastic part.
I tried driving it out with a wood dowel no luck, didn't want to use anything metal and burr up the brass. stuck a screwdriver in backwards so plastic handle caught on brass and beat the #^&% out of it. it wont budge???
Try a little PB Blaster.
There is about 6 different versions of the flo torq hub. This is the only one I'm familiar with and as you can see there isn't much to it.
Mercury Flo-Torq II Hub Kit
You might try soaking it with PB Blaster, then run it down to your local NAPA and ask them to press it out. When you reinstall, use lots of grease!
What pitch are you going down to? I have a 19 P for a 90 merc. Looking for a 17.
I've got 2 Mercury props 13 3/4 x 15, and a 13 1/4 x 17 I'd like to sell. They are like brand new and I want $80.00 a piece for them. They are flo torque hub props, but I only have 1 complete hub kit for an extra $18.00.
I'm at 13 X 21 now, wanting to go to 13 X 19. my manual says I have a flo-torq III hub. prop I was going to try will not fit my motor putting old prop back on for now.
you runnin aluminum or stainless ??? if you find one I might be interested in yours if it is in good shapeQuote:

WOT is about 5100 rpm. 5750 rpm is max for my motor, wanted to try a 19p, but I may have to go down to 17pQuote:

I'll sell you my 13 1/4 x 17 prop with the hub kit for $100 shipped if you are interested. I can send pictures of it if you like. I don't think there's a mark on it. If it doesn't work out for you, I'll return your money less any shipping costs.
yes, please send pics. I'm not sure about the hubs yet, manual says motor takes a flo-torq III hub what hub do you have ???Quote:

Okay, it's a Mercury manufactured prop, part # 7744445p 13.25 x 17p. Here's a picture of the brass spline piece part # 826074. There is another big brass washer for the back, which I have, but it's not in the picture.Attachment 60742Attachment 60743Attachment 60744Attachment 60745Attachment 60746Attachment 60747 PS, there are a couple scratches on it, but not from hitting bottom or anything.

prop looks good let me see if I can find out if hub will work on my motor, guess that is grease on inside of prop ?? mine must not have any thus why it is stuck.
I've had the prop advertised on another local board and now have an interested buyer. Haven't heard if you want the prop on not, so I'm going to offer it up the the fellow who's interested.
if you can sell it go ahead, I'm doing some research to make sure what will fit my motor.
thanks Shellback
I need a 19 for my 98' 115, trying to pull skiers with the 23 aint cutting it, let me know, thanks
