Installing a new prop?

Prussian Blue aka Permatex 230-80038 No.35

Seems to be the ticket for checking surface contact area....

Well I put the new prop on. Very easy job, it only took a few minutes. The prop puller works wonders. Thanks everyone for your help. I will be on the water Sunday to try this new 13 X 11 out.

Did you check the contact area like Bigmac and I mentioned early on in this thread?

Jay,
Did you have trouble getting the prop off your '91? I put anti-seize on the shaft before I installed it last.

NO THE 91 WAS EASY AS PIE DREW...I WAS TALKING ABOUT MY OLD 89. THE 91 CAME OFF REALLY EASY. THANKS!

Heat gun worked wonders! Heated the hub up for a couple of minutes, gave the prop puller a tug and off it came. Then used the heat gun some more to loosen some chain-link fence fittings that had siezed up... Think it might be time to buy one of my own soon.

i had to get a torch to heat my old one off...without heat my prop wouldnt even budge!! i heated it up and tapped it with hammer and it fell off into my hands


but then....

i got on here and bought a prop puller and it was easy as cake. i wish i had known about this board before then!

Yeah, Next Time You Put The New One On, Grease It Before You Put It On. That Way It Wont Stick As Bad Getting It Off Next Time If You Have To

X2.

Although I do not think this is such a problem with the splined shafts on the newer models.

2x4 and a big hammer seem to work the best for me...

I had my puller torqued down so tight I couldn't get it tighter even with a 14" pipe wrench. 4 minutes with the heat gun on the hub and that prop popped off ... loudly. Make sure the nut is still on there.

Excellent advice!!!

I tried to get mine off the other day (keyed) with a prop puller and it still wouldn't budge. I'll try heat like mentioned above. Any other pointers? Thanks.

'91 is tapered w/ keyway.
For stuck props, you can try WD40 or similar, but it's a tight fit, so won't help much.
Heat prop as a last resort, b/c Nibral is relatively soft material, but some hating of the prop with a propane or Mapp gas torch should make it expand a bit at pretty low temp. Heat evenly.
Or, after the prop puller is tensioned (nut still partially on the shaft so the prop doesn't come flying off), rap the end of the prop puller with a hammer. The vibration/impact will likely break it loose. Not too hard, the other end is connected to the transmission.

Last resort and I've never tired it, but sounds plausible if you're close to the water. Loosen nut a couple turns. Put boat in the water and nail the throttle a few times in reverse. The thrust of the prop will try to pull it off the shaft. Note if it's tapered, this could shear the key or ding up the keyway on the prop, I'd check it after each hit of the throttle myself.

I am also pulling a prop this week. Hope it goes well. Is a 1991 Prostar 190 splined or tapered??
