I need to pull my props to get them scanned and my boat is in storage. I want to buy a prop puller and need to know what the clearance is between the base of the prop and the strut, also what puller would you recommend. I know the shaft is 1 1/2". Thanks for your help.

There is usually about an inch to an inch and a half between the prop and strut. I would buy the least expensive puller you can find just make sure it will fit between the end of the shaft and the rudder. Some pullers need to get to the shaft end and pull from there and may not work. Hope this helps.

I'm no help on the puller but....

Proper instalation instructions when they go back on.


-- Clean shaft end, especially taper surfaces to remove all foreign material.
-- Clean internal taper of propeller hub. Note: If lapping propellers is part of your normal propeller installation process, perform this operation at this time.
-- With key removed, install propeller on shaft. By hand, push prop onto shaft until seated on taper. With a fine point magic marker such as a Sharpie, mark the location of the forward end of the prop hub on the shaft.
-- Remove propeller.
-- Install key into keyway. Key fit should be a light press fit. Use of a nylon or brass hammer may be needed. Gently tap key into the keyway until key is seated. Ensure key bottoms out in flat section of keyway away from spooned radius at end of keyway. Remove machine screw from key.
-- Reinstall propeller. Push prop on shaft until it seats on taper. Look at front of propeller hub. The front edge of the hub should be located at the mark on the shaft made in former Step. If so, go to step -- If front edge of hub is beyond (covering) mark, go and repeat procedure.
-- If front edge of hub is not to the mark or behind the mark, double-check repeat as necessary.
-- Determine cause of problem:
(A). Make sure key is completely seated in flat section of keyway.
(B). Make sure no debris or foreign material is between key, shaft keyway and propeller hub keyway. ©. Measure keyway height, shaft keyway depth, and prop hub keyway depth. The prop shaft keyway depth, plus the prop hub keyway depth should be 0.010? to 0.015? greater than the key height.
©. If it is not, contact Tiara Technical Service for assistance. Once the cause has been determined, repeat former Steps -- Install the thinnest brass prop jam nut and tighten to propeller.
-- Tighten the jam nut. Care should be taken to ensure that torque is being applied to tighten prop shaft and not to bend shaft and deflect boat bottom. If torque applied causes the boat bottom to deflect or shaft to bend, the shaft may become slightly out of specified straightness, resulting in drive-train vibration at some speeds.
-- Install second thicker brass jam nut. The same care should be taken when tightening this jam nut.
-- Finally, install the cotter pin in the hole provided at the end of the prop shaft. It is necessary to bend only one of the legs of the pin to secure it in place.
