Bent prop shaft mount

Barbie = BBQ, oven grill sounds like an oven set to grill... . Anyway, the coupling should be as hot as you can get it, use a Barbie, BBQ, oven, oven grill, gas torch whatever you want.   

A double tapered shaft allows you to bolt on a Coupling. (A.R.E shaft) The Coupling connects to the shaft in the same way the prop is connected to the shaft.

The coupling on an ARE Shaft are easier to remove and install than an interference fit coupling, and provide a better connection than a split coupling. Both those types of coupling require a single taper shaft.

However, if any of the 3 different types of Couplings are fitted correctly the boat will perform the same way. There are no performance gains.

Ease of removal is really the only real benefit, which will be relevant if you are maintaining the boat yourself. the Shaft will need to be removed to change strut bearings, and be replaced if it bends again, or to replace the shaft seal (repacking does not require shaft removal)

However, if the shaft is properly aligned and you don't hit anything you may not need to remove the shaft for years.

I found all the parts and finally got a hold of a nautique dealer who could get it in next week. Will likely have them fix it since insurance is covering it. We'll see what they have to say.

If the prop shaft is bent and you are replacing it, many times it's easier to cut the shaft just aft of the coupling rather than trying to get the interference fit coupling off the shaft.

Good news is that insurance will cover it. Sounds like the shaft is bent too.

Do I need to pull the shaft to know the length and diameter or can i order this based on the boat model? 93 sport

Also what's the difficulty level on doing this myself?

Thanks guys, your a wealth of knowledge.

I found the strut mount is an S-19, nautique parts has it. Would I need a different mount if I do a tapered shaft? Is there a manual that has the schematic that shows the aft tranny part numbers etc?

Trying to find a shop in the middle of nowhere southern Iowa that might do this for me. Looking like I'll probably end up doing it myself or it'll probably be August before I see it on the water again.

Thanks for the replies. Very helpful.

Which manual has the schimatic of the drive shaft assembly?

I have just finished repairing my bent strut. Mine was only slightly twisted.

1. A few people said they could straighten my strut, but there was no guarantee that it would be perfectly straight, most said use no heat, straighten cold. I didn't have a press to try it myself and the cost of getting someone else to do it made the decision easy. Also, a new strut comes with bearings installed, the struts aren't that expensive especially when you factor in the cost of bearings if you straighten it. (look for the part number on the strut, Nautique Parts had mine in stock.

2. My shaft was not bent, I thought for sure it was - once its out check it before spending money on a new shaft.

3. The shaft coupling can be an issue if its interference fit, if you are doing it, consider an ARE shaft (if you need a new shaft), or split coupling replacement to make it easier.

4. My engine mounts were seized and isolators were cracked, easy fix but check your mounts before ordering parts as its tough to align shaft when you cant move the mounts. Isolators are cheap and should be replaced if you have remove the mounts to free them up. Skidim has all the parts.

5. There should be no issue with the shaft log, it has no bearings and does not support the shaft.

Up to you whether you change the prop, but I would get it checked if you keep it.

My boat insurance covered the repair costs, check your insurance.

Need some repair advice.

Let a friend borrow my 93 sport. He hit the dredge line running across the lake. Bent the prop shaft mount. I have not seen it in person yet, only the attached pictures. Looks like the prop shaft mount is bent, not sure about shaft. Hull appears to to not have been damaged.

Having never messed with much behind the tranny. Couple questions.
- where do I find schematic and parts for that shaft mount and any bushings or bearings within? Looks like there is something plastic hanging off the forward end.

- is there a bearing or bushing through the Hull?

- do you think that prop mount can be straightened if heated.

Other suggestions?

Thanks for any help.
