I turned the shaft with a wrench and I can not see any problems. Although the prop strike bent the prop and the torque twisted the strut, it seems like the shaft survived. Do I have to remove the shaft to use a dial indicator? I will brush up on engine alignment, the prop lapping thread and I will keep the strut bearing wet when checking the new prop and strut, Anything else?

Thanks Todd, I called them and they said it was a function of shop time and said anywhere from $85 to $120ish. They also had a pickup and delivery from my local marina (I think you went there to look at a boat in Winter Haven). I should have it back Tuesday with the bearings installed. |

It seems to me I recall $75? Maybe that's for them to install new cutlass. Either way their prices seemed fair and the turn around time was quick enough even with shipping it was reasonable enough to ship it vs drive there.

I am inclined to try this first. So leave everything in place including the shaft, and just twist it back? Failing that, what is the cost to send the old one out for repairs vs. $350 new at Skidim? |

Isn't there a prop and strut place in Tampa that all the local shops send their stuff too? Maybe Admirals?

Sooooo. I hit some stumps and the strut is bent. I have the prop off and at Rob's shop, Can I get a jack from the trailer frame to the strut and apply pressure? If that does not work, can I ship the strut somewhere to have it straightened? I still don't know if the shaft is true or not.

Dropped the strut off at Hale Propeller in Old Saybrook, CT. Based on what I saw on the shelf, I hope their equipment works on "1"! There were bent struts that I doubt I could lift! Will report back. Dan

My first choice is to get the pro to straighten the strut out. I'll report back whether successful or not to find "a guy". If not, I'll give it a try. Does the forum's senior engineer (Peter) recommend heat? I could get the whole casting to 500 in the oven. Otherwise its a torch. Not sure if it much matters, its a big chunk of metal!

This: Leave it in place and twist it back. Its easier than many think. Because of my boating venue I have become quite proficient at the process. I use a 15" crescent wrench and cheater pipe. But if I had an old shaft it would be my first choice. Put a new bearing in it and twist it back until the shaft is perfectly centered. (cold). |

It takes a lot more force than you think to move the metal. Let the pro's do it.

Just my 2 cents.......... I never tried straightening the strut myself after a friend drove the 88' too close to shore and bent it, the prop and the shaft after trying to grind a stump with my prop. years ago. I just bought a new pricey one and replaced it and the shaft and had the prop refurbished. ....... I bent the strut and prop on the 72 last summer and sent both struts to Delta Props. They were able to straighten both and installed a new cutless bearing ( at no cost as I pushed the old ones out). They didn't charge me much to do it and I was back on the water in the 72 in 2 weeks. That's why we all need 2 CC's....Ya gotta have a spare!

The old prop shaft could work as a 60 inch bar to bend your strut. Good Luck

I can see the twist in the casting. It is clearly damaged. I hit a rock last year. I got the prop fixed but it was not quite right since. Seems to be getting worse, Probably the bearing wearing. Dan

Sounds like it could have been a misalignment problem

Dan,
Gary has a very valid point regarding how the strut was mounted. Take a real close look at it before condemning the strut. If it is bent/twisted, give the straightening it yourself a try. I've known guys who have straightened them while they were still attached to the hull!! A big 48" pipe wrench and a cheater pipe! Not something I would recommend but it's been done. |

Can you see the bend or is it measurable? Could it be that it wasn't mounted 90* to the bottom?

Hey folks,
1981 ski nautique I removed my propeller shaft today, the new ARE is being shipped. Found my strut has a pretty good twist. Bearing worn on opposite sides front to back. I am going to look around for a pro to straighten but has anyone been sucessful in fixing a strut at home? I've got a big vice, the old shaft, and some heat...seems like this might be something that could be done. If someone has one laying around let me know. After the cost of the shaft, my wife is going to be less than thrilled about another $500 for a new strut ( if even available). Thanks, Dan |
