Strut, Shaft, Shaft Log, Engine Alignment

[minaret]

Definitely needed alignment. But please, all of you, stop calling it a cutlass bearing. It's a cut-less bearing. As in it won't cut a groove in your shaft. Longtime boatyard pet peeve. Mariners love anything that sounds piratey. I suppose it can't be helped...

Check alignment after boat has been in water a couple of days.

Many times I have seen the shaft a little off center as it exits boat....this is not unusual.

If you have a flexible hull it'll have to be done in the water. My shaft will move off center 1/16" after it's put in the water.

As long as the shaft is aligned and not hitting anything when at full speed, then you're good to go. Cosmetics mean nothing!

I don't know how that could have happen. Anybody ever disassembled a ZF10M?

Not to hi-jack this thread, but I rebuilt my own HBW-10-3, which I believe is the same thing.
600 hours in two years is a lot of running on a pleasure craft transmission. And if one doesn't make sure the indents and ball checks are good and in place it can cause excessive wear on other parts. IAW if the linkage is out of adjustment.

Thanks for the Info. Didn't mean to hi-Jack the thread but could not find a way to post my own. You all have been very helpful.

Goto the top of the page and click on the "Forums" tab, and then on the subject you want to post in. The upper LH corner of the subject you'll see a button that says "New Thread", click there and enter the title and below, the comments.

Too late 4 OP but anyone having problems with driveline should check motormounts. If even one is worn out if it's not replaced (better to change all at same time) the money spent on realignment will be wasted and won't last. Age is a culprit but also the conditions (lot of pounding) the boat has been used in will contribute to mount failure.

Potato...................pa-tah-to

Cut-less is a trademarked name (Duramax)

Just like Sawzall.........Milwaukee

Black and Decker does not make Sawzalls....they make reciprocating saws
I was corrected by a family member who works at International Headquarters for
Stanley-Black and Decker

most of the folks i have sailed with and seen with off balance shaft --is due to motor mount issues. would eb a good idea to check this before the shaft tube is worn thru.
other causes i have seen were propeller damage, making the prop off balance.

funny how the box says "cutlass bearing" on it...., as does the catalogue.....

The real question is, how did the strut get so far out of alignment with the shaft tube (assuming your shaft is straight) and will this continue to change?

If this question is not answered first then any sort of alignment is pointless since this alignment may continue to change.
