2006 28TE Prop Shaft Diameter

[dblyth]

Looking for some input on the stock/optimum shaft diameter for a 2006 28TE with a Yanmar 6LPA 315HP engine.

The boat in question is for sale and I'm in discussions with the seller. I had them send over all of the maintenance records and they highlighted that the prop shaft was replaced with 1 3/8". My mechanic thinks that prop is undersized for that engine and should be 1 1/2" minimum. He can't check it with his machine shop until Monday but I had set up an initial viewing for tomorrow morning and hoping to avoid the trip if this turns out to be an issue.

Any thoughts/guidance from past/current 28TE owners would be most appreciated.

my prop shaft is 1.5" in diameter, no idea why someone would down size to 1 - 3/8", but I am not a mechanic by any means............

Mine is 1.5" in diameter as well.

Thanks for your input gents - machine shop also said it should be 1 1/2".

It's odd that the shaft would be 1 3/8". It could be a measuring error.

I spoke with the owner yesterday - turns out it was an error on the invoice from the yard that replaced the shaft and they incorrectly put down 1 3/8". He ended up putting a micrometer on it to confirm it's a 1 1/2".

Dblyth, glad that got sorted out. Thanks for circling back around.
