Hey have subaru generator with tapered shaft that I may put on a surface drive if there is a way to convert/adapt to a straight shaft. Thanks in advance.

The only thing I have seen on here, the guy pulled the shaft, and had it welded up, then cut to be a straight shaft. Seems to me like the cheapest/ easiest thing to do.

Yea he had a good machinists buddy

I remember seeing an adapter that can convert a tapered to a straight. It basically slides over the shaft and is held in place with the bolt at the end of the crankshaft and uses the existing keyway.

similar to this. Just need to find your correct size.

As stated i opted to pull my shaft and have it machined.
The best option is a new crank for $6-800,but at that price i could find a similar engine used with the standard crank already in it.
So 2 other options.....gamble on that cheap taper adaptor,or machine shop.
Id pass on the adapter,to me it has failure written all over it.
On a gokart application....id gamble with it.but for a boat i may take on a 10 mile trip into marsh.....no gambling for me.
Just my opinion.

Dat be it!! ^^

It looks damn good too

Thanx....best option in my opinion,machine shop woulda charged around $100 to do that job.
Made a new gasket for base.

Machine shop rates must be pretty low in some areas. Up here that would be the first hour of labor.

$85-100 per hour average in houma,1 hr minimum....didnt take long.
