There are scads of unused threaded holes on engines.

BUT>>>

The fact it is a YAMAHA outdrive is enough to take the thing back for a refund.

Other than Captain Ken you are SOL on parts for thsoe things, and even he doesn't hgave a lot of them.

Thank Yamaha for hosing all the poor souls that bought their sterndrives.

Ayuh,...

If you want Yamaha Info or Parts,....

Edit the title of your thread to include the name Yamaha....

Capt. Ken is much more apt to find it that way....
