323 Repower

<< < (2/2)

rnebergall:
I went with the Yanmar 3YM20.  It's on the bottom end of power recommendations, but I have not experienced any issues.  I get 6 knots easily @2500 rpm.  The 3YM20 required new trans/reverse gear, of course, and redo of the mounting bed to correct for the angle.  I am not a skilled mechanic, so the marina did all the work, including new shaft, prop and dripless sealing system.  Transmission is the ZF Marine ZF15MIV.  The modifications to engine bed were very nicely done, and do not detract in any way.

They did have to cut the column between engine compartment panel and hinged door.  I really did not want that done, but as it turns out, it's no big deal.  I don't even notice the stainless fasteners holding the column in place now.  They just blend in with other elements of the interior. 

As for negatives on the 3YM20, access is awkward to the oil dip stick, oil fill and oil filter.  Have to remove the port side pegboard panel to check the oil.  It's better than the MD11c, once the pegboard panel is removed, but arranging storage so I can easily do something as vital as check the oil is a mild annoyance.

Well into my second season with the new engine, and I could not be happier.

There are certainly other good choices, including the Beta.
