My Hurth transmission has a drain, as well. Totally useless. In my stupidity, after having problems to suck out all of the old oil, I decided to use the drain. Opening it is not a big deal (an extra joint in the arm would certainly help). But putting that plug back in requires at least two extra joints or some help from a very little person (2-3 inches max). Suffice to say that it took me probably a good hour and a few choice words to put the plug back in. Note to all: don’t try it at home.
I am not overly surprised that some PO stripped the threads in the plug (probably in the transmission housing, because it is aluminium(?) and the plug is steel). He probably gave up after only 50 min.

I know because it cost me a lot of money to have the tranny pulled just so they could helicoil the drain plug that some prior idiot had stripped and "fixed" with goop. That was a very fortunate morning that I decided to check under the engine before a long passage and found a large puddle of clean oil. The drain plug is the hex head at the bottom of the transmission. http://imgur.com/5ff77e95-9f86-47d1-8054-6b2e13e2e845 Jim Watts Paradigm Shift C&C 35 Mk III Victoria, BC On 29 November 2016 at 14:12, BillBinaList via CnC-List <[email protected]> wrote: The manufacturer says single weight, either 20# or 30#. So, if you are in the Arctic circle, or somewhere so cold that heavier oil affects shifting or slippage, use straight 20#. Elsewhere, use straight 30#. https://www.yanmar.com/media/global/com/product/marinepleasure/sailBoatPropulsion/operationmanualgears/outlineKM4A-2.pdf Bill Bina On 11/29/2016 4:50 PM, Josh Muckley via CnC-List wrote: I've not come across this designator "SAE 20/30". I've seen "SAE 30" and "SAE 20" but never "SAE 20/30". I believe the other listers are probably correct that it is designating one or the other. Building on that assumption, if it makes life easier, you can use a multi weight oil since they are all the same viscosity at operating temperature. A 5w30 or 10w30 will be fine. http://themotoroilevaluator.com/members-blog/understanding-multi-viscosity-oils/#axzz4RR6Z4Xs2 Josh Muckley S/V Sea Hawk 1989 C&C 37+ Solomons, MD On Tue, Nov 29, 2016, 2:53 PM Persuasion37 via CnC-List <[email protected]> wrote: I would suspect that you would use the right weight based on operating temperature. Up here in the great white north you probably would use 20w. As you move south into warmer temperatures you may want to use 30w. Age could also play a factor.
