All,I recently past the 50 hour mark on my Yanmar 3JH3E and had a few questions about scheduled maintenance that I hope someone can answer:1. I changed the crankcase and marine gear oil myself, but can not do the recommended inspections and/or adjustments (valve clearance, shaft alignment, etc.) myself. I was curious as to who you have do yours. Dealer? Local mechanic? If you live in the Annapolis area can you recommend anyone?2. In the maintenance section of my manual it says that I should change the clutch lube oil and clean the clutch filter. I'm assuming that "clutch" and "marine gear" are the same thing. If so, I've changed the clutch lube oil, but have no idea where the clutch filter is. The manual doesn't point it out and I didn't see one anywhere. Does the thing really exist or is this a misprint in the manual?3. What's the deal with the marine gear dipstick? Mine only has 1 level mark on it at the very bottom. The diagram in the engine manual is so poor that I can't tell if there is supposed to more than 1. All dipsticks that I have ever seen have a low and high mark on them. Is there supposed to be more than 1 level mark on the thing? If so where is the high level mark supposed to be? 4. After changing the oil, I now have excessive vibrations at 2500 RPM which I'm pretty sure I didn't have before. I believe it's coming from the marine gear or shaft, because out of gear at 2500 the engine is remarkably smooth. I did everything according to the manual, but am wondering if I could have done something wrong that may have introduced this vibration. Any ideas? I'm wondering if it is from too much or too little oil in the marine gear, because I'm reading the dipstick wrong.5. Anyone recommend a specific oil for this engine?Thanks in advance,MartyS/V Diversion
