I have current problems and don't know if they are typical with this small diesel.
1. The throttle control does not stay in place and want to drop to slow.
- You need to adjust the friction mechanism for the throttle. It may be at the shifter or the at the motor. If it doesn't work you have to invent your own with washers, pieces of hose, etc.
2. When shifting to forward it stays in gear, but reverse you have to hold. Is this the way it is suppose to be?
- No, your transmission linkage needs to be adjusted. Careful here, if it's not right you can destroy your transmission.
3. Wow! I had know idea the engine vibrates so much, I have to tighten all clamps down after running, is this typical?
- Lots of vibration can be caused by a misfiring cylinder, bad motor mounts, or if it only does it in gear, you may have a mis-aligned motor. You do not want to "tighten down all the clamps" Those are the motor mounts which are used to align the motor with the shaft. You may need to replace them and then do a shaft alignment. Typically, the tolerance here should be around 4 one thousands of an inch between the transmission and the shaft coupling (with the shaft uncoupled). The exact tolerance depends on your boat, but is often 1 one thousands of an inch for each inch of coupler diameter. This job can be a frustrating experience for a novice. You might consider having a certified mechanic inspect the mounts, replace if needed, and do a complete alignment. You might ask for a reference for a good mechanic from these boards because there are plenty of mechanics that don't follow the correct alignment procedures.
4. Maybe the engine is not aligned with shaft, will this cause wear, virbration if not perfect?
- Yes and worse. See above.
5. Frame fuel filter w/ glass jar rod running through center to hold in place w/plastic nut, slow drip. Does this have washer of type?
- This slow drip when you are not running probably turns into a source of air entering your fuel system when running (especially above idle). Air in your fuel system may be the cause of your misfire and vibration. You need to fix the leak, bleed the air from the low pressure side, then the high pressure side of your fuel system. Most engine trouble is a result of fuel system trouble.
6. Shaft log - How long does packing last? What kind of signs do you look for when it wears.
- The packing life span depends on the hours, shaft alignment, habits of the driver, etc. If it is a traditional system it should drip once a minute when running. If it drips more then it need to be adjusted or serviced. If it's a dripless system then it shouldn't drip.
