Hes getting injectors worked on and Fuel Tank removed and new fuel, and what ever else the hospital finds...doing exploratory surgery. Send donations to LOLA c/o Myrtle Beach Yacht Club, Little River, SC

They have more Q&A that are very detailed and worthwhile.
I am considering the purchase of a 30 foot sailboat with a 13 HP diesel. Several reports indicate this power plant is underpowered for this size boat. Any comments, solutions (if a significant problem)? Thanks, Andy
[JED] If your vessel is indeed underpowered, the addition of a more efficient propellor for your engine / hull configuration will assure all the engine's power is used in driving the vessel. Let's assume the engine is in good mechanical condition, and is capable of running at it's rated power output. (Don't jump this hurdle yet, many diesels don't make their rated power due to restricted fuel systems, old fuel, restricted air or exhaust systems, maladjusted control cables or governors, leaky valves, improper injection timing, etc.)
Here is a rule of thumb for displacement hulls.
If a fixed propellor, ensure the engine is reaching max rpm while the boat reaches hull speed. This will allow the engine to attain it's maximum power, and drive the boat efficiently. There should be no black smoke at hull speed, as this indicates the engine is overloaded. Assuming the boat's bottom is clean, and the engine is getting sufficient air, [clean air filter, etc.] black smoke at hull speed means the propellor is too steeply pitched. (There are a few more reasons for black smoke, but we are talking propellors.)
Folding props of the racing type [Martec brand] are great under sail, but are not designed for efficientcy under power. This is fine with commited racers.
Folding props such as Max Prop would be advantageous for most any sailboat, due to manual blade pitch adjustability, and excellent astern powering ability. They also make minimal resistance when sailing. They are expensive, however. This is the route I would take, were I in your situation.
lola--i posted a comment for ya----re the selling of a 2qm20h yanmar-----from another forum-----goood luck---could help ya !!!! and ya can never have too many spare engine parts.......this one spozedly runs ok.......is just like the one i have in my ericson....
UPDATE: HIS NEW PARTS ARE BEING WORKED ON AND WILL BE TIED UP FOR A FEW WEEKS
HE IS TO WATCH HIS DIET AND EXERCISE MORE....SEE THE FOLLOWING
We have sent injector and the fuel injection pump to the rebuild shop in New Jersey. The major problem is that the fuel metering adjustment screw on the pump had come loose some time ago and crept out of calibration. There is also a sticking fuel plunger and some old water damage. This shop has the pump test equipment to calibrate and run test the pump after repairs. We should get the pump back next week. You can assure your friends that we will time the pump properly when we install it. I' all let you know what develops
